Abstract
Two cases of temporary ectopic implantation of a complex amputated foot, followed by replantation to its anatomic position, are reported. Both cases of amputated foot were complicated by devastating soft-tissue injuries in the proximal stump of the amputation, fracture of the femur, and hemorrhagic shock, which ruled out the possibility of primary foot replantation. Both feet were temporarily ectopically implanted onto the contralateral legs, with microvascular anastomoses of the vessels to the recipient posterior tibial artery and saphenous vein. When the patient's general condition allowed, and the soft-tissue defects were repaired, the ectopic implanted feet were replanted to their anatomic positions. Both feet survived the temporary ectopic implantation and second-stage replantation. The length of the injured legs was maintained, and the feet regained their function in 4- and 6-month follow-ups. We conclude that temporary ectopic implantation of amputated parts provides an innovative procedure for the salvage of amputated extremities under special circumstances. A contralateral healthy extremity is an ideal recipient site for temporary ectopic implantation. The temporary ectopic implantation and second-stage replantation of an amputated foot and distal leg with indications can obtain satisfactory results.
