摘要
国内外很多学者通过核磁共振观察统计脊髓圆锥末端位置的水平，发现其变化范围为T12-L3椎体，并与年龄、性别、体位、脊髓发育异常等多方面因素有关，而蛛网膜下腔阻滞时常选择L2/L3间隙穿刺，此法会增加脊髓损伤的风险并且有明确病例报道并提供了直接证据。蛛网膜下腔阻滞引起脊髓损伤与定位不准、穿刺针因素、穿刺技术和脊髓解剖位置有关。了解脊髓圆锥末端的位置与蛛网膜下腔阻滞的关系对于避免和预防脊髓损伤尤为重要。
Several studies, in a large population groups, found that conus medullaris（CM） terminates at level from T12 to L3, utilizing magnetic resonance imaging （MRI）. The spinal cord termination level is related to age, sex, and spinal cord malformations. The risk of spinal cord injury increases in case the puncture point is higher than the level of L2、3. Several factors, such as identification of spinal space, the type of puncture needle, performance technique and the spinal cord anatomy, may be contributed to the occurrence of spinal cord injury Understanding the anatomical inconsistency of CM enables us to minimize suharachnoid block-induced spinal cord injury.
