[Reconstruction surgery after traumatic amputation of the thumb].

Reconstruction of the thumb after traumatic mutilation constitutes a delicate indication in order to select the technique most adapted to the patient's functional needs and esthetic desires. Pollicizations of healthy fingers are now used less frequently, except in the clinical context of very proximal amputations, but amputations of mutilated fingers remain a frequent indication. Progressive lengthening was associated with a high complication rate, although these complications have remained minimal. Osteoplastic reconstruction is still occasionally indicated in its modern version of composite flap. Finally, toe transfers now have a large place in young subjects, "tailored" transfer is preferred to first or second toe transfer in the case of isolated amputation of the thumb, due to its esthetic advantages.
