Objective To provide a new microsurgical method for the treatment of ischemic necrosis of femoral head (INFH). Methods Basing on the anatomic study,the author designed the greater trochanter bone flap pedicled with middle gluteal muscle branch of lateral femoral circumflex vessel for the treatment of INFH. Results Seventeen patients were performed by the method and the average period of follow up was 2 6 years (range 1 5～3 5 years ).The therapeutic effectiveness is satisfactory. Conclusion The method has little injury and is convenient,which can provide with plenty of blood supply and osteogenic fact for the femoral head.So it is an effective method for the treatment of INFH.
