The coracoacromial arch and the clavipectoral fasc

The coracoid process

The surgeon comes to full appreciation of the value of such a lighthouse when it is lacking--for example, when re-exploring a shoulder for complications of a coracoid transfer procedure. The clavipectoral fascia covers the floor of the deltopectoral groove. Rotating the humerus enables the surgeon to identify the subscapularis moving beneath this fascial layer. Incising the fascia up to but not through the coracoacromial ligament preserves the stabilizing function of the coracoacromial arch.
