Rotator Cuff Tear
The rotator cuff refers to the convergence of ligaments and tendons that encapsulate the glenohumeral joint, which consists of the articulation of the humeral head with the glenoid fossa of the shoulder blade (scapula). Since these ligaments and tendons are involved in moving your arm, they are subject to stress and tears.
If you have a minor rotator cuff strain or partial tear, it can heal on its own with proper rehabilitation. Larger or full thickness tears remain chronic (unjoined) after the acute phase has passed. For these, arthroscopic surgery to suture the tear is usually indicated.
