The rotator cuff muscles are the dynamic stabilizers and movers of the shoulder joint and adjust the position of the humeral head and scapula during shoulder movement. The rotator cuff muscles are anatomically associated with the scapula.
The rotator cuff is the most important group of muscles giving it support and stability allowing the shoulder to function through a wide range of motions. In part due to the rotator cuff, the shoulder joint can move and turn through a wider range than any other joint in the body. Patients with repetitive use injuries to the rotator cuff often have complaints of shoulder pain prior to developing a complete rotator cuff tear. 2  Traumatic Injuries: Traumatic injuries to the rotator cuff are seen after events such as throwing, golf and falling on to an outstretched arm.
