超声引导下低温等离子射频消融术治疗腰椎关节源性腰痛的疗效分析

Efficacy of ultrasound-guided low-temperature plasma radiofrequency ablation in treatment of lumbar arthrogenic low back pain

目的分析超声引导下低温等离子射频消融术治疗腰椎关节源性腰痛的临床疗效。方法选择2019年8月至2020年8月腰椎关节源性腰痛患者60例,随机分为对照组和观察组各30例,对照组采用超声引导下腰脊神经后支神经阻滞治疗,观察组采用超声引导下腰椎脊神经后支低温等离子射频消融术治疗。记录治疗前与治疗后1 d、7 d、1个月、3个月时患者视觉模拟评分法(VAS)评分以及功能障碍指数(ODI)评分;比较两组患者治疗后6个月疗效。结果两组患者术后1 d的VAS评分、ODI评分均较术前有明显下降(P<0.05)。术后7 d、1个月、3个月观察组的VAS评分、ODI评分均显著低于对照组,差异有统计学意义(P<0.05)。6个月后观察组优良率为83.33%,明显高于对照组的30.00%,差异有统计学意义(P<0.05)。结论超声引导下腰脊神经后支低温等离子射频消融术治疗腰椎关节源性腰痛有较好疗效,在临床上有推广应用价值。

Objective To analyse the clinical efficacy of ultrasound-guided low-temperature plasma radiofrequency ablation in treatment of lumbar arthrogenic low back pain.Methods Sixty patients with lumbar arthrogenic low back pain were selected from August 2019 to August 2020 and were randomly divided into control group(30 cases)and observation group(30 cases).The control group was treated with ultrasound-guided nerve block of posterior ramus of lumbar spinal nerves for lumbar arthrogenic low back pain.The observation group received ultrasound-guided low-temperature plasma radiofrequency ablation in posterior ramus of lumbar spinal nerves for treatment of lumbar arthrogenic low back pain.The Visual Analogue Scale(VAS)scores and Oswestry Disability Index(ODI)scores of the patients were recorded before treatment and 1 day,7 days,one month and three months after treatment.The clinical efficacy was compared between the two groups 6 months after treatment.Results Compared with those before treatment,the VAS scores and ODI scores in the two groups were decreased significantly 1 day after treatment(P<0.05).However,the VAS scores and ODI scores in the observation group were significantly lower than those in the control group 7 days,one month and three months after operation,and the differences were significant(P<0.05).After 6 months,the excellent and good rate of the observation group(83.33%)was significantly higher than that of the control group(30.00%),and the difference was significant(P<0.05).Conclusion Ultrasound-guided low-temperature plasma radiofrequency ablation in posterior ramus of lumbar spinal nerves is effective for treatment of lumbar arthrogenic low back pain,and it is worthy of clinical application.
