Objective：To observe and evaluate perforator flap’s role in wound healing in thelower extremity, explore its application in the leg wound repairs.Methods：1is to identify and mark posterior tibial artery preferably by usinghand held Doppler probe2surgically remove any of the infected tissue along withnecrotic tissue3design a perforator flap size range of3cm×5cm～8cm×16cm inlower extremity which will be transplanted to repair skin tissue defects.4ready andraised flap now can be rotated around its perforator as required by the target site torepair5raise the cover flap thickness skin graft secondary wounds.Results：The perforator flap was applied in the repair and reconstruction of thelower extremity on21cases among which16were Male and5female and betweenthe ages of17to68. All of the healing effects were good. After the follow-up from6to12months, the appearance and function of the injured lower extremity wassatisfactory.Conclusion：Perforator flap of lower extremity have stable blood supply. It doesnot damage any major vascular. It can repair the skin soft tissue defect of the lowerextremity traumas. It is ideal for reconstruction of lower extremity defects.
