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.
我们试图确定上关节突基部相对于椎弓根中心的空间方位，然后使用这个理想的椎弓根螺钉进针点——外侧三分之一与内侧三分之二交界处的上关节突基部，来测量横向和矢状面螺钉角度。该技术的预期优势在于进针点易于识别、横向和矢状面螺钉角度明确，以及内侧和下侧椎弓根侵犯的发生率极低。
