Thumb Reconstruction by Pollicization of an Index Finger Stump Combined with a Wrap-Around Flap from the Big Toe

Abstract

A finger stump pollicization combined with a thin wrap-around procedure from the big toe for reconstruction of the thumb is described. This technique permits excellent functional and cosmetic restoration, providing length to the new thumb as well as widening the first web. There is joint motion in the reconstructed thumb. Sensibility of the transferred pulp is good and allows fine pinch without pulp shrinkage. This method is indicated in cases of multidigit amputations, for thumb loss near the carpometacarpal joint.
