When Not to Have Rotator Cuff Surgery
The rotator cuff is the group of muscles and tendons that surround the ball-and-socket shoulder joint. It is comprised of several muscles and three shoulder joint bones: the humerus, scapula, and clavicle. When a rotator cuff tears, one of the tendons connected to the head of the humerus is either partially or completely detached.
