ABSTRACT
Background: Injury to the axillary nerve has devastating results. Variations in the distance between the acromial edge and axillary nerve range from 20-70 mm. The purpose of this study was to anatomically analyze the relations between the anterior trunk of the axillary nerve and the acromion in order to provide guidelines for minimizing intraoperative iatrogenic neural injury. Methods: The distances between the axillary nerve and the posterolateral, midlateral , and anterolateral edges of the acromion were measured in 60 cadaveric shoulders (30 fresh cadavers). The correlations between these measurements to the weight, height and sex of the cadavers were statistically analyzed. Results: The distances between the axillary nerve and all three acromial anatomic landmarks significantly correlated with the cadaver’s height (p
