椎间盘镜下等离子刀髓核消融的临床研究

目的：探讨、总结椎间盘镜下等离子刀髓核消融治疗腰椎间盘突出症的临床效果。方法：将150例腰椎间盘突出症患者随机分为两组分别进行微创椎间盘镜下髓核摘除术（MED）。A组：常规MED手术;B组：常规MED手术后,同时应用等离子刀对椎管内残余组织进行消融、皱缩,成形。随访最长12～24个月,平均18个月。分别于术后3、12个月进行疗效评定比较,并行CT复查。结果：B组临床疗效较A组有显著性差异（A组与B组术后3、12个月统计学χ2值分别为4.13、4.81;P〈0.05）,优于A组,CT影像学复查示B组优于A组。结论：椎间盘镜下等离子刀髓核消融治疗腰椎间盘突出症,较单纯的MED手术临床疗效好,是治疗腰椎间盘突出症的较佳选择。

The clinical study of radiofrequency coblation nucleoplasty on Microendoscopic discectomy

Objective：To evaluate,summary the effection of radiofrequency coblation nucleoplasty for lumbar intervertebral disc prolapse on microendoscopic discectomy（MED）.Methods：150 patients were separated for two groups at random.Both groups were disposed with microendoscopic discectomy.Group A：general MED surgery;group B：after general MED surgery,treating the remnant with radiofrequency coblation nucleoplasty.Gather materials in 12～24 months,average of 18 months.Comparison of efficacy evaluation,CT countercheck in 3 months and 12 months.Results：The efficacy evaluation of group B was better than group A at 3 months,12 months（group A and B：χ2=4.13、χ2=4.81.P0.05）.Conclusion：The effection of radiofrequency coblation nucleoplasty for lumbar intervertebral disc prolapse on microendoscopic discectomy is better than simple MED,it is a better suegery method for lumbar intervertebral disc prolapse.
