Anatomical terminology

The coracohumeral ligament is a broad ligament of the shoulder. It strengthens the upper part of the joint capsule of the shoulder joint.

Structure[]

The coracohumeral ligament arises from the lateral border or the base of the coracoid process.[1][2] It passes obliquely downwards and laterally to the front of the greater tubercle of the humerus.[1][2] It lies above the head of the humerus.[2] It blends with the tendon of the supraspinatus muscle.[1] It also blends with the subscapularis muscle.[1] It has two bands, anterior and posterior, that insert into the lesser and greater tubercles of the humerus respectively.

This ligament is intimately united to the capsule by its posterior and lower border, but its anterior and upper border presents a free edge, which overlaps the capsule.

Function[]

The coracohumeral ligament strengthens the upper part of the joint capsule of the shoulder joint.[3]

Clinical significance[]

The coracohumeral ligament may be viewed using ultrasound of the shoulder.[4][5]
