Bone and soft tissue reconstruction with tendon balance in severe foot trauma.

ABSTRACT

In severe foot trauma, it is difficult to determine the level of amputation when the crush injury is severe. We report a case of amputation near Lisfranc that achieved forefoot amputation-like results by using bone and soft tissue reconstruction while considering tendon balance. The patient was a 40-year-old male. The patient's left leg was caught in a garbage truck and sustained a crush injury. The second to fifth metatarsals were amputated at the diaphysis, and a high degree of instability of the Lisfranc joint was observed. A high degree of contamination was detected in the patient's wound, and the second to fifth toes were amputated at the Lisfranc joint during the initial treatment. The ends of the tibialis anterior, tibialis posterior and peroneus longus were preserved. On day 5 in the hospital, Lisfranc joint fixation of the hallux, amputation of the first metatarsal and reconstruction of the peroneus brevis were performed. On day 13, extensor hallucis longus tendon transfer and free anterolateral thigh flap were performed. On day 80, the patient was able to walk in regular shoes or non-orthopedic shoes. One year after reconstructive surgery, the patient had an average SAFE-Q score of 86.2 and mild varus deformity of the foot remained. In cases of severe foot trauma, the aim of reconstruction should be partial forefoot amputation whenever possible.
