Background and objective.

Wounds with loss of substance in fingertips are one of the most frequent reasons for consultation in the emergency room. Treatment options are varied, and the choice will depend primarily on the injury pattern and topography. A technique that is indicated in cases of extensive substance loss is the reverse flow homodigital flap. This procedure is performed in one surgical time, provides good results, has a wide arc of rotation and offers stable coverage with good vascularization and acceptable sensory recovery.

The purpose of this paper is to show the authors experience in reconstruction of finger tip defects with homodigital flap in reverse flow.

Methods.

We present a series of 6 patients with finger tip wounds with loss of substance, operated by the authors in 2020, using a reverse flow homodigital flap performing resensitization using neurorraphy to the contralateral collateral nerve in 2 cases.

Results.

Patients were all male, most of them manual workers, with an age range from 20 to 38 years. They presented amputation at the zone II and III level of the fingers, transverse or oblique palmar, excluding the thumb. Preoperative plain radiographs showed involvement of the distal phalanx. The follow-up of the patients was 6 months. There were no complications. Regarding the flexion arc of the digits, all presented preserved mobility, with an acceptable sensory recovery.

Conclusions.

Our results are similar with international literature, regarding the advantages of this technique. This work shows our experience with this flap. We will continue collecting cases in order to increase the level of evidence.
