Objective:To evaluate the therapeutic effect of the drilling decompression combined with Chinese herbs treatment on the early osteonecrosisof femoral head(ONFH).Methods:30 cases with early ONFH were divided randomly into a treatment group of 30 cases and a concontrast group of 30 cases.All the cases were given regular drilling decompression,in addition,the treatment group received Chinese herbs treatment after the surgery.The two groups were compared by Harris scores,image diagnosis and comprehensive therapeutic effect.Results:The Harris scores of the treatment group one month,three months and one year after surgery are all better than those of the contrast group(P＜001).The two groups have no significant difference after the first three months Chinese herbs treatment for image diagn osis,but after one year of treatment of Chinese herbs the treatment group showed better results for both image diagnosis(P＜005)and comprehensive therapeutic effect(P＜005).Conclusion:The drilling decompression combined with Chinese herbs treatment could be used to treat early ONFH with better therapeutic effect than pure drilling decompression,and no significant side effects.
