Modified Bilateral V-Y Rotation Advancement Flap for Coverage of Fingertip Amputations.

Abstract

Background: The use of homodigital antegrade flow flaps is an appealing option for coverage of fingertip injuries with exposed bone as it provides good padding, sensation and colour match with no need for splinting or secondary procedure for flap separation. V-Y flaps presented by Atasoy and Kutler have limited ability of distal advancement. We used two separate V flaps each based on a separate neuro-vascular bundle to allow better advancement while keeping good vascularity and sensation. Methods: We used a modified bilateral V-Y rotation advancement flap for coverage of fourteen fingertip injuries with bone exposed in 11 adult patients. Time to complete healing and return to work was recorded. Range of motion of injured finger as well as fingertip sensation using two-point discrimination were assessed and compared to non-injured contralateral finger 6 months after surgery. Fingertip hypersensitivity, cold intolerance and hooked nail deformity were assessed as well. Results: All flaps survived, and all patients resumed their activities after a mean period of 5 weeks. The mean two-point discrimination was 3.9 mm and was comparable to non-injured side. All patients regained full range of motion and were satisfied by the result. Two cases suffered from hypersensitivity that resolved at 3 months post-operative. Hooked nail deformity and cold intolerance were not recorded in our study. Conclusions: This modified bilateral V-Y rotation advancement flap technique presents a simple and single step procedure that provides good padding of fingertip with cosmetically pleasant contour and normal sensation. Level of Evidence: Level IV (Therapeutic).
