The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.
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.
