From: Anatomical study for the treatment of proximal humeral fracture through the medial approach
Inferior aspect of axilla (Right) (P: proximal D: distal M: medial L: lateral). CT: Conjoint tendon of the latissimus dorsi and teres major muscles; ACHA: Anterior circumflex humeral artery; PCHA: Posterior circumflex humeral artery; MCN: Musculocutaneous nerve; CB: Coracobrachialis. Structures at risk: ACHA, PCHA, musculocutaneous nerve. The interval between ACHA and PCHA is the area that suitable for the placement of the medial plate
