Abstract

The rotator cuff interval can be found in the anterior superior aspect of the glenohumeral joint between the supraspinatus and subscapularis muscles. It consists of the coracohumeral ligament , superior and middle glenohumeral ligaments, long head of the biceps, and corresponding shoulder capsule. It is not only an important landmark for arthroscopy and surgical entry into the shoulder but also a critical anatomic structure in adhesive capsulitis and instability pathology. The coracohumeral ligament, the focus of this chapter, is the most superficial of the rotator interval components and blends its fibers with the other components of the rotator interval to create a multidirectional support sling that keeps the humeral head elevated and resists external rotation. For this reason, when the coracohumeral ligament and rotator interval becomes contracted, as in adhesive capsulitis, the humeral head elevates and loses external rotation; when they are patulous and incompetent, the biceps tendon and glenohumeral joint develop instability.
