II期股骨头坏死两种减压方法的疗效对比

目的：对比分析髓芯减压与钻孔减压在II期股骨头坏死治疗方面的疗效差异。方法：将2008～2012年于南阳市第一人民医院骨科就诊，确诊为II期股骨头坏死的患者，随机分为两组，分别行髓芯减压、钻孔减压治疗，填写CRF表，收集各阶段影像材料，通过分析随访数据对比两种方案疗效差异。结果：所有42例病人均完成了随访，治疗后Harris评分为（85.22±16.04）分，得分平均增加（20.03＋7.85）分，其中，临床痊愈11例，有效22例，无效6例。结论：①应用髓芯减压治疗股骨头坏死疗效明显优于钻孔减压。②对于II期股骨头坏死，保髋治疗具有良好的疗效。

The comparison of curative efficacy of two pressure-reducing methods for femoral head necrosis of second stage

Objective：To co mpare and an alyze th e dif ference between core d ecompression an d drilling d ecompression in tre ating femoral h ead n ecrosis of second stag e.Methods：Patients diagno sed with f emoral h ead ne crosis of second stage in th e NO.1 P eople’s Hospital of Nanyang City from 2008 to 2012 were divided into two groups randomly. One group was given core decompression, the other drilling decompression. The CRF forms were filled and image materials of various stages was collected.The difference of the two treatment programs was analyzed according to the follow-up data. Result：all the follow-up observations of the 42 patients was completed. After the treatment, the Harris score was （85.22±16.04） and the average increase of the score was （20.03＋7.85. 11） patients recovered, 22 had effects, and 6 patients had no effect. Conclusion： ①In the treatment of femoral head necrosis, core decompression is m ore effective than drilling decompression. ②For femoral head necrosis of second stage, hip-salvage treatment works well.
