The arterial supply of the clavicle.

This report based on delineation of the arterial system with 3 component plastic material on 10 human cadavers describes the arterial supply to the clavicle. The study was performed in 2 parts. One part, which showed the total arterial supply to the clavicle and one part with selective injections of the relevant arteries, with the intention of finding a central nutrient arterial supply to the clavicle. Three arteries were found to supply the clavicle: the suprascapular a.; the thoracoacromial a.; and the internal thoracic (mammary) a. The main supply was primarily periosteal. No nutrient artery was found.
