神经根沉降征对于腰椎管狭窄患者术后的预测价值

Predictive Value on Postoperative Effect for Nerve Root Sedimentation Sign in Patients with Lumbar Spinal Stenosis

研究分析神经根沉降征对于腰椎管狭窄患者预后的预测价值。回顾性研究自2013年9月-2015年6月于笔者所在医院脊柱外科接受治疗的腰椎管狭窄患者,检测神经根沉降征阳性及阴性患者术前及术后ODI评分、VAS评分,术后Macnab疗效评定,比较两组间数据,分析两组患者的术后疗效是否有差异。结果显示两组患者术后症状均明显改善,两组间术前及术后VAS评分差异无统计学意义（P〉0.05）,两组间术后ODI评分及Macnab疗效评定统计结果差异有统计学意义（P〈0.05）。因此,阳性神经根沉降征的腰椎管狭窄患者较阴性组预后预测价值更令人满意。

To analyze the predictive value of postoperative effect for nerve root sedimentation sign in patients with lumbar spinal stenosis,a retrospective study from September 2013 to June 2015 at Department of Spinal of the First Affiliated Hospital of Liaoning Medical University.The authors detected the Oswestry disability index and pain visual analog scale before and after spine surgery and detected the Macnab efficacy evaluation after spine surgery,compared the data between two groups,analyzed that there was a difference between the postoperative effect of lumbar spine stenosis with positive and negative nerve root sedimentation.The results showed that the symptoms of both groups were improved significantly after spine surgery,and the difference of VAS between two groups before and after spine surgery had no statistical significance（P〉0.05）.The difference of ODI and Macnab efficacy evaluation between two groups after spine surgery had statistical significance（P〈0.05）.Therefore,we conclude the postoperative effect of positive group were more satisfied than negative group.
