title: Homodigital artery flap reconstruction for fingertip amputation: a comparative study of the oblique triangular neurovascular advancement flap and the reverse digital artery island flap.
abstract: This fingertip reconstruction study retrospectively compared sensory recovery and active range of motion outcomes in neurovascular island advancement and reverse digital artery island flaps. Seventeen oblique triangular flaps and 14 reverse digital artery island flaps were performed for nail bed level fingertip amputations (Ishikawa subzone II). There was no significant difference between the two procedures in the Semmes-Weinstein monofilament test and range of motion results. For static and moving two-point discrimination tests, however, those with a reverse digital artery island flap required a longer period for sensory recovery compared to those with an oblique triangular advancement flap. This trend equilibrated at 12 months after surgery showing no significant difference in both static and moving two-point discrimination tests between the procedures.
