Anatomical study on supply of ulnar nerve in elbow region and anterior transposition of vascularized ulnarnerve for cubital tunnel syndrome

Objective To investigate the blood supply of the ulnar nerve in elbow region and design the procedure of anterior transposition of the vascularized ulnar nerve for cubltal tunnel syndrome.Methods The vascular of the ulnarnerve was studied and measured in 28 adult CadaVver upper limbspecimens.and the clinical surgical procedure was imitated in 4 adult cadaver upper limb specimens,Results There are three major arteries to supply the ulnar nerve at the elbow region:the superior ulnar collateral artery,the inferior ulnarcollateral artery and the posterior ulnar recurrent artery.The distances from arterial origin to the medial epicondyle were(15.2 ±0.9)cm,(4.8±0.6)cm,(4.7 ±1.1)cm respectively.And the total length of the vessels travelling alone with the course of the ulnar nerve were(16±1.3)cm,(5.1±0.3)cm and(5.6±0.9)cm respectively.Conclusion It is out of question to perform anterior transposition of the ulnar nerve wlth accompanying arteries for cubital tunnel syndrome.
