目的：通过对12~18岁青少年腰骶段椎弓根影像学扫描和三维重建,探讨腰骶段进钉角的增龄变化规律,为青少年脊柱内固定治疗提供解剖学依据。方法选取我院青少年患者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、年龄分组进行统计学分析。结果青少年腰骶段椎弓根 E、F 角及椎体复合体的上下及左右入钉点间距在性别与侧别间均无显著性差异(P>0.05),E、F角及椎体复合体的上下入钉点间距发育总体随着年龄和椎序的增长呈增长趋势,且存在一定的显著性差异。结论青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 pedicle of lumbosacral developmental patterns and aging characteristics by means of studying the ado-lescents aging from 12~18 years old,and provide the basis for image and three-dimensional analysis of the treatment of spinal diseases. Meth-ods Select the 30 normal spines of adolescents without any the problems of nervous system,who did thin spiral CT scan of lumbosacral verte-brae. The original data in the form of DICOM were put into three-dimensional software to do the relevant measurement and analyzed according to gender and age. Results There were no significant differences between the pedicle of lumbosacral E/F angle and DSP /DNP and these differ-ences were not influenced by age and gender(P>0. 05). The physical development of human increases gradually with age and has some signifi-cant differences. Conclusion A regular change process and operation in the region value in patients with lumbarsacrum is displayed. But it must be combined with the results of individual imagine and the technology of reverse engineering and the support of rapid prototype manufactur-ing. Only in this way can it meet the satisfaction of individualized treatment.
