我们尝试确定上关节突基部相对于椎弓根中心的空间方向，然后使用理想的椎弓根螺钉入口点（外侧三分之一和内侧三分之二交界处的上关节突基部）测量横向和矢状螺钉角度。该技术的优点是易于识别的进入点、明确的横向和矢状螺钉角度以及内侧和下椎弓根侵犯的发生率非常低。
We have attempted to determine the spatial orientation of the base of the superior articular process in relation to the centre of the pedicle and then measure the transverse and sagittal screw angles using this ideal pedicle screw entry point - the base of the superior articular process at the junction of the lateral one-third and medial two-thirds. The proposed advantages of this technique are the easily identifiable entry point, the well-defined transverse and sagittal screw angles and a very low incidence of medial and inferior pedicle violation.
