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.
A rotator cuff is comprised of four muscles (supraspinatus, infraspinatus, subscapularis, and teres minor) located in the shoulder area, which provide support to the shoulder joints. Any kind of rotator cuff injury, such as a subscapularis tear, can result in scapular pain.
