[Presentation of a new homodigital, countercurrent sensitive island flap].

The authors present new sensitive homodigital island flap which can be used to cover large finger pulp defects when classical techniques cannot be applied. An anatomical study consisting of the meticulous dissection of the branches and anastomoses of the digital arteries formed the basis for this new flap. The precise but safe surgical technique is described with the presentation of the first five clinical cases. The authors consider the following advantages of this flap: unrestricted coverage of large pulp defects, the flap is innervated after repair of the transposed digital nerve, tension is avoided allowing immediate mobilization. They also consider the disadvantages related to the necessary section of the digital nerve and artery. However the authors consider that the benefits outweight the disadvantages when compared with conventional techniques.
