背景:由于颈椎弓根螺钉独特的三维稳定性和高风险性,临床工作需要更完善的解剖学研究. 目的:测量颈椎弓根和毗邻结构之间的量化关系值,为在颈椎弓根内安全置钉提供帮助,以减少并发症. 方法:在15具经福尔马林防腐处理的尸体上,去除颈椎棘突,椎板,相关韧带及侧块,上、下关节突,暴露出颈椎弓根的狭窄部及毗邻的神经组织.直接测量椎弓根内壁与硬膜囊的距离(PDSD)、椎弓根狭窄部内壁间的距离(IPD)以及该节段硬膜囊横径(DSW). 结果:15具标本中,PDSD:0~6.2 mm,IPD:21.0~25.4 mm,DSW:13.5~18.3 mm.男女之间有差异.并图示了硬膜外静脉丛与椎弓根的关系. 结论:大多数情况下,颈椎弓根与毗邻的神经结构之间存在一定的距离.向颈椎弓根的内、上方置入椎弓根螺钉是相对安全的.

@@@@Background: Considering the unique three dimensional structure and high risks of cervical pedicle screws, we need detailed anatomic research on cervical vertebrae. @@@@Objective: To measure accurate anatomic distances between the cervical vertebrae and adjacent neural structure so as to avoid and minimize complications of pedicle screw implantation. @@@@Methods: Fifteen cadavers were used for dissection to observe the relationship between the cervical spine and adjacent neu-ral structure. After removal of whole posterior bony element of the cervical spine, the isthmus of the pedicles, the nerve roots of C3-C7 and the dural sac were exposed. Pedicle-dural sac distance (PDSD), interpedicular distance (IPD), and dural sac width (DSW) were measured directly. @@@@Results: In 15 cadavers, PDSD, IPD and DSW were 0-6.2 mm, 21.0-25.4 mm and 13.5-18.3mm, respectively. There was sig-nificant difference in above indice between men and women. The relationship between the epidural venous plexus and cervi-cal pedicle was explained. @@@@Conclusions: There is some space between the cervical pedicle and its adjacent neural structure in common. It seems safe to place the pedicle screw in the cervical pedicles inward and upward.
