Induced Membrane Wrist Fusion with Ring External Fixator Assistance in a Mangled Upper Extremity: A Case Report

Introduction: In the mangled forearm injury, a decision between limb salvage or amputation must be made. Case Report: This case report highlights a 37-year-old patient that sustained a mangled wrist injury with a substantial amount of bone loss to the distal radius after an All-Terrain Vehicle (ATV) rollover accident. The decision for limb salvage was made and he was treated with the induced membrane technique with wrist arthrodesis using a ring external fixator with a satisfactory outcome. Conclusion: This case report demonstrates the successful use of the induced membrane technique with a ring external fixator as a limb salvage technique to achieve wrist fusion in a mangled extremity with segmental bone loss.
