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.
When those tendons are worn, torn, inflamed, or entirely ruptured, it hurts. The rotator cuff muscles act as tendons to hold the shoulder mechanism together with the arm. There are four of them, also known as the âSITSâ muscles: supraspinatus, infraspinatus, teres minor, serratus anterior.
