[Contralateral finger transplantation for reconstruction of thumb function].

Finger transplantation from the contralateral hand for the purpose of thumb reconstruction is rarely performed, more widespread use of this procedure being prevented by the psychological problems for the patients. Two cases are described, in which a previously damaged index finger of the contralateral hand was transplanted. The metacarpophalangeal joint of the index finger replaced that of the thumb in both cases. A strong pinch grip with sensibility was achieved. The aesthetic result was substantially improved, both on the donor and the recipient hand.
