Passage of the axillary nerve (a) close to the glenoid labrum (gl). The closest point between the axillary nerve and the glenoid labrum was slightly medial to the most inferior point of the glenoid labrum. h - humeral head

The shortest distance between the anterolateral (AA) and posterolateral (PA) tips of acromion and the axillary nerve which was provided by deltoid-splitting approach through the anterior and posterior avascular raphes of the deltoid muscle.
