Abstract
Several studies, in a large population groups, found that conus medullaris (CM) terminates at level from Ti_(12) to L_3, 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 L_(2、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 subarachnoid block -induced spinal cord injury.
