摘要
目的分析腰椎间盘突出症患者Lasegue征与MRI影像定位区域的关系。方法纳入自2015-04—2016-07诊治的50例腰椎间盘突出症。对Lasegue征影响因素进行分析,运用MUS分类法和胡有谷区域分类法对患者腰椎间盘突出节段的MRI片进行区域定位,共定位30个区域,分析Lasegue征与定位区域的关系。结果通过突出区域与Lasegue征的Logistic回归分析发现,椎间盘突出区域与Lasegue征有关(OR=1.007),但其敏感性和特异性并不高(AUC=0.5)。秩和检验发现,30个区域的Lasegue征阳性和阴性表现差异无统计学意义(P=1.0)。本组Lasegue征阳性多集中在18个突出区域,突出在Lesions(2A)+Ⅰ、Lesions(2A)+Ⅲ、Lesions(2AB)+Ⅲ和Lesions(3AB)+Ⅰ区域时,Lasegue征表现阳性的趋势更明显。结论 Lasegue征虽然是腰椎间盘突出症的一项特异性检查,突出在不同区域对其影响不显著,敏感性和特异性不高,但突出在某些固定的区域时,Lasegue征却有着呈阳性的趋势。
Objective To analyze the relationship between the Lasegue sign and MRI localization of herniated lumbar discs. Methods Fifty patients who were diagnosed with lumbar disc herniation from April 2015 to July 2016 were retrospectively analyzed. The factors which had influence on the Lasegue were analyzed. The disc herniation sheet segments of the patients were scanned with MRI and targeting them with the classification of the MUS and the HU You-gu, dividing them into 30 MRI localization. The relationship between Lasegue and localization of herniated lumbar discs was analyzed. Results The Logistic regression analysis results of relationship between Lasegue sign and MRI localization of herniated lumbar discs showed the localization of herniated lumbar discs was associated with Lasegue （OR =1.007）, the sensitivity and the specificity of MRI localization of herniated lumbar discs to Lasegue were not high （AUC=0.5）, there was no statistically significant difference in positive and negative Lasegue signs in 30 localization by rank sum test （P =l.0）. Lasegue positive sign was found more concentrated in 18 MRI localization. When herniation of lumbar discs localized mainly at Lesions （2A）＋ Ⅰ, Lesions （2A）＋ Ⅲ, Lesions（2AB）＋Ⅲ and Lesions（3AB）＋Ⅰ, the Lasegue would be possible to show positive. Conclusion Although Lasegue sign is a specific examination of lumbar disc herniation, the effect of MRI localization to Lasegue is insignificant, the sensitivity and the specificity are not high. But when herniated lumbar discs are in some localization, the Lasegue would be possible to show positive.
