Abstract:
Objective To evaluated the clinical results of treatment of osteonecrosis of the femoral head(ONFH)by using bone flap pedicled with gluteal muscle branch of ascending branch of the lateral femo- ral circumflex artery and transversal branch of the lateral femoral cireumflex artery.Methods Bone flap pedicled with double blood vessels was applied in 32 hips with stageⅡandⅢONFH according to the Fieat staging system.Fifteen hips were in stageⅡand 17 were in stageⅢ.All patients were followed up for a mean of 25 months(range,15-38 months)and were assessed clinically and radiologically according to Harris sco- ring.Selective digital subtraction angiography was performed in 9 cases to confirm the blood reconstruction of femoral head.Results Two cases underwent total hip replacement postoperatively.Preoperative and postop- erative Harris score were 55 and 88.6.Clinical success rate was 90.6% and radiological success rate was 87.5%.DSA demonstrated blood supply was found reconstruction in the necrotic femoral head.Conclusion Transplantation of bone flap pedicled with gluteal muscle branch of ascending branch of the lateral femoral circumflex artery and transversal branch of the lateral femoral circumflex artery appears to be a effective treat- ment for osteonecrosis of the femoral head,blood supply of bone flap and blood reconstruction of femoral head was confirmed.Early clinical results were satisfied.
