The Rotator Cuff

Caption

A set of four muscles and their tendons attach to the ball of the humerus, forming what is called the rotator cuff. The cuff becomes susceptible to tears with age. Reattaching the tendon to the bone is difficult because the tendon and bone have very different biomechanical properties and stresses tend to localize along their interface.
