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.
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.
