The Anatomy of the Biceps Pulley
- 657 Downloads
The pulley has recently been described as a structure that aids in the prevention of biceps instability. The biceps pulley or “sling” is a capsule ligamentous complex that acts to stabilize the long head of the biceps tendon in the bicipital groove. The pulley complex is composed of the superior glenohumeral ligament, the coracohumeral ligament, and the distal attachment of the subscapularis tendon and is located within the rotator interval between the anterior edge of the supraspinatus tendon and the superior edge of the subscapularis tendon.
The interest in the pulley lesions has increased in recent times, due to the biceps instability it could generate. A better understanding of the anatomy, functions, and subsequently pathology of the pulley can help to treat the patients in a more effective manner for the biceps pathology but also for all the other pathologic conditions associated with the pulley lesions, like anterosuperior impingement, superior labrum anterior, and posterior lesions.
