RESUMEN
Objective To summarize the clinical efficacy of free KISS lateral femoral circumflex artery perforator flap in repairing defects of limbs.Methods Twelve cases were suffered wound surface defects on hands and feet.And the defects were repaired by flap construction from October,2010 to May,2013,based on the characteristics of the defects combined with anatomical features of the free lateral femoral circumflex artery perforator flap.Length of flap was adopted as the width for direct suture in the flap donor.Results Postoperative flap and donor area preliminarily healed.There was no vascular crisis.Twelve cases received 6-18 months followed-up (averaged of 12 months).The skin flap was good in color and texture.The dorsal flap was a bit bloated.Linear scar was remained in distal flap donor area.The quadriceps muscle power level 5,knee flexion,extension 10°-180°.Quadriceps strength,knee flexion and stretch activities were all normal.The flaps recovered protective sense.Four cases had tendon adhesion after hand tendon transplantation.The finger function was well recovered after release.At the last followup,the functions of the upper limbs were evaluated according to the trial evaluation standard of the Hand Surgery Association of Chinese Medical Association:6 cases were excellent,1 case was good,and 1 case was qualified.Conclusion The design of the lobulated tissue flap of the lateral femoral circumflex artery descending branch is flexible.Large area of the surface defect can be repaired.The flap donor area is directly sutured.It is an ideal method to repair the wound tissue defect.
