Osteonecrosis of the Humeral Head

Osteonecrosis of the Humeral Head

Osteonecrosis of the humeral head is a condition where a portion of the bone of the humeral head (the top of the humerus or upper arm bone) loses its blood supply, dies and collapses. Another term used for osteonecrosis is avascular necrosis. The term avascular means that a loss of blood supply to the area is the cause of the problem and necrosis means death.This condition has been reported in all age groups but seems more common between the ages of 20 and 50. Men are affected by osteonecrosis o...
Guide to Biceps Tendonitis

Guide to Biceps Tendonitis

Biceps tendonitis, also called bicipital tendonitis, is inflammation of the tendon that attaches the biceps muscle to the shoulder or forearm. The tendon most commonly irritated is the one that attaches the top of the biceps muscle to the shoulder, so it is this injury that we will discuss here. The most common cause of biceps tendonitis is overuse from certain types of work or sports activities. Biceps tendonitis may develop gradually from the effects of wear and tear, or it can happen suddenly...
Adhesive Capsulitis Patient Guide

Adhesive Capsulitis Patient Guide

Many adults (mostly women) between the ages of 40 and 60 years of age develop shoulder pain and stiffness called adhesive capsulitis. You may be more familiar with the term frozen shoulder to describe this condition. Frozen shoulder and adhesive capsulitis are actually two separate conditions.
Calcific Tendonitis of the Shoulder Patient Guide

Calcific Tendonitis of the Shoulder Patient Guide

Calcific tendonitis of the shoulder happens when calcium deposits form on the tendons of your shoulder. The tissues around the deposit can become inflamed, causing a great deal of shoulder pain. This condition is fairly common. It most often affects people over the age of 40.
Weightlifters Shoulder

Weightlifters Shoulder

Weightlifter's shoulder is a painful deterioration of the distal end of the clavicle (collar bone). It is an overuse phenomenon that causes tiny fractures along the end of the clavicle and then a breakdown of the bone (osteolysis) occurs.
Shoulder Dislocations

Shoulder Dislocations

A shoulder dislocation is a painful and disabling injury of the glenohumeral joint. Most dislocations are anterior (forward) but the shoulder can also dislocate posteriorly (backwards). Inferior and posterolateral dislocations are possible but occur much less often. The specific type of dislocation is based on the position of the humeral head in relation to the glenoid (shoulder socket) at the time of the diagnosis.
Adult Shoulder Fractures

Adult Shoulder Fractures

The shoulder is a region of the body rather than a bone or even a joint. Doctors refer to this area collectively as the shoulder girdle. There are four bones and three joints in the region. Injury to any one of them may be considered a shoulder fracture or dislocation and all affect the function of the shoulder and arm.The overall function of the shoulder is to provide a secure base for the movements of the arm. The base must be strong to bear the load when you lift something and mobile enough t...
Adult Humerus Fractures

Adult Humerus Fractures

The humerus goes from the shoulder joint to the elbow joint and must be strong enough to take a good deal of weight when you lift something or push against something. It is one of the big three bones of the body. Only the femur (thighbone) and the tibia (shinbone) are bigger and stronger. Without a functioning humerus you cannot position the hand in space or use the elbow.
Quadrilateral Space Syndrome

Quadrilateral Space Syndrome

Quadrilateral space syndrome (QSS) happens when the axillary nerve is compressed, or injured in the back of the shoulder. Sometimes the symptoms are caused by the compression of an artery in the same area.
Rotator Cuff Tears

Rotator Cuff Tears

The shoulder is an elegant and complex piece of machinery. Its design allows us to reach and use our hands in many different positions. However, while the shoulder joint has great range of motion, it is not very stable. This makes the shoulder vulnerable to problems if any of its parts aren't in good working order.
Thoracic Outlet Syndrome

Thoracic Outlet Syndrome

Thoracic outlet syndrome (TOS) can cause pain and numbness in the shoulder, arm, and hand. Testing for TOS is difficult. There is no one test to accurately diagnose TOS, and other conditions can have similar symptoms. You will need to go through several tests to find out if TOS is actually the cause of your pain. Making the right diagnosis often takes time and can be a cause of frustration, both for you and your doctor.
Sternoclavicular Joint Problems

Sternoclavicular Joint Problems

The sternoclavicular (SC) joint is important because it helps support the shoulder. The SC joint links the bones of the arms and shoulder to the vertical skeleton.
Snapping Scapula Syndrome

Snapping Scapula Syndrome

The scapulothoracic joint is located where the shoulder blade (also called the scapula) glides along the chest wall (the thorax). When movement of this joint causes feelings or sounds of grating, grinding, popping, or thumping, doctors call it snapping scapula syndrome.
Shoulder Instability

Shoulder Instability

Shoulder instability means that the shoulder joint is too loose and is able to slide around too much in the socket. In some cases, the unstable shoulder actually slips out of the socket. If the shoulder slips completely out of the socket, it has become dislocated. If not treated, instability can lead to arthritis of the shoulder joint.
Osteoarthritis of the Acromioclavicular Joint

Osteoarthritis of the Acromioclavicular Joint

Some joints in the body are more likely to develop problems from normal wear and tear. Degeneration causes the cartilage that cushions the joint to wear out. This type of arthritis is called osteoarthritis. Doctors sometimes refer to this type of arthritis as arthrosis.
Labral Tears

Labral Tears

Since orthopedic surgeons began using a tiny TV camera called an arthroscope to diagnose and treat shoulder problems, they have discovered several conditions that no one knew existed. One of these conditions is an injury to a small structure in the shoulder called the labrum. A labral tear can cause pain and a catching sensation in the shoulder. Labral tears can be very difficult to diagnose.
Impingement Syndrome

Impingement Syndrome

The shoulder is a very complex piece of machinery. Its elegant design gives the shoulder joint great range of motion, but not much stability. As long as all the parts are in good working order, the shoulder can move freely and painlessly.
Calcific Tendonitis of the Shoulder

Calcific Tendonitis of the Shoulder

Calcific tendonitis of the shoulder happens when calcium deposits form on the tendons of your shoulder. The tissues around the deposit can become inflamed, causing a great deal of shoulder pain. This condition is fairly common. It most often affects people over the age of 40.
Biceps Rupture

Biceps Rupture

A biceps rupture involves a complete tear of the main tendon that attaches the top of the biceps muscle to the shoulder. It happens most often in middle-aged people and is usually due to years of wear and tear on the shoulder. A torn biceps in younger athletes sometimes occurs during weightlifting or from actions that cause a sudden load on the arm, such as hard fall with the arm outstretched.
Acromioclavicular Joint Separation

Acromioclavicular Joint Separation

A shoulder separation is a fairly common injury, especially in certain sports. Most shoulder separations are actually injuries to the acromioclavicular (AC) joint. The AC joint is the connection between the scapula (shoulder blade) and the clavicle (collarbone). Shoulder dislocations and AC joint separations are often mistaken for each other. But they are very different injuries.
