目的 利用CT数据观察腰神经根及其与主要毗邻结构的位置关系,并对其进行三维构建与测量,为经皮穿刺腰椎间盘术提供解剖学数据.方法 选取30例健康成人腰骶部的CT连续断层扫描数据集导入Mimics 17.0软件,分割出相关结构,获得各结构的图层,对各结构进行三维重建和虚拟显示,并对腰神经根及周围主要结构进行观察及相关测量.结果 L3~L4椎间盘层面到L5~S1椎间盘层面腰神经根与上关节突的最近距离逐渐增大;三维模型清楚地显示了腰神经根及其主要毗邻结构在腰骶部的形态和空间位置关系;腰椎间盘的厚度越往下越厚,而腰椎间盘后缘中点到上位腰椎棘突末端的距离,先增大再减少,在L3~L4椎间盘到上位腰椎棘突末...

Objective To observe the positional relationship of lumbar nerve roots and its main adjacent structures with CT data, and to conduct 3 D construction and measurement, so as to provide anatomical basis for percutaneous lumbar diskectomy （PLD）. Methods CT serial tomography dataset of 30 healthy adults＇ lumbosacral portions were imported into Mimics 17.0 software to segment related structures and ob- tain the layers of different structures. The structures were 3D reconstructed and virtually demonstrated. The lumbar nerve roots and their main su...
