Fingertip reconstruction using two variations of direct-flow homodigital neurovascular island flaps.

The fingertip is an extremely intricate area of digital sensibility that plays an important role in fine perception and hand function. Thus, sensate fingertip reconstruction is essential to the recovery of most hand functions. The authors used two methods of direct-flow homodigital neurovascular island flap coverage to reconstruct distal finger amputations-namely, the triangular-advancement flap technique and the step-advancement flap method. The authors present their experience with these two variations of direct-flow homodigital neurovascular island flaps and their use in reconstructing 18 fingertips and 7 proximal amputation stumps. They did not observe flap failure, and they achieved stable, well-vascularized, appropriate-thickness skin coverage with good sensory properties in all patients. However, they found that the triangular-advancement flap technique was easier to plan and perform than the step-advancement method.
