Objective: To provide anatomical base for the reseach of reparation reestablish of palm vassular and nervous injury. Methods: 30 palms were dissected. Each palm was respectively divided into 20 regions by the 5 transverse lines and the 4 longitudinal lines of the palm. And then the distribution of total palmar digital nerves (TPDN) and total palmar digital artery (TPDA) were observed. Results: The 1st and the 2nd TPDN started from lower inner quadrant of the 4th region. The 1st and the 2nd and the 3rd TPDA started from the 7th and the 8th region nearby C line , the 5th TPDA started from lower inner quadrant of the 8th region. The 1th and the 2 nd TPDN were ridden by the superficial palmar arch at the 7th region and divided into superior segment of arch and inferior segment of arch. The inferior segment of arch erupted digital nerves of median nerve respectively at the13th and the 14th region nearby D line. The 1st and the 2nd TPDA erupted propotional digital palmar arteries from a region of approximately 0.8-1.0cm to E line at the18th and the 19th region. The company path relationship of the 1st, the 2nd and the 3rd TPDN and digital nerve of median nerve and homonymous TPDA has 4 types: H1,H2,O and V. Conclusions: TPDN and TPDA have a characteristic distributing according to its region , which is useful for seeking and anastomosing the disconnected nerves of palm and for locating the block anaesthesia of palm nerve accurately.
