The important structures of the wrist can be divided into several categories. These include

• bones and joints
• ligaments and tendons
• muscles
• nerves
• blood vessels

Bones and Joints

There are 15 bones that form connections from the end of the forearm to the hand. The wrist itself contains eight small bones, called carpal bones.  These bones are grouped in two rows across the wrist. The proximal row is where the wrist creases when you bend it. Beginning with the thumb-side of the wrist, the proximal row of carpal bones is made up of the scaphoid, lunate, and triquetrum. The second row of carpal bones, called the distal row. meets the proximal row a little further toward the fingers. The distal row is made up of the trapezium, trapezoid, capitate, hamate, and pisiform bones.

The proximal row of carpal bones connects the two bones of the forearm, the radius and the ulna, to the bones of the hand. The bones of the hand are called the
metacarpal bones. These are the long bones that lie within the palm of the hand. The metacarpals attach to the phalanges, which are the bones in the fingers and thumb.

One reason that the wrist is so complicated is because every small carpal bone forms a joint with the bone next to it. This means that what we call the wrist joint is actually made up of many small joints. Articular cartilage  is the material that covers the ends of the bones of any joint. Articular cartilage can be up to one-quarter of an inch thick in the large, weight-bearing joints. It is thinner in joints such as the wrist that don’t support a lot of weight. Articular cartilage is white, shiny, and has a rubbery consistency. It is slippery, which allows the joint surfaces to slide against one another without causing
any damage.

The function of articular cartilage is to absorb shock and provide an extremely smooth surface to make motion easier. We have articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate. In the wrist, articular cartilage covers the sides of all the carpals and the ends of the bones that connect from the forearm to the fingers.

Ligaments and Tendons

Ligaments are soft tissue structures that connect bones to bones. The ligaments around a joint usually combine to form a joint capsule. A joint capsule is a watertight sac that surrounds a joint and contains lubricating fluid called synovial fluid. In the wrist, the eight carpal bones are surrounded and supported by a joint capsule.

Two important ligaments support the sides of the wrist. These are the collateral ligaments. There are two collateral ligaments that connect the forearm to the wrist, one on each side of the wrist.

As its name suggests, the ulnar collateral ligament (UCL) is on the ulnar side of the wrist. It crosses the ulnar edge (the side away from the thumb) of the wrist. It starts at the ulnar styloid, the small bump on the edge of the wrist (on the side away from the thumb) where the ulna meets the wrist joint. There are two parts to the cord-shaped UCL. One part connects to the pisiform (one of the small carpal bones) and to the transverse carpal ligament, a thick band of tissue that crosses in front of the wrist. The other goes to the triquetrum (a small carpal bone near the ulnar side of the wrist). The UCL adds support to a small disc of cartilage where the ulna meets the wrist. This structure is called the triangular fibrocartilage complex (TFCC) and is discussed in more detail below. The UCL stabilizes the TFCC and keeps the wrist from bending too far to the side (toward the thumb).

The radial collateral ligament (RCL) is on the thumb side of the wrist. It starts on the outer edge of the radius on a small bump called the radial styloid. It connects to the side of the scaphoid, the carpal bone below the thumb. The RCL prevents the wrist from bending too far to the side (away from the thumb).

Just as there are many bones that form the wrist, there are many ligaments that connect to and support these bones. Injury or problems that cause these ligaments to stretch or tear can eventually lead to arthritis in the wrist.

At the wrist, the end of the ulna bone of the forearm articulates with two carpal bones, the lunate and the triquetrum. A unique structure mentioned earlier, the triangular fibrocartilage complex (TFCC), sits between the ulna and these two carpal bones. The TFCC is a small cartilage pad that cushions this part of the wrist joint. It also improves the range of motion and gliding action within the wrist joint.

There are several important tendons that cross the wrist. Tendons connect muscles to bone. The tendons that cross the wrist begin as muscles that start in the forearm. Those that cross the palm side of the wrist are the flexor tendons. They curl the fingers and thumb, and they bend the wrist. The flexor tendons run beneath the transverse carpal ligament (mentioned earlier). This structure lies on the palm side of the wrist. This band of tissue keeps the flexor tendons from bowing outward when you curl your fingers, thumb, or wrist. The tendons that travel over the back of the wrist, the extensor tendons, run through a series of tunnels, called compartments. These compartments are lined with a slick substance called tenosynovium, which prevents friction as the extensor tendons glide inside their compartment.

Muscles

The main muscles that are important at the wrist have been mentioned above in the discussion about tendons. These muscles generally start further up in the forearm. The tendons of these muscles cross the wrist. They control the actions of the fingers, thumb, and wrist.

Nerves

All of the nerves that travel to the hand cross the wrist. Three main nerves begin together at the shoulder: the radial nerve, the median nerve, and the ulnar nerve. These nerves carry signals from the brain to the muscles that move the arm, hand, fingers, and thumb. The nerves also carry signals back to the brain about sensations such as touch, pain, and temperature.

The radial nerve runs along the thumb-side edge of the forearm. It wraps around the end of the radius bone toward the back of the hand. It gives sensation to the back of the
hand from the thumb to the third finger. It also goes to the back of the thumb and just beyond the main knuckle of the back surface of the ring and middle fingers.

The median nerve travels through a tunnel within the wrist called the carpal tunnel. The median nerve gives sensation to the palm sides of the thumb, index finger, long finger, and half of the ring finger. It also sends a nerve branch to control the thenar muscles of the thumb. The thenar muscles help move the thumb and let you touch the pad of the thumb to the tips each of each finger on the same hand, a motion called opposition.

The ulnar nerve travels through a separate tunnel, called Guyon’s canal. This tunnel is formed by two carpal bones (the pisiform and hamate), and the ligament that connects them. After passing through the canal, the ulnar nerve branches out to supply feeling to the little finger and half the ring finger. Branches of this nerve also supply the small muscles in the palm and the muscle that pulls the thumb toward the palm.

The nerves that travel through the wrist are subject to problems. Constant bending and straightening of the wrist and fingers can lead to irritation or pressure on the nerves
within their tunnels and cause problems such as pain, numbness, and weakness in the hand, fingers, and thumb.

Blood Vessels

Traveling along with the nerves are the large vessels that supply the hand with blood. The largest artery is the radial artery that travels across the front of the wrist, closest to the thumb. The radial artery is where the pulse is taken in the wrist. The ulnar artery runs next to the ulnar nerve through Guyon’s canal (mentioned earlier). The ulnar and radial arteries arch together within the palm of the hand, supplying the front of the hand and fingers. Other arteries travel across the back of the wrist to supply the back of the hand and fingers.

As you can see, the wrist is a complex area of the body. When you realize all the different ways we use our hands every day and all the different positions we put our hands in, it is easy to understand how hard daily life can be when the wrist doesn’t work well.

 

cramioclavicular( AC) joint

The important structures of the shoulder can be divided into several categories. These include

• bones and joints
• ligaments and tendons
• muscles
• nerves
• blood vessels
• bursae

Bones and Joints

The bones of the shoulder are the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The roof of the shoulder is formed by a part of the scapula called the acromion.

There are actually four joints that make up the shoulder. The main shoulder joint, called the glenhumeral joint

is formed where the ball of the humerus fits into a shallow socket on the scapula. This shallow socket is called the glenoid.

The acromioclavicular (AC) joint is where the clavicle meets the acromion. The sternoclavicular (SC) joint supports the connection of the arms and shoulders to the main skeleton on the front of the chest.

A false joint is formed where the shoulder blade glides against the thorax (the rib cage). This joint, called the scapulothoracic joint.  is important because it requires that the muscles surrounding the shoulder blade work together to keep the socket lined up during shoulder movements.

Articular cartilage is the material that covers the ends of the bones of any joint. Articular cartilage is about one-quarter of an inch thick in most large, weight-bearing joints. It is a bit thinner in joints such as the shoulder, which don’t normally support weight. Articular cartilage is white and shiny and has a rubbery consistency. It is slippery, which allows the joint surfaces to slide against one another without causing any damage. The function of articular cartilage is to absorb shock and provide an extremely smooth surface to make motion easier. We have articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate. In the shoulder, articular cartilage covers the end of the humerus and socket area of the glenoid on the scapula.

Ligaments and Tendons

There are several important ligaments in the shoulder. Ligaments are soft tissue structures that connect bones to bones. A joint capsule is a watertight sac that surrounds a joint. In the shoulder, the joint capsule is formed by a group of ligaments that connect the humerus to the glenoid. These ligaments are the main source of stability for the shoulder. They help hold the shoulder in place and keep it from dislocating.

Ligaments attach the clavicle to the acromion in the AC joint. Two ligaments connect the clavicle to the scapula by attaching to the coracoid process, a bony knob that sticks out of the scapula in the front of the shoulder.

A special type of ligament forms a unique structure inside the shoulder called the labrum. The labrum is attached almost completely around the edge of the glenoid. When viewed in cross section, the labrum is wedge-shaped. The shape and the way the labrum is attached create a deeper cup for the glenoid socket. This is important because the glenoid socket is so flat and shallow that the ball of the humerus does not fit tightly. The labrum creates a deeper cup for the ball of the humerus to fit into.

The labrum is also where the biceps tendon attaches to the glenoid. Tendons are much like ligaments, except that tendons attach muscles to bones. Muscles move the bones by pulling on the tendons. The biceps tendon runs from the biceps muscle, across the front of the shoulder, to the glenoid. At the very top of the glenoid, the biceps tendon attaches to the bone and actually becomes part of the labrum. This connection can be a source of problems when the biceps tendon is damaged and pulls away from its attachment to the glenoid.

The tendons of the rotator cuff are the next layer in the shoulder joint. Four rotator cuff tendons connect the deepest layer of muscles to the humerus.

Muscles

The rotator cuff tendons attach to the deep rotator cuff muscles. This group of muscles lies just outside the shoulder joint. These muscles help raise the arm from the side and rotate the shoulder in the many directions. They are involved in many day-to-day activities. The rotator cuff muscles and tendons also help keep the shoulder joint stable by holding the humeral head in the glenoid socket.

The large deltoid muscle is the outer layer of shoulder muscle. The deltoid is the largest, strongest muscle of the shoulder. The deltoid muscle takes over lifting the arm once the arm is away from the side.

Nerves

All of the nerves that travel down the arm pass through the axilla (the armpit) just under the shoulder joint. Three main nerves begin together at the shoulder: the radial nerve, the ulnar nerve, and the median nerve. These nerves carry the signals from the brain to the muscles that move the arm. The nerves also carry signals back to the brain about sensations such as touch, pain, and temperature.

Blood Vessels

Traveling along with the nerves are the large vessels that supply the arm with blood. The large axillar artery travels through the axilla. If you place your hand in your armpit, you may be able to feel the pulsing of this large artery. The axillary artery has many smaller branches that supply blood to different parts of the shoulder. The shoulder has a very rich blood supply.

Bursae

Sandwiched between the rotator cuff muscles and the outer layer of large bulky shoulder muscles are structures known as bursae. Bursae are everywhere in the body. They are found wherever two body parts move against one another and there is no joint to reduce the friction. A single bursa is simply a sac between two moving surfaces that contains a small amount of lubricating fluid.

Think of a bursa like this: If you press your hands together and slide them against one another, you produce some friction. In fact, when your hands are cold you may rub them together briskly to create heat from the friction. Now imagine that you hold in your hands a small plastic sack that contains a few drops of salad oil. This sack would let your hands glide freely against each other without a lot of friction.

As you can see, the shoulder is extremely complex, with a design that provides maximum mobility and range of motion. Besides big lifting jobs, the shoulder joint is also responsible for getting the hand in the right position for any function. When you realize all the different ways and positions we use our hands every day, it is easy to understand how hard daily life can be when the shoulder isn’t working well.

There are 27 bones within the wrist and hand. The wrist itself contains eight small bones, called carpals.  The carpals join with the two forearm bones, the radius and ulna, forming the wrist joint. Further into the palm, the carpals connect to the
metacarpals. There are five metacarpals forming the palm of the hand. One metacarpal connects to each finger and thumb. Small bone shafts called phalanges line up to form each finger and thumb.

The main knuckle joints are formed by the connections of the phalanges to the metacarpals. These joints are called the metacarpophalangeal joints  (MCP joints). The MCP joints work like a hinge when you bend and straighten your fingers and thumb.

The three phalanges in each finger are separated by two joints, called interphalangeal joints (IP joints). The one closest to the MCP joint (knuckle) is called the
proximal IP joint (PIP joint). The joint near the end of the finger is called the distal IP joint (DIP joint). The thumb only has one IP joint between the two thumb phalanges. The IP joints of the digits also work like hinges when you bend and straighten your fingers and thumb.

The joints of the hand, fingers, and thumb are covered on the ends with articular cartilage.  This white, shiny material has a rubbery consistency. The function of articular cartilage is to absorb shock and provide an extremely smooth surface to
facilitate motion. There is articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate.

Ligaments are tough bands of tissue that connect bones together. Two important structures, called collateral ligaments , are found on either side of each finger and thumb joint. The function of the collateral ligaments is to prevent abnormal sideways bending of each joint.

In the PIP joint (the middle joint between the main knuckle and the DIP joint), the strongest ligament is the volar plate.  This ligament connects the proximal phalanx
to the middle phalanx on the palm side of the joint. The ligament tightens as the joint is straightened and keeps the PIP joint from bending back too far (hyperextending). Finger deformities can occur when the volar plate loosens from disease or injury.

The tendons that allow each finger joint to straighten are called the extensor tendons. The extensor tendons of the fingers begin as muscles that arise from the backside of the forearm bones. These muscles travel towards the hand, where they
eventually connect to the extensor tendons before crossing over the back of the wrist joint. As they travel into the fingers, the extensor tendons become the extensor hood.  The extensor hood flattens out to cover the top of the finger and sends out branches on each side that connect to the bones in the middle and end of the finger.

The place where the extensor tendon attaches to the middle phalanx is called the central slip.  When the extensor muscles contract, they tug on the extensor tendon and straighten the finger. Problems occur when the central slip is damaged, as can happen with a tear.

Many of the muscles that control the hand start at the elbow or forearm. They run down the forearm and cross the wrist and hand. Some control only the bending or straightening of the wrist. Others influence motion of the fingers or thumb. Many of these muscles help position and hold the wrist and hand while the thumb and fingers grip or perform fine motor actions.

Most of the small muscles that work the thumb and pinky finger start on the carpal bones. These muscles connect in ways that allow the hand to grip and hold. Two muscles allow the thumb to move across the palm of the hand, an important function called thumb opposition.

The smallest muscles that originate in the wrist and hand are called the intrinsic muscles. The intrinsic muscles guide the fine motions of the fingers by getting the fingers positioned and holding them steady during hand activities.

All of the nerves that travel to the hand and fingers begin together at the shoulder: the radial nerve, the median nerve, and the ulnar nerve. These nerves
carry signals from the brain to the muscles that move the arm, hand, fingers, and thumb. The nerves also carry signals back to the brain about sensations such as touch, pain, and temperature.

The radial nerve  runs along the thumb-side edge of the forearm. It wraps around the end of the radius bone toward the back of the hand. It gives sensation to the back of the hand from the thumb to the third finger. It also supplies the back of the thumb and just beyond the main knuckle of the back surface of the ring and middle fingers.

The median nerve travels through a tunnel within the wrist called the carpal tunnel. This nerve gives sensation to the thumb, index finger, long finger, and half of the ring finger. It also sends a nerve branch to control the thenar muscles of the thumb. The thenar muscles help move the thumb and let you touch the pad of the thumb to the tips each of each finger on the same hand, a motion called opposition.

The ulnar nerve  travels through a separate tunnel, called Guyon’s canal. This tunnel is formed by two carpal bones, the pisiform and hamate, and the ligament that connects them. After passing through the canal, the ulnar nerve branches out to supply feeling to the little finger and half the ring finger. Branches of this nerve also supply the small muscles in the palm and the muscle that pulls the thumb toward the palm.

The nerves that travel to the hand are subject to problems. Constant bending and straightening of the wrist and fingers can lead to irritation or pressure on the nerves within their tunnels and cause problems such as pain, numbness, and weakness in the hand, fingers, and thumb.

Traveling along with the nerves are the large vessels that supply the hand with blood. The largest artery is the radial artery that travels across the front of the wrist, closest to the thumb. The radial artery is where the pulse is taken in the wrist. The ulnar artery runs next to the ulnar nerve through Guyon’s canal (mentioned earlier). The ulnar and radial arteries arch together within the palm of the hand, supplying the front of the hand, fingers, and thumb. Other arteries travel across the back of the wrist to supply the back of the hand, fingers, and thumb.

The hand is formed of numerous structures that have an important role in normal hand function. Conditions that change the way these structures work can greatly impact whether the hand functions normally. When our hands are free of problems, it’s easy to take the complex anatomy of the hand for granted.

As you can see, the hip is complex with a design that provides a good amount of stability. It allows good mobility and range of motion for doing a wide range of daily activities. Many powerful muscles connect to and cross by the hip joint, making it possible for us to accelerate quickly during actions like running and jumping.

To better understand how knee problems occur, it is important to understand some of the anatomy of the knee joint and how the parts of the knee work together to maintain normal function.

First, we will define some common anatomic terms as they relate to the knee. This will make it clearer as we talk about the structures later.

Many parts of the body have duplicates. So it is common to describe parts of the body using terms that define where the part is in relation to an imaginary line drawn through the middle of the body. For example, medial means closer to the midline. So the medial side of the knee is the side that is closest to the other knee. The lateral side of the knee is the side that is away from the other knee. Structures on the medial side usually have medial as part of their name, such as the medial meniscus. The term anterior refers to the front of the knee, while the term posterior refers to the back of the knee. So the anterior cruciate ligament is in front of the posterior cruciate ligament.

Bones and Joints

The knee is the meeting place of two important bones in the leg, the femur (the thighbone) and the tibia (the shinbone). The patella (or kneecap, as it is commonly called) is made of bone and sits in front of the knee.

The knee joint is a synovial joint. Synovial joins are enclosed by a ligament capsule and contain a fluid, called synovial fluid, that lubricates the joint.

The end of the femur joins the top of the tibia to create the knee joint. Two round knobs called femoral condyles are found on the end of the femur. These condyles rest on the top surface of the tibia. This surface is called the tibial plateau. The outside half (farthest away from the other knee) is called the lateral tibial plateau, and the inside half (closest to the other knee) is called the medial tibial plateau. The patella glides through a special groove formed by the two femoral condyles called the patellofemoral groove.

The smaller bone of the lower leg, the fibula, never really enters the knee joint. It does have a small joint that connects it to the side of the tibia. This joint normally moves very little.

Articular cartilage is the material that covers the ends of the bones of any joint. This material is about one-quarter of an inch thick in most large joints. It is white and shiny with a rubbery consistency. Articular cartilage is a slippery substance that allows the surfaces to slide against one another without damage to either surface. The function of articular cartilage is to absorb shock and provide an extremely smooth surface to facilitate motion. We have articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate. In the knee, articular cartilage covers the ends of the femur, the top of the tibia, and the back of the patella.

Ligaments and Tendons

Ligaments are tough bands of tissue that connect the ends of bones together. Two important ligaments are found on either side of the knee joint. They are the medial collateral ligament (MCL) and the lateral collateral ligament (LCL).

Inside the knee joint, two other important ligaments stretch between the femur and the tibia: the anterior cruciate ligament (ACL) in front, and the posterior cruciate ligament (PCL) in back.

The MCL and LCL prevent the knee from moving too far in the side-to-side direction. The ACL and PCL control the front-to-back motion of the knee joint.

The ACL keeps the tibia from sliding too far forward in relation to the femur. The PCL keeps the tibia from sliding too far backward in relation to the femur. Working together, the two cruciate ligaments control the back-and-forth motion of the knee. The ligaments, all taken together, are the most important structures controlling stability of the knee.

Two special types of ligaments called menisci sit between the femur and the tibia. These structures are sometimes referred to as the cartilage of the knee, but the menisci differ from the articular cartilage that covers the surface of the joint.

The two menisci of the knee are important for two reasons: (1) they work like a gasket to spread the force from the weight of the body over a larger area, and (2) they help the ligaments with stability of the knee.

Imagine the knee as a ball resting on a flat plate, The ball is the end of the thighbone as it enters the joint, and the plate is the top of the shinbone. The menisci actually wrap around the round end of the upper bone to fill the space between it and the flat shinbone. The menisci act like a gasket, helping to distribute the weight, from the femur to the tibia.

Without the menisci, any weight on the femur will be concentrated to one point on the tibia. But with the menisci, weight is spread out across the tibial surface. Weight distribution by the menisci is important because it protects the articular cartilage on the ends of the bones from excessive forces. Without the menisci, the concentration of force into a small area on the articular cartilage can damage the surface, leading to degeneration over time.

In addition to protecting the articular cartilage, the menisci help the ligaments with stability of the knee. The menisci make the knee joint more stable by acting like a wedge set against the bottom of a car tire. The menisci are thicker around the outside, and this thickness helps keep the round femur from rolling on the flat tibia. The menisci convert the tibial surface into a shallow socket. A socket is more stable and more efficient at transmitting the weight from the upper body than a round ball on a flat plate. The menisci enhance the stability of the knee and protect the articular cartilage from excessive concentration of force.

 

Taken all together, the ligaments of the knee are the most important structures that stabilize the joint. Remember, ligaments connect bones to bones. Without strong, tight ligaments to connect the femur to the tibia, the knee joint would be too loose. Unlike other joints in the body, the knee joint lacks a stable bony configuration. The hip joint, for example, is a ball that sits inside a deep socket. The ankle joint has a shape similar to a mortise and tenon, a way of joining wood used by craftsmen for centuries.

Tendons are similar to ligaments, except that tendons attach muscles to bones. The largest tendon around the knee is the patellar tendon. This tendon connects the patella (kneecap) to the tibia. This tendon covers the patella and continues up the thigh.

There it is called the quadriceps tendon since it attaches to the quadriceps muscles in the front of the thigh. The hamstring muscles on the back of the leg also have tendons that attach in different places around the knee joint. These tendons are sometimes used as tendon grafts to replace torn ligaments in the knee.

Muscles

The extensor mechanism is the motor that drives the knee joint and allows us to walk. It sits in front of the knee joint and is made up of the patella, the patellar tendon, the quadriceps tendon, and the quadriceps muscles. The four quadriceps muscles in front of the thigh are the muscles that attach to the quadriceps tendon. When these muscles contract, they straighten the knee joint, such as when you get up from a squatting position.

The way in which the kneecap fits into the patellofemoral groove on the front of the femur and slides as the knee bends can affect the overall function of the knee. The patella works like a fulcrum, increasing the force exerted by the quadriceps muscles as the knee straightens. When the quadriceps muscles contract, the knee straightens.

The hamstring muscle are the muscles in the back of the knee and thigh. When these muscles contract, the knee bends.

Nerves

The most important nerve around the knee is the popliteal nerve in the back of the knee. This large nerve travels to the lower leg and foot, supplying sensation and muscle control. The nerve splits just above the knee to form the tibial nerve and the peroneal nerve. The tibial nerve continues down the back of the leg while the peroneal nerve travels around the outside of the knee and down the front of the leg to the foot. Both of these nerves can be damaged by injuries around the knee.

Blood Vessels

The major blood vessels around the knee travel with the popliteal nerve down the back of the leg. The popliteal artery and popliteal vein are the largest blood supply to the leg and foot. If the popliteal artery is damaged beyond repair, it is very likely the leg will not be able to survive. The popliteal artery carries blood to the leg and foot. The popliteal vein carries blood back to the heart.

The knee has a somewhat unstable design. Yet it must support the body’s full weight when standing, and much more than that during walking or running. So it’s not surprising that knee problems are a fairly common complaint among people of all ages. Understanding the basic parts of the knee can help you better understand what happens when knee problems occur.

Where does fibromyalgia develop?

Pain in fibromyalgia is present in soft tissues throughout the body. Pain and stiffness concentrate in spots such as the neck and lower back. The tender spots don’t seem to be inflamed. Most tests show nothing out of the ordinary in the anatomy of people with fibromyalgia.

Why does fibromyalgia develop?

The causes of fibromyalgia are unknown, but one thing is for sure: you’re not making it up. Many sufferers have been told that it’s all in your head by family members or other doctors. It is true that people with fibromyalgia are often depressed, and that stress worsens symptoms. But depression and stress don’t seem to be the driving forces behind the disease.

Fibromyalgia often occurs along with other conditions, such as other forms of arthritis, Lyme disease, or thyroid problems. It can also develop after a serious injury. These problems may cause the fibromyalgia to develop.

About 80 percent of all fibromyalgia patients report serious problems sleeping. Because fibromyalgia is so strongly connected to sleep disturbance, in some cases it is possible that the sleep disturbance is the major cause. In fact, studies have produced fibromyalgia-like symptoms in healthy adults by disrupting their sleep patterns.

There is some evidence that fibromyalgia is linked with autoimmune disorders, in which your immune system attacks the tissues of your own body. Sufferers have lower pain thresholds and lower levels of serotonin, a brain chemical involved in pain, sleep, and mood. However, it’s unclear whether these conditions cause the fibromyalgia or are a result of the disease.

What does fibromyalgia feel like?

The symptoms of fibromyalgia are long lasting and intense. However, they can vary from day to day. Symptoms include

• pain and stiffness throughout the body, with especially tender points near certain joints
• a feeling of exhaustion that sleep often does not help
• sleep problems
• tension headaches
• numbness or tingling in the arms, hands and/or feed
• a feeling of swelling in the hands, although this is not confirmed in physical exams
• constipation and diarrhea along with abdominal pain (known as irritable bowel syndrome)
• intense PMS pains in women
• depression
• interuppted sleep or awakening still feeling tired
• tiredness
• morning stiffness
• swelling sensation
• bothered by light, odours, and/or noise
• poor concentration and memory loss
• irritable bowel syndrome
• changes in vision
• sore glands

How do health care providersidentify fibromyalgia?

Blood tests and X-rays don’t show fibromyalgia in your body. However, your health care provider may do these tests to rule out other conditions. There are really only two tools used to diagnose fibromyalgia. One is your history of symptoms. The other involves putting pressure on eighteen tender point sites. If you feel pain in eleven of these eighteen sites, you are considered to have fibromyalgia. (However, it is still possible that you can have the disease with pain in fewer sites.)

In some patients, doctors may recommend X-rays to look at the bones near painful spots. The X-rays will not show fibromyalgia but are used to make sure there are no other causes of your pain. Other special tests such as electromyograms, which measure the contraction of muscles, may be used to try to determine if the muscles show abnormalities. Most of the time these tests are negative. A sleep history, and possibly a sleep study, could be important to the diagnosis.

Chronic fatigue syndrome (CFS) may need to be ruled out. CFS is another disease that is difficult to diagnose and has puzzled doctors for many years. CFS and fibromyalgia share many symptoms, especially the severe exhaustion. The major difference is that CFS causes flu-like symptoms, such as low-grade fevers, sore throats, and swollen lymph nodes.

What can be done for the condition?

When you visit FIT4YOU Physiotherapy, the first step in the treatment of your fibromyalgia is to help you understand this complex and frustrating disease. Many patients are relieved to learn that the disease is not all in their head, and that our therapists can develop a program to help manage pain and exhaustion. 

It is uncertain whether fibromyalgia is ever cured. Like many chronic diseases, the symptoms of the disease can be controlled. The successful treatment of fibromyalgia is very much a joint effort between doctor, physical therapist and patient.

You must be willing to make lifestyle changes as well as give attention to your psychological health to help control the symptoms. Other treatments or lifestyle changes we may recommend include:

• exercise
• biofeedback
• meditation
• acupuncture
• pain medication
• anti-inflammatory drugs
• cortisone injected into painful points
• ultrasound treatments
• massage
• heat for temporary pain relief
• counseling to help deal with the symptoms

Any treatment program will likely last for many years but patients do get better. At FIT4YOU Physiotherapy, our goal is to help you keep your pain under control so that you can enjoy your normal activities and lifestyle. Recent studies show that about 25 percent of patients treated for fibromyalgia were in remission at the end of two years. Many others have reduced their pain to tolerable levels.

At first, the elbow seems like a simple hinge. But when the complexity of the interaction of the elbow with the forearm and wrist is understood, it is easy to see why the elbow can cause problems when it does not function correctly. Part of what makes us human is the way we are able to use our hands. Effective use of our hands requires stable, painless elbow joints.

This guide will help you understand

• what parts make up the elbow
• how those parts work together

The important structures of the elbow can be divided into several categories. These include

• bones and joints
• ligaments and tendons
• muscles
• nerves

The bones of the elbow are the humerus (the upper arm bone), the ulna (the larger bone of the forearm, on the opposite side of the thumb), and the radius (the smaller bone of the forearm on the same side as the thumb). The elbow itself is essentially a hinge joint, meaning it bends and straightens like a hinge. But there is a second joint where the end of the radius (the radial head) meets the humerus. This joint is complicated because the radius has to rotate so that you can turn your hand palm up and palm down. At the same time, it has to slide against the end of the humerus as the elbow bends and straightens. The joint is even more complex because the radius has to slide against the ulna as it rotates the wrist as well. As a result, the end of the radius at the elbow is shaped like a smooth knob with a cup at the end to fit on the end of the humerus. The edges are also smooth where it glides against the ulna.

Articular Caritilage:  is the material that covers the ends of the bones of any joint. Articular cartilage can be up to one-quarter of an inch thick in the large, weight-bearing joints. It is a bit thinner in joints such as the elbow, which don’t support weight. Articular cartilage is white, shiny, and has a rubbery consistency. It is slippery, which allows the joint surfaces to slide against one another without causing any damage.

The function of articular cartilage is to absorb shock and provide an extremely smooth surface to make motion easier. We have articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate. In the elbow, articular cartilage covers the end of the humerus, the end of the radius, and the end of the ulna.

Ligaments and Tendons

There are several important ligaments in the elbow. Ligaments are soft tissue structures that connect bones to bones. The ligaments around a joint usually combine together to form a joint capsule. A joint capsule is a watertight sac that surrounds a joint and contains lubricating fluid called synovial fluid.

In the elbow, two of the most important ligaments are the medial collateral ligament and the lateral collateral ligament.  The medial collateral is on the inside edge of the elbow, and the lateral collateral is on the outside edge. Together these two ligaments connect the humerus to the ulna and keep it tightly in place as it slides through the groove at the end of the humerus. These ligaments are the main source of stability for the elbow. They can be torn when there is an injury or dislocation to the elbow. If they do not heal correctly the elbow can be too loose, or unstable.

There is also an important ligament called the annular ligament that wraps around the radial head and holds it tight against the ulna. The word annular means ring shaped, and the annular ligament forms a ring around the radial head as it holds it in place. This ligament can be torn when the entire elbow or just the radial head is dislocated.

There are several important tendons around the elbow. The biceps tendon attaches the large biceps muscle on the front of the arm to the radius. It allows the elbow to bend with force. You can feel this tendon crossing the front crease of the elbow when you tighten the biceps muscle.

The triceps tendon connects the large triceps muscle on the back of the arm with the ulna. It allows the elbow to straighten with force, such as when you perform a push-up.

The muscles of the forearm cross the elbow and attach to the humerus. The outside, or lateral, bump just above the elbow is called the lateral epicoondyle. Most of the muscles that straighten the fingers and wrist all come together in one tendon to attach in this area. The inside, or medial, bump just above the elbow is called the medial epicondyle. Most of the muscles that bend the fingers and wrist all come together in one tendon to attach in this area. These two tendons are important to understand because they are a common location of tendonitis.

Muscles

The main muscles that are important at the elbow have been mentioned above in the discussion about tendons. They are the biceps, the triceps, the wrist extensors (attaching to the lateral epicondyle) and the wrist flexors (attaching to the medial epicondyle).

Nerves

All of the nerves that travel down the arm pas across the elbow. Three main nerves begin together at the shoulder: the radial nerve, the ulnar nerve, and the median nerve. These nerves carry signals from the brain to the muscles that move the arm. The nerves also carry signals back to the brain about sensations such as touch, pain, and temperature.

Some of the more common problems around the elbow are problems of the nerves. Each nerve travels through its own tunnel as it crosses the elbow. Because the elbow must bend a great deal, the nerves must bend as well. Constant bending and straightening can lead to irritation or pressure on the nerves within their tunnels and cause problems such as pain, numbness, and weakness in the arm and hand.

Blood Vessels

Traveling along with the nerves are the large vessels that supply the arm with blood. The largest artery is the brachial artery that travels across the front crease of the elbow. If you place your hand in the bend of your elbow, you may be able to feel the pulsing of this large artery. The brachial artery splits into two branches just below the elbow: the ulnar artery and the radial artery that continue into the hand. Damage to the brachial artery can be very serious because it is the only blood supply to the hand.

As you can see, the elbow is more than a simple hinge. It is designed to provide maximum stability as we position our forearm to use our hand. When you realize all the different ways we use our hands every day and all the different positions we put our hands in, it is easy to understand how hard daily life can be when the elbow doesn’t work well.

What causes CTD?

Opinions abound as to what may cause CTD, but there is very little agreement. Some of the theories about how CTD starts are described below. The theories include

• overuse
• muscle tension
• nerve tension
• psychosocial factors
• mind-body interaction
• contributing factors

Using muscles and joints after they have become fatigued, or overly tired, increases the likelihood of injury. Overloaded muscles and soft tissues without proper rest have no chance to recover fully. This problem often hampers athletes who have to throw, jump, or run repeatedly. It can also affect people who work in jobs where they keep doing the same action again and again, such as typing, gripping, and lifting.

All body tissues are in a constant state of change. Minor damage occurs continuously, which the body must repair in the normal course of a day. But the damage can occur faster than the repair mechanisms can keep up with it. When this happens, the tissues become weaker. They may begin to hurt. The weaker the tissues become, the more likely they will suffer even more damage. A cycle begins that looks like a spiral–constantly downward.

Muscle Tension

Some doctors think muscle tension causes CTD. To function, or work properly, the body and each of its parts needs a steady supply of blood, rich in oxygen and nutrients. Nutrients are the body’s fuel–glucose, for example. Cutting off or slowing the blood supply harms the tissues of the body.

Tense muscles are believed by some to actually squeeze off their own flow of energy and fuel. Muscles can get energy without oxygen, but the process produces a chemical called lactic acid. This chemical can be a potent pain-causing chemical. Lactic acid is a chemical that can produce a burning feeling when muscles are overexercised. Some physicians believe that lactic acid produced by tense muscles may cause some of the symptoms of CTD.

As pain develops, muscles tighten even further because they attempt to guard the surrounding area. Guarding is a term that is used to describe a reflex that all muscles in the body share. When pain occurs anywhere in the body, muscles around the painful area go into spasm (they tighten uncontrollably) to try to limit the movement in the area. As a result, blood flow is slowed down even more. The muscles begin to ache more. The nerves that have their blood supply reduced and squeezed by muscles begin to tingle or go numb.

Nerve Tension

This theory suggests that nerves become extra sensitive when they’ve become shortened and irritable. It is thought that poor postures used over long periods causes muscles to bulk up and interfere with blood flow. The nerves that course through the body then become shortened and may begin to stick to the nearby tissues. Moving the arm or leg puts tension on the nerve and can cause pain to radiate along the limb. The problem is thought to get worse from stress because the muscles and nerves tense up and become even tighter. Also, when the same activities are done over and over again, the tight nerve is pulled and strained to the point that it can’t heal and eventually becomes a chronic source of symptoms.

Psychosocial Factors

Problems with CTD tend to be more common among people who suffer from boredom, who have poor working relations, who aren’t satisfied with their jobs, and who have unhappy social circumstances. Reasons why this is so are unclear. The number of CTD cases reported may also be influenced by state worker’s compensation rules. States where claims are processed quickly and with greater benefits tend to have higher volumes of CTD cases. Both of these findings suggest that many cases of CTD may be highly influenced by the patient’s perception of the overall situation. Some patients may subconsciously, or consciously, rationalize their symptoms due to many factors that are not medical but have to do with their overall job and social situation.

A newer theory suggests that there isn’t really an injury going on in the soft tissues where symptoms are felt. Instead, the problem is said to be coming from influences within the mind. It is theorized that the brain starts producing pain signals as a cover-up for deep-rooted feelings of past emotional pain or problems. Though the idea sounds hard to believe, practitioners using this approach claim they have had success rates as high as 95 percent. Their patients are reported to have gotten swift relief from treatments aimed at the underlying and unconscious emotional triggers.

The way people do their tasks can put them at risk for CTD. Some risk factors include

• force
• awkward or static postures
• poor tool and equipment design
• fatigue
• repetition
• temperature
• vibration

One of these risk factors alone may not cause a problem. But doing a task where several factors are present may pose a greater risk. And the longer a person is exposed to one or more risks, the greater the possibility of developing CTD. Many different symptoms can arise from the accumulation of small injuries or stresses to the body. CTD is not so much a disease as it is a response to excessive demands these factors can place on our bodies without giving them adequate time to recover between.

What does CTD feel like?

The symptoms of CTD usually start gradually. Patients usually don’t recall a single event that started their symptoms. They may report feelings of muscle tightness and fatigue at first. People commonly report feeling numbness, tingling, and vague pain. Others say they feel a sensation of swelling in the sore limb. Some patients with arm symptoms sense a loss of strength and may drop items because of problems with coordination. Symptoms often worsen with activity and ease with rest.

When you visit CITY SQUARE Physiotherapy, our therapist will begin the evaluation by taking a history of your problem. We’ll probably ask questions about your job, such as the type of work you do and how you perform your job tasks. Answers to other questions will give us information about your work conditions, such as the postures you use, the weights you have to lift or push, and whether you have to do repetitive tasks. We may also ask about how you like your job and whether you get along with your supervisors and coworkers.

Our therapist will then do a thorough physical examination. Your description of the symptoms and the physical examination are the most important parts in the diagnosis of CTD. We will first try to determine what conditions are affecting you. For example you may have symptoms of carpal tunnel syndrome or tennis elbow that need to be treated. Second, our therapist will try and determine if cumulative trauma is playing a role in your condition. If so, part of the treatment will be to try and eliminate the source of the cumulative trauma.

There are no specific tests that can diagnose CTD. There are many different tests that may be ordered as we look for specific conditions.

How can I help prevent problems of CTD?

The best medicine for treating CTD is to prevent the problem from occurring in the first place. Key items to consider when attempting to prevent problems with CTD are listed below.

Use healthy work postures and body alignment. Posture can have a significant role in CTD. Faulty alignment of the spine or limbs can be a source of symptoms. Using healthy posture and body alignment in all activities decreases the possibility that CTD will strike. Incorrect posture may lead to muscle imbalances or nerve and soft tissue pressure, leading to pain or other symptoms. Most people spend many hours at their work place, and using unhealthy posture during these long hours increases the likelihood that CTD will develop.

Ergonomics

Assessing where and how a person does work is called ergonomics. Even subtle changes in the way a work station is designed or how a job is done can lead to pain or injury.

Rest and Relax

Rest and relaxation (R and R) have recently become front-line defenses in the prevention of CTD. Methods can be as simple as deep breathing, walking, napping, or exercising.

This strategy is useful during work and off hours. Whether at home or work, our bodies need time to recover, which simply means giving them a chance to heal. Rest and relaxation allow the body to recover and provide a way of repairing these injured tissues along the way, keeping them healthy.

The following ideas may be used to foster rest and relaxation at work:

• Be relaxed. Try to work with your muscles relaxed by pacing your work schedule, staying well ahead of deadlines, and taking frequent breaks.
• Stop to exercise. Gentle exercise performed routinely through the day helps keep soft tissues flexible and can ease tension.
• Change positions. Plan ways to change positions during work tasks. This could include using a chair rather than standing or simply readjusting your approach to your job activity.
• Rotate jobs or share work duties. This can be fun by offering a new work setting, and it allows the body to recover from the demands of the previous job task.
• Avoid caffeine and tobacco. These can heighten stress, reduce blood flow, and elevate your perception of pain.

What can I expect with treatment?

Getting treated right away for symptoms of CTD can shorten the time it takes to heal. Symptoms can sometimes go away within two to four weeks when steps are taken quickly to address the factors that may be causing your symptoms. However, people who keep doing activities when they have symptoms and don’t seek help right away may be headed for a long and frustrating recovery time, perhaps as long as a year.

At FIT4YOU Physiotherapy many nonsurgical treatment approaches are used by our physical and occupational therapists to reduce the symptoms of CTD-related conditions. Our therapist will want to gather more information and will further evaluate your condition. The answers you give along with the results of the examination will guide us in tailoring a treatment program that is right for you.

Our therapists often begin by teaching patients relaxation techniques which may include helping you learn to breathe deeply by using your diaphragm muscle. Taking the time to relax and breathe deeply eases tense muscles and speeds nutrients and oxygen to sore tissues.

We may suggest that you wear a splint initially to protect and rest the sore area. Anti-inflammatory drugs, suggested by your doctor, are often used together with therapy treatments, which may include heat, ice, ultrasound, or gentle hands-on stretching to reduce pain or other symptoms. Our therapist may use muscle stretching to restore muscle balance and to improve your posture and alignment. We sometimes apply stretches that are designed to help nerves glide where they course from the spine to the arms or legs. Strengthening exercises are also used to restore muscle balance and to improve your ability to use healthy postures throughout the day.

Our therapist will pay close attention to your posture and movement patterns. You may receive verbal instruction and hands-on guidance to improve your alignment and movement habits. Helping you see and feel normal alignment improves your awareness about healthy postures and movements, allowing you to release tension and perform your activities with greater ease.

We will spend time helping you understand more about CTD and why you are experiencing symptoms. Our therapist may provide tips on how to combat symptoms at work using rest and relaxation. You may also be given specific stretches and exercises to do at work. Our therapist may visit your work place to analyze your job site and to watch how you do your job tasks. Afterward, we can recommend changes to help you do your job with less strain and less chance of injury. These changes are usually inexpensive and can make a big difference in helping you be more productive with less risk of pain or injury.

At FIT4YOU Physiotherapy, our goal is to help you understand your condition, to look for and change factors that may be causing your symptoms, and to help you learn how to avoid future problems. When your recovery is well underway, regular visits to our office will end. Although we will continue to be a resource, you will be in charge of practicing the strategies and exercises you’ve learned as part of an ongoing home program.

Surgery is rarely indicated for CTD. Specific conditions that can occur as a result of CTD may require surgery. Unless the doctor is quite sure there is a structural problem, such as a pinched nerve or severely inflamed tendon, then surgery is not usually suggested.

A rise in the use of magnetic resonance imaging (MRI) has led to the discovery that many people, perhaps as many as 15 percent of Americans, have a thoracic disc herniation. Seeing a herniated thoracic disc on MRI is often incidental, meaning it shows up when the person has MRI testing for another problem.

Few people with a thoracic disc herniation feel any symptoms or have any problems as a result of this condition. In rare cases when symptoms do arise, the main concern is whether the herniated disc is affecting the spinal cord.

Although people often refer to a thoracic disc herniation as a slipped disc, the disc doesn’t actually slip out of place. Rather, the term herniation means that the material in the center of the disc has squeezed out of the normal space. In the thoracic spine, this condition mostly affects people between 40 and 60 years old.

This guide will help you understand

Thoracic Disc Herniation

What parts of the spine are involved?

The human spine is formed by 24 spinal bones, called vertebrae. Vertebrae are stacked on top of one another to create the spinal column . The main section of each vertebra is a round block of bone, called the vertebral body.

The thoracic  spine is made up of the middle 12 vertebrae. Doctors often refer to these vertebrae as T1 to T12. The thoracic spine starts at the base of the neck. The lowest vertebra of the thoracic spine, T12, connects below the bottom of the rib cage to the first vertebra of the lumbar spine, called L1.

The upper half of the thoracic spine is much less mobile than the lower section, making disc herniations in the upper thoracic spine rare. About 75 percent of thoracic disc herniations occur from T8 to T12, with the majority affecting T11 and T12.

The intervertebral disc is a specialized connective tissue structure that separates the vertebral bodies. The disc is made of  two parts, The center, called the nucleus, is spongy. It provides most of the disc’s ability to absorb shock. The nucleus is held in place by the annulus, a series of ligament rings surrounding it. Ligaments are strong connective tissues that attach bones to other bones.

Healthy discs work like shock absorbers to cushion the spine. They protect the spine against the daily pull of gravity and during activities that put strong force on the spine, such as jumping, running, and lifting.

The spinal canal is a hollow tube inside the spinal column. It surrounds the spinal cord as it passes through the spine. The spinal cord is similar to a long wire made up of millions of nerve fibers. Just as the skull protects the brain, the bones of the spinal column protect the spinal cord. The spinal canal is narrow in the thoracic spine. Any condition that takes up extra space inside this canal can injure the spinal cord.

Blood vessels that run up and down the spine nourish the spinal cord. However, only one vessel, the anterior spinal artery, goes to the front of the spinal cord in the area between T4 and T9. Doctors call this section of the spine the critical zone. If this single vessel is damaged, as can happen with pressure from a herniated thoracic disc, the spinal cord has no other way to get blood. Left untreated, this section of the spinal cord dies, which can lead to severe problems of weakness or paralysis below the waist.

Why do I have this problem?

Thoracic disc herniations are mainly caused by wear and tear in the disc. This wear and tear is known as degeneration. As a disc’s annulus ages, it tends to crack and tear. These injuries are repaired with scar tissue. Over time the annulus weakens, and the nucleus may squeeze (herniate) through the damaged annulus. Spine degeneration is common in T11 and T12. T12 is where the thoracic and lumbar spine meet. This link is subject to forces from daily activity, such as bending and twisting, which lead to degeneration. Not surprisingly, most thoracic disc herniations occur in this area.

Less commonly, a thoracic disc may herniate suddenly (an acute injury). A thoracic disc may herniate during a car accident or a fall. A thoracic disc may also herniate as a result of a sudden and forceful twist of the mid-back.

Diseases of the thoracic spine may lead to thoracic disc herniation. Patients with Scheuermann’s disease, for example, are more likely to suffer thoracic disc herniations. It appears these patients often have more than one herniated disc, though the evidence is not conclusive.

Related Document: A Patient’s Guide to Scheuermann’s Disease

The spinal cord may be injured when a thoracic disc herniates. The spinal canal of the thoracic spine is narrow, so the spinal cord is immediately in danger from anything that takes up space inside the canal. Most disc herniations in the thoracic spine squeeze straight back, rather than deflecting off to either side. As a result, the disc material is often pushed directly toward the spinal cord. A herniated disc can cut off the blood supply to the spinal cord. Discs that herniate into the critical zone of the thoracic spine (T4 to T9) can shut off blood from the one and only blood vessel going to the front of the spinal cord in this section of the spine. This can cause the nerve tissues in the spinal cord to die, leading to severe problems of weakness or paralysis in the legs.

What does the condition feel like?

Symptoms of thoracic disc herniation vary widely. Symptoms depend on where and how big the disc herniation is, where it is pressing, and whether the spinal cord has been damaged.

Pain is usually the first symptom. The pain may be centered over the injured disc but may spread to one or both sides of the mid-back. Also, patients commonly feel a band of pain that goes around the front of the chest. Patients may eventually report sensations of pins, needles, and numbness. Others say their leg or arm muscles feel weak. Disc material that presses against the spinal cord can also cause changes in bowel and bladder function.

Disc herniations can affect areas away from the spine. Herniations in the upper part of the thoracic spine can radiate pain and other sensations into one or both arms. If the herniation occurs in the middle of the thoracic spine, pain can radiate to the abdominal or chest area, mimicking heart problems. A lower thoracic disc herniation can cause pain in the groin or lower limbs and can mimic kidney pain.

How do doctors diagnose the problem?

Diagnosis begins with a complete history and physical examination. Your doctor will ask questions about your symptoms and how your problem is affecting your daily activities. These include questions about where you feel pain, if you have numbness or weakness in your arms or legs, and if you are having any problems with bowel or bladder function. Your doctor will also want to know what positions or activities make your symptoms worse or better.

Then the doctor examines you to see which back movements cause pain or other symptoms. Your skin sensation, muscle strength, and reflexes are also tested.

X-rays show the bones. They normally don’t show the discs, unless one or more of the discs have calcified. This is significant in the diagnosis of thoracic disc herniation. A calcified disc that appears on X-ray to poke into the spinal canal is a fairlyreliable sign that the disc has herniated. It isn’t clear why a problem thoracic disc sometimes hardens from calcification, though past injury of the disc is one possibility.

The best way to diagnose a herniated thoracic disc is with magnetic resonance imaging (MRI). The MRI machine uses magnetic waves rather than X-rays to show the soft tissues of the body. It gives a clear picture of the discs and whether one has herniated. This machine creates pictures that look like slices of the area your doctor is interested in. The test does not require dye or a needle. This test has shown doctors that many people without symptoms have thoracic disc herniations. This has led some doctors to suggest that thoracic disc herniations not causing symptoms are normal.

Before MRI, doctors relied mainly on myelography to diagnose thoracic disc herniations. By itself, myelography only helps diagnose this condition in about half the cases. Myelography is a kind of X-ray test. A special dye is injected into the space around the spinal canal. The dye shows up on an X-ray. It helps a doctor see if the disc is pushing into the spinal canal.

Computed tomography (CT scan) may be ordered. This is a detailed X-ray that lets doctors see the body’s tissue in images that also look like slices. The images provide more information about calcified discs. Doctors may combine the CT scan with myelography. When the CT scan is performed, the myelography dye highlights the spinal cord and nerves. The dye can improve the accuracy of a standard CT scan for diagnosing a herniated thoracic disc.

Doctors rely mostly on MRI for diagnosing thoracic disc herniations. However, they may use myelography and CT scans when preparing to do surgery to fix a herniated thoracic disc.

What treatment options are available?

Nonsurgical Treatment

Doctors closely monitor patients with symptoms from a thoracic disc herniation, even when the size of the herniation is small. If the disc starts to put pressure on the spinal cord or on the blood vessels going to the spinal cord, severe neurological symptoms can develop rapidly. In these cases, surgery is needed right away. However, unless your condition is affecting the spinal cord or is rapidly getting worse, most doctors will begin with nonsurgical treatment.

At first, your doctor may recommend immobilizing your back. Keeping the back still for a short time can calm inflammation and pain. This might include one to two days of bed rest, since lying on your back can take pressure off sore discs and nerves. However, most doctors advise against strict bed rest and prefer their patients do ordinary activities, using pain to gauge how much activity is too much. Another option for immobilizing the back is a back support brace worn for up to one week.

Doctors prescribe certain types of medication for patients with thoracic disc herniation. Patients may be prescribed anti-inflammatory medications such as aspirin or ibuprofen. Muscle relaxants may be prescribed if the back muscles are in spasm. Pain that spreads into the arms or legs is sometimes relieved with oral steroids taken in tapering dosages.

Your doctor will probably have a physical therapist direct your rehabilitation program. Therapy treatments focus on relieving pain, improving back movement, and fostering healthy posture. A therapist can design a rehabilitation program for your condition that helps you prevent future problems.

Most people with a herniated thoracic disc get better without surgery. Doctors usually have their patients try nonoperative treatment for at least six weeks before considering surgery.

Surgeons may recommend surgery if patients aren’t getting better with nonsurgical treatment, or if the problem is becoming more severe.

When there are signs that the herniated disc is affecting the spinal cord, surgery may be required, sometimes right away. The signs surgeons watch for when reaching this decision include weakening in the arm or leg muscles, pain that won’t ease up, and problems with the bowels or bladder.

Surgical treatment for this condition includes

• costotransversectomy and discectomy
• transthoracic decompression
• video assisted thoracoscopy surgery (VATS)
• fusion

Costotransversectomy

Surgeons use costotransversectomy to open a window through the bones that cover the injured disc. Operating from the back of the spine, the surgeon takes out a small section on the end of two or more ribs where they connect to the spine. (Costo means rib.) Then the bony knob on the side of the vertebra (the transverse process) is removed. (Ectomy means to remove.) This opens a space for the surgeon to work. The injured portion of the disc that is pressing against the spinal cord is removed (discectomy) with small instruments. Surgeons take extreme care not to harm the spinal cord.

Transthoracic Decompression

Transthoracic describes the approach used by the surgeon. Trans means across or through. The thoracic region is the chest. So in transthoracic decompression, the surgeon operates through the chest cavity to reach the injured disc. This approach gives the surgeon a clear view of the disc.

With the patient on his or her side, the surgeon cuts a small opening through the ribs on the side of the thorax (the chest). Instruments are placed through the opening, and the herniated part of the disc is taken out. This takes pressure off the spinal cord (decompression).

Video Assisted Thoracoscopy Surgery (VATS)

Recent developments in thoracic surgery include video assisted thoracoscopy surgery (VATS). This procedure is done with a thoracoscope, a tiny television camera that can be inserted into the side of the thorax through a small incision. The camera allows the surgeon to see the area where he or she is working on a TV screen. Small incisions give passage for other instruments used during the surgery. The surgeon watches the TV screen while cutting and removing damaged portions of the disc.

Categorized as minimally invasive surgery, VATS is thought to be less taxing on patients. Advocates also believe that this type of surgery is easier to perform, prevents scarring around the nerves and joints, and helps patients recover more quickly.

Fusion

After removing part or all of the disc, the spine may be loose and unstable. Fusion surgery may be needed immediately afterward. The medical term for fusion is arthrodesis. This procedure locks the vertebrae in place and stops movement between the vertebrae. This steadies the bones and can ease pain. Fusion surgery is not usually needed if only a small amount of bone and disc material was removed during surgery to fix a herniated thoracic disc.

In this procedure, the surgeon lays small grafts of bone over or between the loose spinal bones. Surgeons may use a combination of screws, cables, and rods to prevent the vertebrae from moving and allow the graft to heal.

What should I expect as I recover?

Nonsurgical Rehabilitation

Even if you don’t need surgery, your doctor may recommend that you work with a physical therapist. Patients are normally seen a few times each week for four to six weeks.

The first goals of treatment are to control symptoms, find positions that ease pain, and teach you how to keep your spine safe during routine activities.

As patients recover, they gradually advance in a series of strengthening exercises. Aerobic exercises, such as walking or swimming, can ease pain and improve endurance.

After Surgery

Rehabilitation after surgery is more complex. Some patients leave the hospital shortly after surgery. However, some surgeries require patients to stay in the hospital for a few days. Patients who stay in the hospital may be visited by a physical therapist soon after surgery. The treatment sessions help patients learn to move and do routine activities without putting extra strain on the back.

During recovery from surgery, patients should follow their surgeon’s instructions about wearing a back brace or support belt. They should be cautious about overdoing activities in the first few weeks after surgery.

Many surgical patients need physical therapy outside of the hospital. They see a therapist for one to three months, depending on the type of surgery. At first, therapists may use treatments such as heat or ice, electrical stimulation, massage, and ultrasound to calm pain and muscle spasm. Then they teach patients how to move safely with the least strain on the healing back.

As patients recover, they gradually begin doing flexibility exercises for the hips and shoulders, and mobility and strengthening exercises to address the back muscles. Patients may also work with the therapist in a pool. Patients progress with exercises to improve endurance, muscle strength, and body alignment.

As the rehabilitation program evolves, patients do more challenging exercises. The goal is to safely advance strength and function.

Ideally, patients are able to go back to their previous activities. However, some patients may need to modify their activities to avoid future problems.

When treatment is well under way, regular visits to the therapist’s office will end. The therapist will continue to be a resource, but patients will be in charge of doing their exercises as part of an ongoing home program.
