- coracoid process can be palpated thru anterior deltoid muscle one to two finger breadths below outer portion of clavicle;
- one finger breadth lateral to coracoid is the GHJ;
- provides a palpable guide to deltopectoral groove;
- serves as an anchor for coracoid muscles (coracobrachialis & short head of biceps) that separate lateral safe side from medial side where brachial plexus and vessels lie;
- clavipectoral fascia covers the floor of deltopectoral groove and is identified by rotating humerus;
- this allows subscapularis to be identified beneath fascial layer;
Role of CA Ligament:
- attaches to front and undersurface of acromion as a thick band and continues around anterolateral corner to attach to lateral ridge for a variable distance.
- anteriorly, the coracoacromial ligament attaches to the anterior inferior edge of the acromion, while the deltoid fascia attaches more superiorly;
- up to 15 mm of motion may occur between the acromion and the coracoid, when subjected to a 30 kg distractive force;
