Multiple toe transfer and sensory free flap use after a traumatic amputation of multiple digits. Surgery done in a single setting: A case study

Abstract

Crush avulsion injuries to the hand with concomitant traumatic amputation of multiple digits can be a devastating injury to the patient. These injuries have multiple issues occurring under emergency conditions. When feasible, replantation of the multiple digits is optimal, but in many cases, it is not possible. Because of the crushing force on the digits, they are not viable candidates for replantation. The usual course of treatment for these patients is a two stage procedure, usually involving a groin flap. Here, we present the case of a patient who had a left hand skin avulsion of the whole palm and P1 of index, long, ring and small fingers. The left index finger had a complete amputation at the P2 level, the long, ring and small fingers all had complete amputations at the P1 level. This injury was dealt with by a left foot second and third toe transplant, a sensory free flap from the left big toe and a fourth toe microvascular free transfer to the left hand. The remainder of the defect was managed with a 10 × 14 cm reversed radial forearm flap and a combination of full and split thickness skin grafts. The procedure was performed in a single operation, obviating the need for a second surgery. This procedure optimized the patient's outcome during a single setting, making it an ideal choice in an emergency setting.
