The aim of this work is to evaluate the efficacy of the reverse sural flap in covering defects in the foot and ankle region when certain technical modifications are employed. We provide a retrospective review of 32 consecutive reverse sural flaps for foot and ankle defects, and compare the technique and results with other reports.

There were 23 fasciocutaneous flaps, 7 fascial flaps, and 2 tissue-expanded flaps. Four flaps (12.5%) suffered significant flap loss, and 4 patients had delayed healing.

Several modifications are suggested to increase the versatility of the sural flap in covering foot and ankle defects, including preserving the mesentery connecting the sural nerve to the deep fascia, inclusion of skin of the upper third of the leg, limiting pedicle width to 2 cm with preservation of a tongue-like skin process all along its length, and generous release of the fascia over the peroneal compartment. In addition, we describe the use of tissue expanded sural flaps.
