Composite anterolateral thigh perforator flaps in the management of complex hand injuries.

Abstract

The anterolateral thigh (ALT) fasciocutaneous flap has been well described for hand skin cover, however its use in its composite (multiple tissue) form incorporating bone, muscle and/or fascia has been less well described. We report the usefulness of the composite ALT flap in six complex hand trauma cases, four male and two female (age range 14-46 years). The palm of the hand was affected by injury in three cases, the dorsum in two cases, and the radial side in one case. The first web formed part of the injury in three cases. There was variable involvement of the tendons, nerves and bones. Fascia lata was included in the flap to provide a gliding surface in four cases, part of the vastus lateralis muscle was included to obliterate dead space in two cases and to create a first web in one case, and a bone block from the iliac crest was included to reconstruct the lost metacarpals in one case. All flaps survived with minimal complications. This work shows that the anterolateral thigh composite flap is a reliable option when multiple tissue types are required in hand reconstruction.
