颈椎间盘与脊髓和神经根的对应关系及其临床意义

The relationship of the cervical discs with its corresponding spinal cords and nerve roots

目的：弄清颈椎间盘与脊髓及神经根的对应关系，探讨颈椎间盘突出症的致病机理。方法：对１４例成人颈椎标本的椎间盘、脊髓及神经根进行了解剖观测。结果：纵向上，各椎间盘对应低２～３个序数的脊髓节；横向上，椎间盘后缘位于两侧钩椎关节后内缘之间且窄于所对脊髓。结论：各间盘对应低２～３个序数的脊髓节，不与神经根相邻。

Objective:To clarify the rlationship of the cervical discs with its corresponding spinal cords and the nerve roots,to investigate the pathogenesis of the cervical discs herination.Methods:The relationship of the cervical discs with the corresponding spinal cords and the nerve toots were observed and measured on 14 adult cadaver cervical specimens.Results:In sagittal section,C x disc was coresponding to C x+2～3 spinal cord segment and its ventral root.In transverse section,the posterior margin of the disc is located between the posterior internal edges of bilateral Luschka joint,and narrower than its corresponding spinal cord.Conclusions:Every disc corresponds to next 2 ordinal number spinal cord segment and doesn′t adjoin the nerve root with the separation of Luschka joint.
