Abstract

Traumatic calcanectomy is a complicated rare condition that results in chronic pain and loss of limb function as the calcaneus is crucial for bearing weight. For an adult, possible treatment options are limited to below knee amputation, bone grafts, and 3D prosthesis; however, for the pediatric population, therapeutic data are scarce. In this case report, the authors describe a technique that provides the possibility for hindfoot reconstruction while maintaining growth potential without traumatizing other anatomic regions. A 5-year-old patient presented in the emergency department after he accidentally slipped under a lawnmower, which resulted in full calcaneal amputation with large bone and plantar soft tissue defects from the medial to lateral malleoli. Four days later, reconstructive surgery was performed using a composite vascularized pedicle growth plate flap. The flap was based on the retrograde anterior tibial artery and consisted of the peroneus longus muscle and fasciocutaneous perforator flap to maintain soft tissue coverage. The calcaneus was reconstructed by a double barrel fibular transplant localizing the growth plate in the distal part of the neocalcaneus. Full consolidation of the fibular barrels was achieved and the growth plate was still open at the 8-year follow-up. The fibular transplant has acquired a similar shape to a calcaneus with symmetric flattening and opposite side angulation. The patient's lower extremity functional score was 78/80 points. Reconstruction of an amputated calcaneal bone is rare and complicated, especially for pediatric patients. Authors demonstrate treatment with a complex vascularized flap for sustained growth and good functional outcome in the long term.
