The digital defects which severely interfered with the hand functions must be reconstructed. The primary repair by vascularized skin flap with the dorsal branch of proper palmar digital nerve could be done. The vascularized flap was rich in blood circulation, perfect sensibility and a good contour, as well as preserving donor digital sensation. However, it was simple, safe, and with higher success. From 1989 to 1991, 10 cases of digital defects were treated, all of the patients gained very good results. The indication and technique of thismethod wasdiscussed in detail.
