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.
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.
