Cadaveric dissection study of 63 shoulder specimens defining the anatomy of the coracohumeral ligament — its origin, insertion variants, and mechanical contribution to external rotation — to clarify conflicting prior descriptions and establish the anatomic basis for its release in shoulder pathology.
When you encounter a stiff shoulder with disproportionate loss of external rotation — at rest or intraoperatively during arthroplasty or rotator cuff repair — the coracohumeral ligament is a primary culprit: release it at its coracoid origin (not the variable insertion) to avoid cuff injury and preserve tissue for repair.
