Shoulder of the rotator cuff are supraspinatus, subscapularis, infraspinatus, and teres minor. The cuff adheres to the glenohumeral capsule and attaches to the humeral head. The shoulder must be mobile enough for the wide range actions of the arms and hands, but stable enough to allow for actions such as lifting, pushing, and pulling. The shoulder consists of a ball-and-socket joint formed by the humerus and scapula and their surrounding structures - ligaments, muscles, tendons - which support the bones and maintain the relationship of one to another. These supporting structures attach to the clavicle, humerus, and scapula, the latter providing
Rotator cuff tear or arthritis. Superior labral anterior-posterior lesions produce pain similar to that of rotator cuff tears. Those most prone to failed rotator cuff syndrome are patients 65 years of age or older; and those with large, sustained tears. Smokers, diabetes sufferers, patients with muscle atrophy and/or fatty infiltration, and those who do not follow postoperative-care recommendations also are at greater risk. Doctors examine patients and conduct imaging tests to identify the causes of continued discomfort. Depending upon the diagnosis, several treatment alternatives are available. They include revision repair, nonanatomic repair, tendon transfer and arthroplasty. When possible, surgeons make tension-free repairs in
