Treatment depends on the cause and can include physical therapy, injections of corticosteroids into the joint space or bursa, and surgery. This paper reviews the diagnosis and treatment of impingement syndrome, adhesive capsulitis, rotator cuff tears, and arthritis of the glenohumeral joint and acromioclavicular (AC) joint.
