目的探讨颈椎椎弓根进钉参数与棘突的三维关系,为经皮椎弓根螺钉内固定及器械的设计提供参考。方法20例健康成人颈椎CT重建模型导入UG imageware 13.2,以70%、80%、90%边界深度为研究基础,测量椎弓根通道进钉螺钉半径、外偏角、通道长度(L)、通道与矢状面、水平面的角度;进钉轴与冠状面的交点与椎弓根的角度。B、C点到参考平面、棘突的距离。结果(1)C_(3~7)椎弓根通道内切圆半径在2.79~3.89 mm之间。(2)通道长度、外偏角随着边界深度的增加而增大。(3)C_(3~7)的Ac最大值出现在70%边界深度。(4)B点到正中矢状面、冠状面的距离都随着边界深度增加而增大。(5)B点、C点棘突末端的距离随着边界深度增...

Objective To study the entry point of cervical pedicle screw insertion and its three- dimensional relationship of the spinous process, and to provide anatomical basis for percutaneous cervical pedicle screw fixation and the design of the aiming device. Methods 3D models were imported into UG13.2 imageware for measurement. We took the 70% ,80% and 90% as our research foundation, and several measurements were conducted, including the biggest inscribed circle radius（R）, the lateral angle（Ap） and the length of pedicle insertion channel（L）.The...
