To meet the many demands placed on it, the shoulder uses three bones, four joints, and a specialized set of soft tissues consisting of muscles, tendons, ligaments, and bursae. Common causes of nontraumatic shoulder pain are subacromial impingement syndrome, rotator cuff tears, acromioclavicular joint disease, adhesive capsulitis, and referred pain.
