A Retrospective Research on 56 Hips of Avascular Necrosis of Femoral Head in Pericollapse Stage treated by Bone Grafts and Internal Fixation Support Combined with Traditional Chinese Medicine

Objective:To study the effect of surgical treatment with core depression plus trabecular bone and autogenous fibular grafting on osteonecrosis of the femoral head.Methods:From January 2004 to March 2005,45 patients with necrosis of the femoral head(56 hips) were treated with core depression,trabecular bone and antogenous fibular grafting,which were fixed by hollow compression screw.Meanwhile,they were also given Tongluo Shenggu Capsule orally.according to ARCO classification system,6 hips fell into stage ⅡA,15 hips in stage ⅡB,9 hips in stageⅡC,3 hips in stage ⅢA,15 hips in stage ⅢB,and 8 hips in stage ⅢC.Results:All patients were followed up for 12 to 27 months(17.5months on average).The total good and effective rate was 85.7% according Harris hip score.In stage Ⅱ,the good and effective rate was 90.0% including 27 hips,and it was 80.7% in stage Ⅲ including 21 hips.Imaging evaluation presented 66% good and effective rate(37 covered).Conclusion:Core decompression combined with bone grafting and hollow compression screw fixation can effectively cure osteonecrosis of the femoral head.
