Peroneal artery perforator‐based flaps for reconstruction of middle and lower third post‐traumatic defects of the leg

Abstract

Grade IIIb open tibial fractures require local or free flaps for cover of the fracture site. Perforator flap surgery is an innovative method for wound cover in this setting. The anatomy of perforating vessels of the peroneal artery is well described. All patients who underwent peroneal artery perforator-based flap cover for acute Grade IIIb fracture tibia between December 2011 and March 2013 were prospectively studied. The wounds were located either in middle or in lower third of the tibia. Flaps were performed under loupe magnification after identifying perforators preoperatively with handheld Doppler. All flaps were of a hockey stick or J design, incorporating the peroneal skin territory and completely islanded. Patients were followed up until all wounds were epithelialized. Eleven patients were identified. Eleven flaps were performed, out of which 10 survived entirely and served the purpose of stable wound cover. One patient sustained partial flap necrosis, which was debrided, and another local flap was performed. More than one perforator could be identified and retained in six of these 11 patients. The peroneal artery perforator-based flap is reliable and reproducible in an acute post-traumatic setting. It should be considered as a suitable alternative for reconstruction for limited defects with exposed fractured tibia over the middle and lower third of the leg.
