Rotator Cuff Tear
A tear in one or more of the four muscles and tendons that stabilize the shoulder joint.
Full Definition
A rotator cuff tear is an injury involving one or more of the four muscles and their tendons that comprise the rotator cuff: supraspinatus, infraspinatus, teres minor, and subscapularis. These structures work together to stabilize the humeral head in the glenoid fossa and enable shoulder rotation and elevation. Tears can be partial-thickness or full-thickness and may result from acute trauma or degenerative changes. The supraspinatus tendon is most commonly affected. Symptoms include shoulder pain, weakness, and limited range of motion, particularly with overhead activities.
Usage
Usage note: Specify partial-thickness vs. full-thickness when known; avoid simply 'torn rotator cuff' in clinical documentation.
