The rotator cuff consists of four muscles which stabilize the shoulder joint. These muscles are the subscapularis, supraspinatus, infraspinatus, and teres minor. They hold the ‘ball-shaped’ head of the humerus bone in the socket of the scapula. These muscles arise from the scapula and connect directly into the head of the humerus bone. The glenohumeral joint is similar to a golf ball sitting on a golf tee. When the arm is elevated, the rotator cuff compresses the glenohumeral joint in order to allow the large deltoid muscle to further elevate the arm.
