Fig. 1From: Anatomical study for the treatment of proximal humeral fracture through the medial approachFront view of shoulders (Right) (P: proximal D: distal M: medial L: lateral). ACHA: Anterior circumflex humeral artery; PCHA: Posterior circumflex humeral artery; MCN: Musculocutaneous nerve; CB: Coracobrachialis. The conjoint tendon lies between the coracobrachialis and the brachial plexus. (The pectoralis major was removed for a better view). The distance from the coracoid process to the ACHA was measured. After conjoint tendon removed, the bone surface of proximal humerus is exposed.Back to article page
