Fig. 1From: First dorsal metacarpal artery flap with dorsal digital nerve with or without dorsal branch of the proper digital nerve produces comparable short-term sensory outcomesDiagram showing that the dorsal digital nerves (DDN) and the dorsal branches of the proper digital nerves (DBPDNs) dominate the dorsal skin sensation of the index finger proximal phalanx. The DDN arises from the superficial branch of the radial nerve (SBRN), and the DBPDNs originate from the proper digital nerves (PDNs). The first dorsal metacarpal artery (FDMA) dominates the dorsal skin nutrition of the index finger proximal phalanxBack to article page
