C型臂X线机引导脊神经后内侧支阻滞松解术治疗小关节突源性下腰痛的可行性分析

Feasibility analysis of posterior medial branch release of spinal nerve under C-arm X-ray in the treatment of low back pain caused by facet joints

目的研究C型臂X线机透视下引导脊神经后内侧支阻滞松解术治疗小关节突源性下腰痛的可行性。方法100例小关节突源性下腰痛患者,随机分为对照组和研究组,各50例。对照组患者采用彩超下定位治疗,研究组患者使用C型臂X线机透视下引导脊神经后内侧支阻滞松解术治疗。比较两组治疗前后疼痛评分、腰椎功能评分及不良反应发生情况。结果治疗后,研究组疼痛评分为(3.25±0.15)分,低于对照组的(4.93±0.21)分,差异有统计学意义(P<0.05)。治疗后,研究组腰椎功能评分为(21.01±2.13)分,高于对照组的(17.02±1.12)分,差异有统计学意义(P<0.05)。研究组不良反应发生率为8.00%,低于对照组的32.00%,差异有统计学意义(P<0.05)。结论C型臂X线透视下引导脊神经后内侧支阻滞松解术效治疗小关节突源性下腰痛可行。

Objective To study the feasibility of posterior medial branch release of spinal nerve under C-arm X-ray in the treatment of low back pain caused by facet joints.Methods A total of 100 patients with low back pain caused by facet joint were randomly divided into control group and research group,with 50 cases in each group.Patients in the control group were treated with color Doppler ultrasound,and patients in the research group were treated with posterior medial branch release of spinal nerve under C-arm X-ray.The pain scores and lumbar function scores before and after treatment,and occurrence of adverse reactions were compared between the two groups.Results After treatment,the pain score of the research group was(3.25±0.15)points,which was lower than(4.93±0.21)points of the control group,and the difference was statistically significant(P<0.05).After treatment,the lumbar function score of the research group was(21.01±2.13)points,which was higher than(17.02±1.12)points of the control group,and the difference was statistically significant(P<0.05).The incidence of adverse reactions in the research group was 8.00%,which was lower than 32.00%in the control group,and the difference was statistically significant(P<0.05).Conclusion Posterior medial branch release of spinal nerve under C-arm X-ray is feasible in the treatment of low back pain caused by facet joints.
