射频消融髓核成型术治疗盘源性腰痛疗效观察

目的:通过对盘源性腰痛患者射频消融髓核成型术治疗1年后随访资料的分析,评估该技术的临床治疗效果。方法:2002～2003年,我们对26例通过椎间盘造影复制腰痛试验诊断为盘源性腰痛、经过正规保守治疗3个月无效的患者,采用射频消融髓核成型术治疗,所有患者术后1年随访。通过患者手术后2天内与1年后症状改善率(术前VAS评分术后VAS评分)/术前VAS评分×100%]和主观满意程度进行分析,评价射频消融髓核成型术对盘源性腰痛的治疗效果。结果:所有26例患者术后2天内症状改善率为65%,患者主观满意率达88.5%;术后1年症状改善率为44%,患者主观满意率达30.8%。术后2天内及术后1年随访患者症状改善率和主观满意率与术前相比存在显著差异(P<0.05)。结论:射频消融髓核成型术对盘源性腰痛的治疗术后短期内可以收到较好的治疗效果,但1年后治疗效果会明显降低。

EFFECT OF RADIOFREQUENCY NUCLEOPLASTY ON DISCOGENIC LOW BACK PAIN

Objective:To evaluate the effect of radiofrequency nucleoplasty on discogenic low back pain after 1 year follow-up. Methods: 26 patients were diagnosed as discogenic low back pain by discogram, and received radiofrequancy neucleoplasty treatment. They were followed-up 1 year after operation. The rate of symptom relief (VAS score) and subjective satisfaction were evaluated. Results: For all patients within 2 days postoperation, the rate of symptom relief was 65%, subjective satisfaction 88.5%. After 1 year follow-up, the rate of symptom relief and that of subjective satisfaction was 44% and 30.8%, respectively. There were significant statistical difference(P<0.05) between the rates within 2 days after operation and 1 year follow-up. Conclusion: There were a statistically significant improvement in symptom relief and subjective satisfaction after radiofrequency neucleoplasty. The long-term effect of radiofrequency neucleoplasty was worse than short-term effect.
