Rotator Cuff

  Sometimes mistakenly thought to mean bones in the shoulder, the Rotator Cuff actually consists of 4 muscles which help maintain shoulder mobility, stability, & function.

These muscles are called the “S.I.T.S.” muscles, an acronym for the 4 components---the Supraspinatous, Infraspinatous, Teres minor, and Subscapularis muscles.

Of these 4, the Supraspinatous is most commonly injured. It attaches across the top of the scapula to the top of the humerus, the upper bone of the arm. “Swimmer’s shoulder” is an injury to the Supraspinatous tendon, caused by repetitive forceful adduction of the arm against the resistance of the water.
