WHATS INVOLVED IN A TORN ROTATOR CUFF?
The rotator cuff is a set of four muscles that motor the shoulder joint. These muscles originate from the shoulder blade (scapula) and turn into fibrous tendons as they approach the outer aspect of the shoulder. These four tendons surround the front, top, and back of the shoulder joint. When the rotator cuff muscles contract, they pull on the rotator cuff tendons, allowing the shoulder to move through a wide range of motion.
