For most cases, the union of fracture was accomplished by decollement of bone cortex pedicle and firm internal fixation without bone graft.
绝大部分经带蒂骨皮质剥离和坚强内固定术后而愈合，不需植骨。
Objective: Cortex thicknesses of subaxial cervical pedicle entrys circumferential structures were measured on planar ct images to provide quantitative data for cervical pedicle screw insertion.
目的：对下颈椎椎弓根四壁及入口毗邻结构的皮质厚度行影像学测量，为临床椎弓根钉植入提供参考。
Conclusion: The thinnest lateral cortex is one cause of pedicle screw penetration.
结论：椎弓根外侧骨皮质最薄，可能是导致椎弓根皮质破裂的原因。
