Forefoot amputation and free flap reconstruction for fracture-dislocations of the Lisfranc joint associated with plantar soft tissue defects: A report of two cases

A 55-year-old man sustained an open fracture-dislocation of the Lisfranc joint. Soft tissue defects occurred in the dorsal and plantar parts distal to the midfoot. After transmetatarsal amputation, the Lisfranc joint was reduced and fixed using a screw and staples, and the dorsal and plantar soft tissue defects were covered with a free latissimus dorsi myocutaneous flap. Two years postoperatively, the patient was able to walk without an orthosis and wear regular shoes, and no equinovarus deformity was observed. Plain radiographs showed a reduced Lisfranc jointFor fracture-dislocations of the Lisfranc joint associated with plantar soft tissue defects, anatomical reduction and fixation of the Lisfranc joint, free flap reconstruction of the plantar weight-bearing area, and forefoot amputation help prevent equinovarus foot deformities and preserve gait function.
