The shoulder consists of 2 bones (ie, humerus, scapula), 2 joints (ie, glenohumeral, acromioclavicular), and 2 articulations (ie, scapulothoracic, acromiohumeral). Several interconnecting ligaments and layers of muscles join these bones. The relative lack of bony stability in the shoulder permits a wide range of motion. Soft tissue structures are the major glenohumeral stabilizers.
