背根神经节脉冲射频联合复方倍他米松注射治疗老年退行性腰椎管狭窄症的疗效观察

Effect of dorsal root ganglion pulsed radiofrequency combined with compound betamethasone injection in treatment of senile degenerative lumbar spinal stenosis

目的 探讨背根神经节脉冲射频联合复方倍他米松注射治疗老年退行性腰椎管狭窄症的临床疗效.方法 收集本科室2014年12月至2015年6月收治的经保守治疗无效的老年退行性腰椎管狭窄症患者18例,均行背根神经节脉冲射频联合复方倍他米松注射治疗.记录治疗前及治疗后1 d、3 d、1周、1个月、6个月患者的疼痛视觉模拟评分（VAS）和Oswestry功能障碍指数（ODI）并进行比较.结果 18例患者均顺利完成手术,无术中及术后并发症发生.术前患者VAS评分为（6.5±0.7）分,术后1 d、3 d、1周、1个月、6个月VAS评分分别为（2.7±1.2）分、（2.5±1.4）分、（2.3±1.1）分、（2.4±1.9）分、（2.5±1.3）分.术前患者ODI为（55.0±6.0）%,术后1 d、3 d、1周、1个月、6个月ODI分别为（15.0±6.0）%、（13.0±4.0）%,（12.0±3.0）%,（13.0±6.0）%,（14.0±5.0）%.与术前比较,术后各时点患者VAS评分、ODI均显著降低（均P〈0.05）;而术后各时点患者的VAS评分、ODI比较,差异均无统计学意义（均P〉0.05）.结论 背根神经节脉冲射频联合复方倍他米松注射治疗老年退行性腰椎管狭窄症疗效较好.

Objective To investigate the clinical effect of dorsal root ganglion pulsed radiofrequency combined with compound betamethasone injection in the treatment of senile degenerative lumbar spinal stenosis. Methods Eighteen patients with senile degenerative lumbar spinal stenosis,who underwent ineffective conservative treatment and registered in our department between December 2014 and June 2015,were included in this study. All the patients underwent dorsal root ganglion pulsed radiofrequency combined with compound betamethasone injection. The visual analogue scale （VAS） and Oswestry dysfunction index（ODI）were recorded and compared at baseline and at 1 d,3 d,1 week,1 month,and 6 months after the treatment. Results Eighteen patients underwent the operation successfully,and there were no intraoperative and postoperative complications. The VAS score at baseline and at 1 d,3 d,1 week,1 month,and 6 months after the treatment were 6.5 ± 0.7,2.7 ± 1.2,2.5 ± 1.4,2.3 ± 1.1,2.4 ± 1.9 and 2.5 ± 1.3, respectively. The ODI at baseline and at 1 d,3 d,1 week,1 month,and 6 months after the treatment were （55.0 ± 6.0）%,（15.0 ± 6.0）%,（13.0 ± 4.0）%,（12.0 ± 3.0）%,（13.0 ± 6.0）%,and （14.0 ± 5.0）%, respectively. The VAS scores and ODI were significantly decreased at all the time points after treatment as compared with those at baseline（all P〈0.05）;whereas,there were no statistically significant differences in the VAS scores and ODI at all the time points after treatment（all P〉0.05）. Conclusion The effect of dorsal＆amp;nbsp;root ganglion pulsed radiofrequency combined with compound betamethasone injection is good in the treatment of senile degenerative lumbar spinal stenosis.
