Peroneal Artery–based Propeller Flap to Cover the Medial Distal Tibia in the Absence of the Posterior Tibial Artery

A healthy 28-year-old woman restrained driver presented to the trauma unit post-MVC with significant vehicular intrusion. Examination demonstrated a 15-cm transverse wound over the medial malleolus and anterior ankle with exposed muscle, tendon, and bone without gross contamination. Her physical examination was otherwise unremarkable. Distal to the wound, there was no Doppler signal in either dorsalis pedis or posterior tibial arteries and the foot appeared cold with delayed cap refill. She was taken to the operating room urgently for debridement and irrigation, open reduction internal fixation of both distal tibia and fibular fractures, and supplemental external fixation application. The foot regained a normal color and capillary refill upon reduction, and biphasic Doppler signals returned.
