摘　　要：目的:通过对14~18岁青少年C_(3~7)椎弓根C_T影像学扫描,探讨其椎弓根的发育规律和特征,为青少年C_(3~7)椎弓根内固定诊治提供影像学依据。方法:选取青少年下颈椎64排螺旋C_T影像学资料20例,将获得的原始数据导入Mimics三维重建软件行相关指标测量与统计分析。结果:青少年下颈椎椎弓根髓腔的各测量指标在性别与侧别间均无差异(P>0.05),椎弓根髓腔高、宽和有效钉道长指标呈递增趋势,C_3、C_4和C_7椎弓根髓腔高、髓腔宽有统计学意义(P<0.05),C_4、C_5和C_7的E角有统计学意义及C_4、C_5、C_6和C_7的F角有统计学意义(P<0.05)。结论:青少年下颈椎椎弓根解剖学参数有明显的规律性,选择合适直径的螺钉,才能使椎弓根内固定技术达到满意效果。Objective:To analyze the aging characteristics and significance of subaxial cervical vertebra pedicle morphology in the 14~18 adolescent with CT image and to providing basis imaging and developmental pattern of pedicles in subaxial cervical vertebrae adolescent for pedicle fixation.Methods:The 20 adolescents with normal cervical vertebra were selected to do spiral CT scan.The original data imported into the Mimics software were to measure and analyze statistically the relevant indicators.Results:There was no significant difference in the result of the subaxial cervical vertebra pedicle,which were not influenced by bilateralism and gender(P>0.05).The subaxial cervical vertebra pedicle morphology enerally showed an increasing trend with increasing age.The height and width of C 3 and C 4 vertebra pedicle had significant differences with the C 7 vertebra(P<0.05);The E angle of C 4 and C 5 vertebra pedicle had significant differences with the C 7 vertebra and the F angle of C 4、C 5 and C 6 vertebra pedicle had significant differences with the C 7 vertebra(P<0.05).Conclusion:The anatomy morphology of subaxial cervical vertebra pedicle changed regularly.In order to satisfactory results of the pedicle-screw technique,it must be selected with the suitable screws.
