Objective: To investigate the elbow ulnar nerve accompanied feeding vessels , the blood supply of the deep fascia anterior medial ulnar nerve branches and elbows provide anatomical basis for the feasibility of bloody pre- surgery for ulnar nerve deep fascia flap . Methods: 6 ( 4 male , 2 female ) adult formalin the antiseptic treatment corpse 12 side cadavers , four ( three male , one female ) adult fresh cadavers side cadavers , anatomical observation elbow structure , find and observe the ulnar nerve branch and its blood supply , dependent role of blood vessels and nerves associated with line length and the vertical distance measured on the ulnar nerve . Simulated surgical operation on a fresh corpse , the ulnar nerve and its feeding vessels fully free , front , measuring the maximum distance of the ulnar nerve front . The anatomy of the elbow anteromedial Find relatively constant dependent the there deep fascia artery . Measurement tools as a ruler , accuracy to 0.1 cm. Results: ulnar nerve blood supply 3 : the ulnar on collateral artery ( SUCA ) , inferior ulnar collateral artery (IUCA) and ulnar recurrent artery branch ( PURA ) , accompanied with the ulnar nerve length of approximately 15.5 cm, 4.5 cm and 5.5 cm. Fully free of the ulnar nerve and dependent artery , the ulnar nerve blood supply to move forward at least 7cm . Ulnar nerve at the elbow issue articular branch and muscular branches were 1 to 3 . Elbow medial failed to find a constant dependent artery deep fascia there before . Conclusion: The front line ulnar nerve deep fascia flap surgery should be reserved at least SUCA or IUCA . The deep fascia flap production should be based on the principle of random flap .
