MRI成像参数与腰椎间盘突出症患者腰椎功能相关性及对经皮椎间孔镜术后的疗效

Correlation between MRI imaging parameters and lumbar function in patients with lumber disc herniation and the therapeutic value of percutaneous foraminoscopy

目的分析MRI腰部成像参数与腰椎间盘突出症患者腰椎功能相关性及对经皮椎间孔镜术后疗效评估价值。方法选取2021年1~12月我院收治的92例腰间盘突出患者为观察组,选择同期健康体检者76例为对照组。观察组患者均进行经皮椎间孔镜术治疗,对所有患者进行MRI检查,比较两组研究对象腰部成像参数,通过Pearson相关分析MRI腰部成像参数与腰椎间盘突出症患者腰椎功能的相关性,采用ROC曲线预测MRI腰部成像参数评估经皮椎间孔镜术后疗效的价值。结果观察组患者腰大肌横截面面积、多裂肌横截面面积、椎间孔中部矢状径、椎间孔面积小于对照组,差异有统计学意义(P<0.05);Pearson腰大肌横截面面积、多裂肌横截面面积、椎间孔中部矢状径、椎间孔面积与腰椎功能呈正相关关系(P<0.05);ROC曲线结果显示,MRI腰部成像参数评估经皮椎间孔镜术后疗效具有较高的敏感度和特异性。结论MRI腰部成像参数与腰椎间盘突出症患者腰椎功能存在一定的相关性,其可以作为评价经皮椎间孔镜术疗效的重要依据。

Objective To analyze the correlation between MRI lumbar imaging parameters and lumbar function in patients with lumber disc herniation and evaluate the efficacy of percutaneous foraminoscopy.Methods A total of 92 patients with lumbar disc herniation admitted to our hospital from January 2021 to December 2021 were selected as the observation group,and 76 healthy subjects in the same period were selected as the control group.Percutaneous foraminoscopy was performed on all patients in the observation group,and MRI was performed on all patients.Waist imaging parameters of the two groups were compared.Pearson was used to analyze the correlation between MRI lumbar imaging parameters and lumbar function of lumber disc herniation patients.ROC curve was used to predict the value of MRI lumbar imaging parameters in evaluating the efficacy of percutaneous foraminoscopy.Results The cross sectional area of psoas major muscle,multimultius muscle,sagittal diameter of the middle foramen and the area of the foramen in the observation group were significantly smaller than those in the control group with statistical significance(P<0.05).Pearson correlation analysis showed that the cross section area of psoas major,the cross section area of multifidus,the sagittal diameter of the middle foramina and the area of the foramina were positively correlated with lumbar function(P<0.05).ROC curve results showed that MRI lumbar imaging parameters had high sensitivity and specificity in evaluating the postoperative efficacy of percutaneous foraminoscopy.Conclusion MRI lumbar imaging parameters are correlated with lumbar function of lumber disc herniation patients,which can be used as an important basis for evaluating the efficacy of percutaneous foraminoscopy.
