Fenestrated Adipofascial Reverse Flap: A Modified Technique for the Reconstruction of Fingertip Amputations

Fingertip injuries can be treated in different ways, including shortening with primary closure, skin graft, and local or distant flaps. Several local flaps for the reconstruction of the amputated fingertip were described. We present our experience with a new concept of homodigital adipofascial reverse flap that avoids the second surgical stage and allows a complete and anatomically perfect reconstruction of nail bed, with preservation of the nail lamina.

Between March 2014 and February 2015, five patients with digital amputations (distally to the nail matrix) were treated using the Fenestrated Adipofascial Reverse (F.A.R.) flap. The patients were evaluated measuring 2-point discrimination (2PD) value and range of motion of the distal interphalangeal joint (DIP). Scar evaluation was performed using the Vancouver Scar Scale (VSS).

All the flaps completely survived. A normal nail grow has been observed in first two-three months of post operatory follow-up. Length of the digits was preserved and good aesthetic as functional outcome were archive. The F.A.R. flap provided excellent coverage of fingertip defects and preserved finger length. After 1 year of follow, the mean static 2PD value at the reconstructed finger was 4.2 mm (range 3-5 mm), reconstructed fingers' mean range of motion for the DIP joint was 78 degrees and the VSS score ranged from 0 to 2 (mean score: 0.6). No complications were reported.

F.A.R. flap is one of the most useful techniques in order to achieve all the goals in fingertip reconstruction.
