Hand reconstruction using the thin anterolateral thigh flap

Abstract

Background: Perforator flaps have been introduced for various kinds of reconstruction and resurfacing; in particular, the free thin anterolateral thigh flap is becoming one of the most preferred options for reconstruction of soft-tissue defects.

Methods: Between 1999 and 2002, the authors used this flap as a free flap for nine cases for covering hand defects after burn, crushing injuries, or severe scar contracture release. There were eight men and one woman, the mean age of the patients was 31 years, and the size of the flaps ranged from 7 x 3.5 cm to 15 x 9 cm; thinning was performed in all flaps.

Results: All flaps survived completely, and the donor site was closed directly in seven cases; in two cases, the exposed muscle was covered with split-thickness skin graft.

Conclusions: The anterolateral thigh flap was thin enough for defects on the dorsum and/or palm of the hand and for first web reconstruction after scar contracture release. It has many advantages in free flap surgery including a long pedicle with a suitable vessel diameter, and the donor-site morbidity is acceptable. The thin anterolateral thigh flap is a versatile soft-tissue flap that achieves good hand contour with low donor-site morbidity.
