Reconstruction of plantar heel defect using reinnervated, skin-grafted flexor digitorum brevis flap

Abstract

Two cases with extensive plantar avulsion injuries had their heel defects resurfaced initially with full thickness skin grafts. Two months later, reinnervation presented in areas of grafted skin innervated by medial and lateral plantar nerves. No reinnervation was found in the plantar heel region originally innervated by the medial calcaneal nerve. Heel ulceration in the non-sensate, grafted skin occurred in the first case. Reinnervated, skin-grafted flexor digitorum brevis muscle flaps were then used for reconstructing the non-sensate plantar heels. There was no breakdown of skin during the follow-up period of 8 months and 6 months respectively. This method provides sensate and durable cover for extensive plantar heel defects. © 1991 The Trustees of British Association of Plastic Surgeons. All rights reserved.
