摘　　要：目的：通过12～18岁青少年腰骶段椎间盘、椎管的解剖学结构 CT 影像学扫描和三维重建测量，探讨腰骶段椎间盘、椎管的发育规律及增龄变化规律特征，为青少年脊柱腰骶段疾病的诊断和治疗提供解剖学依据。方法选取我院30例12～18岁无腰椎疾患的青少年，均无外伤、神经症状和体征的双源64排螺旋 CT 薄层扫描影像学结果，扫描范围为腹盆腔，将获得腰骶段CT 原始图像数据以 DICOM格式导入 Mimics 三维重建软件进行相关指标测量，并进行统计学分析。结果青少年腰骶段椎间盘、椎管各径线在性别方面比较，差异无统计学意义（P ＞0．05），椎间盘、椎管各径线随着年龄的增长呈增长趋势，椎间盘、椎管各径线随着椎序列的增长呈波浪形变化趋势，且差异有统计学意义（P ＜0．05）。结论青少年腰骶段椎间盘、椎管解剖学参数呈规律性变化过程，但必须结合个体化影像学结果及生物力学、生物材料学等研究成果的支持，才能使腰骶段疾病治疗技术达到满意效果。Objective To study the developmental patterns and aging characteristics of anterior intervertebral disc and spinal canal based on anatomy CT scan and three dimensional reconstruction imaging measurement in the adolescents ages from 12 ~18 years old,and to provide the anatomical basis for the treatment and prevention of disc herniation diseases.Methods A total of 30 adolescents,who were with normal spines and without any the problems of nervous system,were selected to do CT scan of lumbosacral vertebrae through dual-source 64-slice spiral CT.CT original data of lumbosacral,which were translated into DICOMformat,were measured and analyzed statistically with Mim-ics software.Results There was no significant difference among the intervertebral disc and the superior sagittal diameter of the spinal canal, which were not influenced by gender （P 〉0.05）.The intervertebral disc and the superior sagittal diameter of the spinal canal would increase with age with wavy trends,and there were some significant differences（P 〈0.05）.Conclusion The anatomy parameters of lumbosacral disc and spinal changed regularly.In order to achieve satisfactory results of the lumbosacral disease treatment,it must be combined with individual radiographic findings,biomechanics and materials science,etc.
