LI Gang,WANG Jun-yu(The Hospital Affiliated to Shandong University of Chinese Medicine,Jinan,250014,China)  
Objective: To observe the curative effect of Chinese drug combined with core decompression on caput femoris necrosis,and provide the clinical evidence for protecting coxa.Method: 42 cases with caput femoris necrosis in ARCO in stage I and stage II were divided into two groups randomly.20 cases(26 coxas) in control group were treated with Chinese drug only,and the other 22 ones(28 coxas) in treatment group were done with Chinese drug and core decompression.One course of treatment included 3 months.After two courses of treatment the curative effect was evaluated.Result: In treatment group 7 coxas was recovered,16 ones excellent,5 ones effective and no one ineffective.The total effective rate was 100%(95%CI=87.7%-100.0%).In control group 1 coxa was recovered,11 ones excellent,12 ones effective and 2 ones ineffective.The total effective rate was 92.3%(95%CI=74.9%-99.1%).There was significant difference between the two groups on the effective rate(u=2.760 1,P=0.007 7).Conclusion: Chinese drug combined with core decompression can relieve or eliminate the pain in coax among caput femoris necrosis better than only Chinese drug,improve coax activity and the physiologic function of lower extremity,and promote bony frame to repair.
