Ultrasonography (US) is the most non-invasive, safe, and, especially in the period of infancy, best method for visualizing and examining the spinal cord. Furthermore, US is the primary work-up for development of the spinal canal, and for follow-up on issues relating to subcutaneous tissues, bone development, and the spinal cord. Conus medullaris terminates at the second lumbar vertebra, according to a consensus in the literature.
Healthy children under the age of 6 months who were admitted to the radiology clinic for routine USG follow-ups between the dates of March 2012 to December 2014 were included in this study.
Our study includes data from 1125 lumbosacral ultrasounds. The terminal point of the conus level of the attended infants, superior, middle part, inferior of the vertebrae L1, L2, and L3. Furthermore, the termination of the discal distance ratio did not differ significantly between genders.
Therefore, according to our results, gender is not an influencing factor in the termination of the spinal cord. Based on the study we performed, as well as the previous literature, in infants without a recognized spinal pathology, the spinal cord is detected below the vertebra L3.
超声检查（US）是最无创、安全的检查方法，尤其在婴儿期，是可视化和检查脊髓的最佳方法。此外，US是椎管发育以及皮下组织、骨骼发育和脊髓相关问题随访的主要检查手段。根据文献共识，脊髓圆锥终止于第二腰椎。
本研究纳入了2012年3月至2014年12月期间因常规超声随访而入住放射科门诊的6个月以下健康儿童。
我们的研究包括1125次腰骶部超声检查的数据。所检查婴儿的脊髓圆锥水平终点位于L1、L2和L3椎体的上、中、下部分。此外，性别之间椎间盘距离比值的终点无显著差异。
因此，根据我们的结果，性别不是脊髓终止的影响因素。基于我们所进行的研究以及先前的文献，在没有公认脊髓病变的婴儿中，脊髓在L3椎体以下被检测到。
