RESUMEN
In case of soft-tissue defects with bone and tendon exposure on foot, ankle and lower leg, it is often impossible to achieve wound closure by a simple skin graft. The sural artery flap is a fasciocutaneous flap supplied by the sural artery that accompanies the sural nerve and connects with a septocutaneous perforator of the peroneal artery via a suprafascial network of vessels. For the coverage of the defects, we operated 30 cases using modified superficial sural fasciocutaneous island flap based on the proximal or distal. and we covered convoluted wound site with this flap with plicated fascia. We reconstruct complicated skin defects on the foot region(13) and the distal portion of the leg(17). The size of flap varied from 3 x 4 cm2 to 10 x 9 cm2. All 30 flaps survived completely, but minor complications, such as venous congestion, hematoma disappeared after a few days. The main advantage of this flap is a constant and reliable blood supply without sacrifice of a major artery. but disadvantage of this flap is hypoesthesia at the lateral part of the foot. In conclusion, dissection of the superficial sural fasciocutaneous island flap is quite easy and requires less time, and involves less risk to the patient. The nonbulky fasciocutaneous island flap appearance particularly indicated small to medium sized defects with or without convoluted wound surface. The contours of the recipient and donor sites are acceptable aesthetically.
