The combined ALT-groin flap for the mutilated and degloved hand

Abstract

Background: Degloving and mutilation of the hand is a rare but formidable challenge. When replantation is not possible, we rely on distant pedicled flaps. We present a technique using pedicled anterolateral thigh (ALT) and groin flaps to sandwich and resurface the degloved hand. The purpose of this study is to describe the rationale, indications, methods and outcomes of combined pedicled ALT and groin flap reconstruction of the degloved hand.

Methods: Five injuries were treated at this center between 2011 and 2014. Charts were retrospectively reviewed and outcomes evaluated. Four ALT-groin flaps were performed in a single stage for degloving, crush and combined injuries. In one case, partial necrosis of a tight groin flap necessitated secondary ALT coverage at a second stage.

Results: Flaps survived after division at 4 weeks, and venous congestion was not observed at any point. Debulking, syndactyly release and toe transfer followed reconstruction to enhance outcomes.

Conclusions: The combined ALT-groin flap is safe and feasible for the reconstruction of the degloved or mutilated hand when replantation is not an option. It is attractive for familiar donor anatomy, donor-site morbidity and the quantity and composition of the tissue it provides.
