Osteotomies allow the restoration of appropriate sagittal alignment; however, closure of osteotomies can be challenging. Typical closure involves compressing pedicle screw heads across the rods, potentially causing screw loosening and failure. Motorized hinged operating tables are often used to assist with controlled closure of osteotomies without manual compression, but there is no published research quantifying the amount of correction provided solely by changes in the table angle.

铰接手术台是否有助于史密斯-彼得森截骨术中经椎间孔腰椎椎间融合术的矢状矫正？射线照相分析。

截骨术可以恢复适当的矢状排列；然而，截骨术的闭合可能具有挑战性。典型的闭合涉及将椎弓根螺钉头压过杆，可能导致螺钉松动和失效。电动铰接手术台通常用于辅助截骨术的受控闭合，无需手动压缩，但没有已发表的研究量化仅通过手术台角度变化提供的校正量。
