Complex Hand Reconstruction using a Novel Two-stage Temporary Ectopic Implantation of the Contralateral Upper Limb

Ectopic transplantation of the hand remains a rare, innovative yet valuable operation in select cases of trauma and amputation. We aim to describe a novel technique of complex hand reconstruction using a two-stage ectopic implantation of the contralateral upper limb. A male patient with a near complete avulsion amputation of the right upper limb at the level of the mid-forearm and a crushing injury to his left hand was admitted after a farming accident. The right palm was ectopically transplanted to the left lower limb and both upper limbs underwent debridement with vacuum assisted dressings (VACs). There was eventual dieback of the left thumb, ring and little finger with a large palmar soft tissue defect that was eventually reconstructed using segments of the ectopically transplanted limb in two separate operations. The patient made an uneventful postoperative recovery and managed to regain protective sensation and gross motor function of his reconstructed hand.
