Abstract：Objective To study the comparison of extracorposreal shock waves with core decompression for early-stage trauma-induced femoral head necrosis .Methods Totally 132 cases of patients admitted in our hospital from Jan.2006 to Jan.2009 were randomly divided into extracorposreal shock waves group (69 cases,79 hips) and core decompression group (63 cases,82 hips).The clinical effect between the two groups was observed and com-pared.VAS score was recorded before treatment ,3 months after treatment and at the last follow up .Harris scoring system was used to evaluate hip functions .The survival time of femoral head was recorded .Results The mean du-ration of follow up was 96 months,ranging from 80 to 113 months.There was no significant difference in age ,dura-tion of follow up,VAS and Harris scores between the two groups before treatment (P>0.05).The VAS scores in ex-tracorposreal shock waves group 3 months after treatment and at the last follow up were significantly lower than those in the core decompression group(P<0.05).The Harris scores in extracorposreal shock waves group 3 months after treatment and at the last follow up were significantly higher than those in the core decompression group (P<0.05). The total excellent and good rate in extracorposreal shock waves group was 82.28%,which was significantly higher than that in the core decompression group (60.98%,P<0.05).The average survival time of femoral head in extra-corposreal shock waves group was significantly longer than that in the core decompression group ( P <0.05 ) . Conclusion Long-term curative effect was good in both extracorposreal shock waves group and core decompression group.Extracorposreal shock waves improved the hip function better than core decompression .Clinical effect of ex-tracorposreal shock waves treatment was better than core decompression in the treatment of early -stage trauma-in-duced femoral head necrosis .
