Anatomical Relations

The coracohumeral ligament attaches to the dorsolateral base of the coracoid process. The ligament extends laterally to the greater and lesser tubercles of the humerus. It blends superiorly with the articular capsule and the tendon of supraspinatus muscle, and inferiorly with the superior glenohumeral ligament. The coracohumeral ligament forms a portion of the tunnel of the biceps brachii tendon, which separates the ligament into two bands and giving it a V-shaped appearance.

Function

The coracohumeral ligament reinforces the articular capsule of the glenohumeral joint. Additionally, it plays a role in stabilizing the glenohumeral joint, preventing superior or inferior dislocation of the humeral head during lateral rotation (Itoi et al., 1998).
