Limb Preservation and Functional Reconstruction after Complete Amputation and Replantation of the Upper Arm and Thigh

A 26-year-old man was admitted to our hospital due to the replantation of the severed right upper arm and right thigh injury 6 days before. The patient received emergency treatment at a local hospital. He underwent amputation and replantation for the right upper arm and right thigh. After surgery, he experienced fever, limb swelling, and wound pain. At the time of admission to our hospital, the patient exhibited stable vital signs. An infection was found at the replanted wound, and the culture results showed Pseudomonas aeruginosa. After admission, the patient underwent symptomatic antiinflammatory treatment. In addition, he received fracture reduction and external fixation with a bracket, radial nerve exploration and release of the upper and lower limb external fixation with a bracket, upper femur osteotomy, and external fixation with a bracket. He also received reconstruction of elbow flexion functions with biceps femoris tendon transplantation; reconstruction of wrist joint fusion, finger extension function, and palm function; removal of the femoral external fixation with a bracket; and tibiofibular osteotomy and leg lengthening surgery. Moreover, the anterior tibial tendon was fixed to correct foot drop deformity, and the external fixation bracket was removed. Owing to these efforts, the patient achieved limb preservation with well-reconstructed functions.
