目的:比较研究单节段L4/L5椎间盘突出引起单纯单侧感觉或运动异常时突出髓核在MRI上的分布差异。方法回顾分析22例单节段L4/L5椎间盘突出并单侧单纯感觉或运动异常的患者的MRI影像资料,分为运动异常组(A组)和感觉异常组(B组),分别将2组突出髓核的的外侧缘、内侧缘、突出最顶点在横向位上赋值,将突出最顶点在矢状位上赋值,比较2组间赋值的差异。结果 B组突出髓核的外侧缘及突出最顶点,突出髓核的最内侧缘较A组更偏向有症状侧,2组之间有明显差异,B组突出最顶点的矢状位赋值较A组的大。结论感觉异常患者较运动异常患者的突出髓核更偏向受压迫的神经根,且突出髓核在矢状位上更大。
目的:比較研究單節段L4/L5椎間盤突齣引起單純單側感覺或運動異常時突齣髓覈在MRI上的分佈差異。方法迴顧分析22例單節段L4/L5椎間盤突齣併單側單純感覺或運動異常的患者的MRI影像資料,分為運動異常組(A組)和感覺異常組(B組),分彆將2組突齣髓覈的的外側緣、內側緣、突齣最頂點在橫嚮位上賦值,將突齣最頂點在矢狀位上賦值,比較2組間賦值的差異。結果 B組突齣髓覈的外側緣及突齣最頂點,突齣髓覈的最內側緣較A組更偏嚮有癥狀側,2組之間有明顯差異,B組突齣最頂點的矢狀位賦值較A組的大。結論感覺異常患者較運動異常患者的突齣髓覈更偏嚮受壓迫的神經根,且突齣髓覈在矢狀位上更大。

Objective To compare the nucleus pulposus distribution on MRI in patients with unilateral sensory or motor abnormal caused by lumbar disc herniation of L 4/L5 .Methods A total of 22 patients of L 4/L5 disc herniation with unilateral sensory or motor abnormal were found , and their MRI were collected .The patients were divided into 2 groups:unilateral motor abnormal group(Group A) and unilateral sensory abnormal group (Group B).The outer lateral edge, the inner lateral edge and the vertex of the nucleus pulposus were assigned in the horizontal position .The vertex of the nucleus pulposus was also assigned in the sagittal position .Then Assignment scores of the 2 groups were compared .Results Compared with Group A , Group B showed that the outer lateral edge , the inner lateral edge and the vertex of the nucleus pulposus were more close to the side with symptoms in the transverse section .The sagittal scores of the vertex of the nucleus pulposus in Group B were lager than that in the Group A .Conclusion The nucleus pulposus of unilateral sensory abnormal patients are close to the com -pressed nerve root , and its distribution is larger in the sagittal position , compared with motor abnormal patients .
