Coracohumeral Ligament As Observed From An Anterior Perspective

Description

Arising from the lateral border and base of the coracoid process, the coracohumeral ligament spans inferolaterally across the rotator interval to blend with the superior aspect of the glenohumeral capsule and the region of the greater and lesser tubercles of the proximal humerus. From an anterior perspective, the coracoid sits medial to the humeral head, while the clavicle and acromion arch superiorly to frame the superior joint line and acromioclavicular region. The glenoid fossa lies posteromedial to the humeral head, with the superior capsule and adjacent superior glenohumeral ligament territory visible deep to the coracohumeral fibers. Bony context extends to the upper ribs and thoracic vertebrae posteriorly. Clinically, this is the ligament surgeons and radiologists think about when discussing the rotator interval and restraint to inferior translation and external rotation in adduction, and it becomes a prime teaching landmark when comparing anterior shoulder stability mechanisms. Thickening and contracture of the coracohumeral ligament is a recognized feature of adhesive capsulitis, where capsular and interval fibrosis restricts external rotation early and can be targeted during arthroscopic capsular release. It matters. The same anterior relationship to the coracoid also orients the deltopectoral approach and helps explain why pathology in the long head of the biceps tendon and superior labrum is often discussed alongside rotator interval anatomy. Use this asset for gross anatomy and orthopedic modules on the shoulder, for sports medicine and radiology teaching files that correlate MR arthrography findings of the rotator interval, and for operative guides illustrating arthroscopic interval release, biceps tenodesis planning, or assessment of anterior-superior capsular integrity.
