Abstract：Objective：To observe the clinical effect of the therapy of Bushen Tiansui Tang on delayed healing after surgery for femoral fracture and its effect on bone morphogenetic protein-2(BMP-2) ， osteocalcin(BGP) and alkaline phosphatase(ALP) of patients. Methods：A total of 82 patients with delayed healing after femoral fracture surgery were selected as the research object，and were randomly divided into control group(routine treatment) and observation group(routine treatment + Bushen Tiansui Tang)，41 cases in each group. Before and after treatment，the Harris hip scores，each score of 36-Item Short Form Health Survey(SF- 36) and indexes of bone metabolism were compared between the two groups. The clinical efficacy and complication rate of the two groups were compared. Results： After treatment， the total effective rate in the observation group was higher than that in the control group(P＜0.05)，and the incidence of complications in the observation group was lower than that in the control group(P＜0.05). After treatment，the Harris hip scores and each score of SF-36 in the two groups were higher than those before treatment(P＜0.05)，and the above scores in the observation group were higher than those in the control group(P＜0.05). After treatment，the levels of BMP-2，BGP and ALP in the two groups were higher than those before treatment(P＜0.05)，and the levels of BMP-2，BGP and ALP in the observation group were higher than those in the control group(P＜0.05). Conclusion： The therapy of Bushen Tiansui Tang has a definite curative effect on delayed healing after surgery for femoral fracture，which can effectively improve the bone metabolism of patients and enhance the quality of life，with high safety profile.
