The rotator cuff is a unique structure in the shoulder that is formed by four tendons. These four tendons attach to four muscles that help keep the shoulder stabilized in the shoulder socket and help rotate the upper arm inward and outward. If the rotator cuff is severely torn and is not repaired, a type of arthritis of the shoulder may develop over time, which is termed rotator cuff arthropathy. The prefix ‘arthro’ means joint and ‘pathy’ means disorder therefore in sim...
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...
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...
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.
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.
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.
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.
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.
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.
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.
