Reconstruction of multiple long digital and hand defects using the multilobed anterolateral thigh perforator flap.

Abstract

Objective: This study investigated the reconstruction of multiple long digital and hand defects using the multilobed anterolateral thigh perforator flap.

Methods: From January 2018 to January 2021, 14 patients (hands) with multiple long digital defects were treated using the multilobed anterolateral thigh perforator flap. The mean age of the patients was 35 years (range, 18-55 years). The mean size (length × width) of the defects was 12.3 × 10.6 cm (range, 9 × 7 cm-16 × 12 cm). The mean size of the flap was 13.7 × 12.1 cm (range, 11 × 8 cm-19 × 14 cm). The total active motion was compared to the opposite side (100% normal, excellent; 75%-99% normal, good; 50%-74% normal, fair; <50% normal, poor).

Results: In this series, 12 flaps survived completely. Partial flap necrosis occurred in 2 patients but healed with wound care. The mean follow-up period was 28 months (range, 25-34 months). Based on the total active motion scoring system, we got 1 excellent, 7 good, 7 fair, and 1 poor result. A second surgery to separate the digits was not required.

Conclusion: Multiple digital and hand defects can be reconstructed simultaneously using the multilobed anterolateral thigh perforator flap, allowing a length-to-width ratio of greater than 1.5:1 to resurface long digital defects.

Level of evidence: Level IV, Therapeutic Study.
