The supraspinatus (plural supraspinati, from Latin supraspinatus) is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder.
The rotator cuff also holds your upper arm bone in place in your shoulder socket. The four muscles of the rotator cuff are the supraspinatus, the infraspinatus, the teres minor and the subscapularis. Each muscle is connected to the arm bone by a tendon. Rotator cuff repair is the surgery used to repair a tear in one of these tendons.
