Medical Definition of Rotator cuff

1. The rotator cuff is a tendon formed by three distinct muscles: teres minor, supraspinatus and infraspinatus, which stabilise the head of the humerus within the shoulder joint. Tendinitis or injury to the rotator cuff muscle can make shoulder abduction (lifting the arm out to the side) and external rotation painful. In most cases treatment includes rest, ice and physical therapy to strengthen the shoulder muscles. (13 Nov 1997)
