【摘要】：目的:分析朝、汉族成人脊髓圆锥末端位置分布特点,为成人蛛网膜下腔阻滞中穿刺间隙的部位选择提供参考依据。方法:回顾性分析本院腰椎核磁共振(MRI)检查资料843例,对每一脊柱单元分为4个节段,椎体直接平分为上中下三个节段,椎间盘为一个节段。在仰卧位脊椎MRI正中矢状位T1W1上见到的最远一点作一垂直于脊髓纵轴的直线,对应于相应的椎体节段或椎间盘即为脊髓圆锥末端的位置,并通过观察旁正中矢状面椎间盘是否完整及冠状位腰椎和肋骨的关系确定椎体序数。观测并记录腰椎MRI检查所示脊髓圆锥末端位置,分析朝、汉族的分布特点。结果:朝鲜族脊髓圆锥末端最高位于T11-12水平,最低位于L3上段水平,主要集中在 L1上1/3(21%)、L1中1/3(15.7%)、L1下1/3(23.5%)和L-2(16.5%),L1椎体至L1-2水平;汉族脊髓圆锥末端最高位于T12上1/3水平,最低位于L2-3水平,主要集中在 L1上1/3(23.7%)、L1中1/3(16.7%)、L1下1/3(18.7%)和 L1-2(14.6%),L1椎体至L1-2水平。男性脊髓圆锥末端位置高于女性(P0.05),汉族男性脊髓圆锥末端位置高于朝鲜族男性(P0.05),汉族女性与朝鲜族女性之间未见差异(P0.05),脊髓圆锥末端位置随年龄增长而下移(P0.05)。结论:成人脊髓圆锥末端位于L2-3水平以下,L2-3作为腰麻穿刺间隙有脊髓损伤的风险,其位置与民族、性别和年龄有相关性,选择椎管内麻醉穿刺间隙时应考虑上述相关因素。
[Abstract]:Objective: to analyze the distribution of the terminal position of spinal cord cones in Korean and Han adults, and to provide a reference for the location selection of puncture space in adult subarachnoid block. Methods: the data of 843 cases of lumbar spine MRI were retrospectively analyzed. Each spinal unit was divided into 4 segments, the vertebral body was divided directly into upper, middle and lower three segments, and the intervertebral disc was divided into one segment. The farthest point seen on the supine MRI median sagittal position T1W1 was a straight line perpendicular to the longitudinal axis of the spinal cord. Corresponding to the position of the corresponding vertebra segment or intervertebral disc at the end of the cone of the spinal cord, The number of vertebrae was determined by observing the relationship between the coronal lumbar vertebrae and the ribs, and the position of the end of the spinal cones was observed and recorded by the MRI examination of the lumbar vertebrae. Results: the ends of the cones of the Korean spinal cord were located at the T11-12 level, and the lowest at the upper L3 level, mainly at 1 / 3 / 3 ~ (21) L ~ (-1) and L ~ (2) / L ~ (1 / 3) and L ~ (2) ~ (1 / 3) ~ (3 / 3) T _ (2) T _ (1) T _ (1) and L _ (2) T _ (1) T _ (1) and L _ (2). The ends of the spinal cones in Han nationality were highest at the level of 1/3 on T12 and lowest at the level of L2-3. Mainly concentrated on 1 / 3 / 3 / 23. 7 / L1 of L1, 1 / 3 / 3 / 16. 7 and 1 / 3 / 3 / 18. 7 / L) and L _ (1-2) ~ 14.6T / L ~ (-1 ~ 2). The end position of male spinal cone was higher than that of female (P 0.05), that of Han nationality was higher than that of Korean male (P 0.05), and that of Han nationality and Korean women was higher than that of Han nationality and Korean women. There was no difference (P 0.05), but the position of the end of the spinal cones decreased with age. Conclusion: the adult spinal cones are located below the L2-3 level and L2-3 is the risk of spinal cord injury. The location was correlated with nationality, sex and age. The above factors should be considered when selecting the space of puncture of intraspinal anesthesia.
