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.
This is especially true of the supraspinatus muscle which is the most commonly torn rotator cuff muscle. When a tear occurs, the person typically has difficulty abducting their arm and often leans to the side in order to make it seem like their arm is abducting.Symptoms can include generalized shoulder pain. On the scapular end, the supraspinatus muscle attaches to a depression (fossa) on the top of the scapula that is technically called the supraspinous fossa. 2  On the other end it attaches onto the very top of the head of the humerus.
