The shoulder has two joints, the acromioclavicular joint which connects the shoulder blade with the collar bone and the glenohumeral joints which connects the upper arm to the shoulder blade. Osteoarthritis most often affects the glenohumeral joint although either joint can be affected. A previous injury is a significant cause of this form of osteoarthritis or by the shoulder suffering any abnormal stresses. In other cases osteoarthritis becomes more common with increasing age. It is estimated that 20% of those over 65 have some form of shoulder osteoarthritis.
Signs and Symptoms of Shoulder Osteoarthritis.
Pain is the most common symptom, there may also be some limitation in the shoulder's range of movement. When moved, the shoulder may also make a clicking sound.
Diagnosing Shoulder Osteoarthritis.
When arriving at a diagnosis, doctors will normally look for the following:
An x-ray is also a standard part of diagnosis. X-rays will reveal any narrowing of joint space, any changes in bone structure and the presence of bony spurs (ostephytes) in the affected joint.
Treating Shoulder Arthritis.
The first stage of treatment consists of modifying current activities, rest and the application of ice. Physical therapy, strength training and aerobic exercise may help reduce the effect of the condition. Painkillers (Non-steroidal anti-inflamatory drugs and COX-2 inhibitors) are the standard drug treatments for pain although some advanced cases may require corticosteroid injections.
If none of the above are effective then joint replacment surgery may be offered although this is flt to be less successful in younger and more active patients.
