目的：通过对12~18岁少年腰骶段椎弓根影像学扫描和三维重建，探讨腰骶段椎弓根的发育规律和增龄特征，为青少年脊柱疾病的诊治和预防提供影像解剖学依据。方法选取我院少年患者30例，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，扫描范围为盆腹腔，将获得腰骶段CT原始数据以DICOM格式导入三维重建软件进行相关指标测量，并按性别、年龄分组进行统计分析。结果少年腰骶段椎弓根的高、宽和钉道长在性别与侧别间均无显著性差异(P>0.05)，发育总体随着年龄和椎序的增长呈递增趋势，且存在一定的显著性差异。结论少年脊柱椎弓根及相关结构解剖学参数呈规律性变化过程，临床应用时可做参考，但必须结合个体化影像学结果及组织逆向成型技术及生物力学研究成果的支持，才能使椎弓根内固定技术达到个体化治疗的满意效果。

Objective To study the developmental patterns and aging characteristics of lumbar pedicle morphology in the adolescents aging from 12~18 years old,and to provide the anatomical basis for image and three-dimensional analysis of the treatment and prevention of spinal diseases. Methods the 30 adolescents with normal spines and without any the problems of nervous system were selected to do thin spiral CT scan that the range was lumbar. The original data imported into three-dimensional reconstruction software with the form of DICOM were to measure and analyze statistically the relevant indicators according to gender and age. Results There was no significant difference in the pedicle height,pedicle width and length of form screw entry point to vertebral anterior cotrex,which were not influenced by age and gender (P>0. 05). The physical development of human increases gradually with age and has some significant differences. Conclusion A regular change process is displayed to provide references for clinic. But it must be combined with the results of individual imaging and the technology of reverse engineering and the support of rapid prototype manufacturing. Only in this way can it meet the satisfaction of individualized treatment.
