Crossover replantation and fillet flap coverage of the stump after ectopic implantation: a case of bilateral leg amputation.

A successful case of crossover replantation of the left foot to the stump of the right leg and temporary ectopic implantation of the right amputated foot on the forearm is described. The ectopically implanted right foot was used as a free fillet flap for the late reconstruction of the left leg stump. At the latest follow-up examination, 18 months after the accident, the patient was able to walk independently with a prosthesis on the stump of the left leg. Both the cross-replanted foot and the free filleted foot flap, used for the reconstruction of the left leg stump, have maintained adequate protective sensation. The importance of utilization of amputated parts for functional reconstruction is stressed. Crossover replantations and ectopic implantations should be considered in bilateral amputations for the salvage of at least one extremity.
