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 most common shoulder injury is to the rotator cuff. This includes sprains, strains and tears to the muscles in the rotator cuff. There are four muscle groups in this area of the shoulder. They are the supraspinatus, subscapularis, infraspinatus and teres minor. They work together to operate the movement in the shoulder. The supraspinatus tendon is one of the important muscles in this movement.
