Objective To study use of the large reverse sural neurocutaneous flap （LR.SNF） for the coverage of the extensive defect in the lower extremity. Methods LP,.SNF transfer was performed in 20 lower extremities in 20 patients for repair of the extensive defect in the lower leg, ankle, and foot. In this series, the flap size ranged from 8cm×16cm to 12cm×24cm. Results Flap survival was achieved in all extremities. Distal partial flap necrosis was occurred in 2 extremities, which required additional wound care to achieve healing. The follow-up ranged from 3 months to 4 years. At the final follow-up, the appearance of the flap was acceptable in all cases. Conclusion The LRSNF is reliable for repair of the extensive defect in the lower extremity.
