The purpose through clinical observation , evaluation femoral head drilling decompression bone graft with the living bone injection intra-articular injection treatment INFH clinical efficacy . Methods from March 2007 to September 2009 , orthopedic the 60 cases INFH hospitalized patients were randomly divided into treatment group and control group (n = 30) : patients treated with core decompression of femoral head bone graft living bone injection liquid intra-articular injection , the control group underwent femoral head drilling decompression bone graft ; six months after surgery , patients were observed before and after treatment Harris score imaging efficacy and overall difference in efficacy , statistics , summarize , analyze its effect. Two programs the INFH have a significant effect in the treatment group total effective rate of 90.24% , 74.29% in the control group , both efficacy evaluation and imaging evaluation of significant difference ( P lt ; 0.05 ) . Total efficacy evaluation after the two groups of patients improved significantly , there is a significant difference compared with before treatment ( P lt ; 0.05 ) , significant difference ( P lt ; 0.05 ) between the two groups after treatment , the clinical outcome measures . The Conclusion INFH drilling decompression and bone graft postoperative , the living bone Injection hip articular injection , can effectively relieve the patient 's pain and improve hip function , shorten the pathological process , and promote the restoration of femoral head necrosis , six months follow-up show that the method can significantly improve the patient's symptoms and signs , to prove that the method has obvious superiority .
