Retrograde flow medial plantar artery flap reconstruction for defects of the dorsal metatarsophalangeal region

Abstract

INTRODUCTION: Complex reconstructions of the foot region are planned based on the anatomical subunits affected by the etiological factors of lesions. We have several options for covering defects of the back of the feet, from the simpler ones, such as local graft and local flap at random and locoregional pedicled flaps, to the more complex ones, such as free flaps. Here, we report a case in which an unpublished technique using a retrograde flow medial plantar flap in the reconstruction of dorso-distal structures of the foot was used. Its originality consisted in the passage of the flap of the plant to the back through the first intermetatarsal space. METHODS: The patient was a 20-year-old woman who had a motorcycle accident, wherein she sustained foot trauma with loss of back substance at the first to fifth metatarsal level, with bone and tendon exposure, and retrograde flow medial plantar flap was used, with transposition to the back of the foot. RESULTS: The reconstruction of the distal region of the forefoot and fingers is a challenge. Grafts are not ideal for deep defects and exposure of noble structures. Local flaps are inaccessible for finger defects. Furthermore, the free flaps are well indicated for large defects. The flaps of the medial plantar artery are indicated and consecrated to the forefoot region, and some authors have modified to the dorsum region of the first metatarsal. CONCLUSION: This flap is useful for reconstruction of feet with dorsal lesions through this new technique that is unpublished in the literature, with the originality of the passage of the pedicle from the plant to the back through the first intermetatarsal space.
