经皮穿刺臭氧髓核消融术治疗椎间盘源性下腰痛

目的评价采用经皮穿刺臭氧髓核消融术治疗椎间盘源性下腰痛（DLBP）的临床疗效。方法 128例DLBP患者按照治疗方法分为两组：62例患者为经皮穿刺臭氧髓核消融术治疗组,66例患者为保守治疗组。采用MacNab腰腿痛手术评价标准和Oswestry功能障碍指数（ODI）评分比较两组的疗效。结果 128例均获随访,时间12个月。术后第1、2、3、6、9和12个月,根据MacNab腰腿痛手术评价标准,手术治疗组的有效率分别为85.5%、88.7%、91.9%、90.3%、87.1%和83.9%,保守治疗组的有效率分别为68.2%、56.1%、54.5%、54.5%、50.0%和51.5%,各时间点比较差异均有显著性（P〈0.05）。术后第12个月,手术治疗组ODI评分较低,与术前及保守治疗组比较差异有显著性（P〈0.05）。结论经皮穿刺臭氧髓核消融术是一种有效的治疗DLBP的方法,其疗效比较稳定。

Treatment of Discogenic Low Back Pain by Percutanous Ozone Ablation

Objective To assess the clinical efficacy of discogenic low back pain（DLBP） by percutanous ozone ablation.Methods 128 patients with DLBP were divided into two groups according to therapy methods.62 patients were treated with percutanous ozone ablation and 66 patients were treated with conservative treatment.MacNab score criterion and Oswestry disability index（ODI） were used in assessment of the efficacy.Results All the patients were followed up for 12 months.In the 1st,2nd,3rd,6th,9th and 12th month postoperately,according to MacNab score criterion,the effective rates were 85.5%,88.7%,91.9%,90.3%,87.1% and 83.9% in operative treatment group and 68.2%,56.1%,54.5%,54.5%,50.0% and 51.5% in conservative treatment group respectively and there was significant difference between two groups（P〈0.05） .In the 12th month postoperately,ODI was lower in operative treatment group and there was significant difference compared with that preoperatively and in conservative treatment group（P〈0.05） .Conclusion Percutanous ozone ablation is an effective method which can maintain stable clinical efficacy for treatment of DLBP.
