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 rotator cuff also holds your upper arm bone in place in your shoulder socket. The four muscles of the rotator cuff are the supraspinatus, the infraspinatus, the teres minor and the subscapularis. Each muscle is connected to the arm bone by a tendon. Rotator cuff repair is the surgery used to repair a tear in one of these tendons.
