The term rotator cuff describes the tendons connecting the infraspinatus, supraspinatus, teres minor, and subscapularis muscles to the humeral head.Traumatic tears of the rotator cuff tend to occur at the tendon-bone junction of the supraspinatus and greater tuberosity of the humerus whereas degenerative tears tend to be seen posteriorly at the junction of the supraspinatus and infraspinatu A rotator cuff tear is when one or more of these tendons tears or detaches from the humerus.
