Apart from the terminal branches, the branches of the brachial artery in the arm are profunda brachii, superior ulnar collateral artery, inferior ulnar collateral artery, muscular branches to the surrounding muscles and a nutrient branch to the humerus [1].
The superior ulnar collateral artery arose from the distal part of the brachial artery whereas the inferior ulnar collateral branch arose from the proximal part of the ulnar artery in the arm instead of arising from the brachial artery [fig3].
The extrinsic vascular system is composed of epineural segmentally arranged vessels that originate at various points from the superior ulnar collateral, inferior ulnar collateral, and posterior ulnar recurrent arteries.
(5) Anterior transposition significantly decreases the potential for nerve compression/ tension during elbow flexion; however, the procedure itself may devascularize the nerve by interfering with the intraneural circulation-namely, elimination of existing multiple mesentery-like vessels, especially those originating from the inferior ulnar collateral artery.
In its further course the common trunk at the commencement of the radial groove gave the profunda brachii branch and it continued further down along with the ulnar nerve to end by giving superior and inferior ulnar collateral branches in the arm (Fig.
The latter coursed deep to biceps brachii muscle and lateral to the median nerve.The profunda brachii, superior and inferior ulnar collateral arteries were normal in their origin and course.
