To provide sensation to the reverse digital artery (RDA) flap, both the dorsal branch from the proper digital nerve and the superficial sensory branch from the corresponding radial or ulnar nerve are sectioned at their proximal ends and included with the RDA flap. These are then anastomosed with the distal ends of both radial and ulnar digital nerves at the recipient wound. Three cases of pulp defects reconstructed by this technique achieved very favourable functional and cosmetic results. The RDA flap, innervated through bilateral neurorrhaphy, seems to be an excellent option for one-stage reconstruction of major pulp defects.
为使逆行指动脉（RDA）皮瓣获得感觉，将指固有神经的背侧支和相应桡神经或尺神经的浅感觉支在其近端切断，并包含在RDA皮瓣内。然后将它们与受区伤口处的桡、尺指神经远端进行吻合。采用该技术重建3例指腹缺损，获得了非常满意的功能和美容效果。通过双侧神经缝合进行神经支配的RDA皮瓣似乎是一期重建严重指腹缺损的极佳选择。
