Coracohumeral Ligament

The CHL originates on the dorsolateral base of the coracoid process and blends with the capsule to the greater and lesser tuberosities. The CHL is present in more than 90% of individuals, and it runs parallel to the SGHL, blending with the superior border of the SGHL inferiorly. Portions of the CHL form the tunnel for the biceps tendon on the anterior side of the joint, and reinforces the RTI. In addition, the CHL reinforces the supraspinatus and infraspinatus tendon insertions as the RTC cablE.

The CHL has been reported to have multiple functions, limiting external rotation in the adducted arm as well as inferior translation and preventing anterosuperior migration of the humeral head. In a study of 11 cadaveric specimens that tested the static restraints of the GH joint, however, found that the CHL does not play a suspensory role.
