Rotator cuff tear such symptoms frequently are diagnosed with failed rotator cuff syndrome. According to an article published by the American Academy of Orthopaedic Surgeons, arthroscopic procedures produce "satisfactory results" more than 90 percent of the time. Dr. Eric J. Strauss and the other authors wrote that 6-8 percent of patients have "incompetent" rotator cuffs, because their repaired tendons either fail to heal or develop additional tears. In some cases, the symptoms are due to cervical spine disease, featuring neck pain that radiates into the shoulder; suprascapular neuropathy, a nerve disorder; subacromial impingement, common in athletes and others who make repetitive overhead movements;
Rotator cuff is divided from the remainder of the rotator cuff origins as it is deep to the scapula. The four tendons of these muscles converge to form the rotator cuff tendon. These tendinous insertions along with the articular capsule, the coracohumeral ligament, and the glenohumeral ligament complex, blend into a confluent sheet before insertion into the humeral tuberosities. The insertion site of the rotator cuff tendon at the greater tuberosity is often referred to as the footprint. The infraspinatus and teres minor fuse near their musculotendinous junctions, while the supraspinatus and subscapularis tendons join as a sheath that surrounds the biceps
