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. The most common causes of nontraumatic shoulder pain in descending order of frequency are rotator cuff tendinopathy, acromioclavicular joint disease, adhesive capsulitis, and referred pain.1
