In BriefIn this in vitro investigation, we compared the multidirectional flexibility properties of sacral alar iliac fixation with conventional methods of sacral and sacroiliac fixation using nondestructive and destructive investigative methods. The study demonstrated that S1-2 sacral fixation alone significantly increases sacroiliac motion under all loading modalities, while sacral alar iliac fixation reduced motion in axial rotation at the sacroiliac joint and offers potential advantages of a lower instrumentation profile and ease of assembly compared to conventional sacroiliac screw instrumentation.
在这项体外研究中，我们使用非破坏性和破坏性研究方法，比较了骶髂翼状螺钉固定与传统的骶骨和骶髂固定方法的多方向灵活性。研究表明，单独 S1-2 骶骨固定会显著增加所有加载模式下的骶髂关节活动度，而骶髂翼状螺钉固定可减少骶髂关节轴向旋转活动度，与传统的骶髂螺钉固定相比，其具有更低的器械轮廓和易于组装的潜在优势。
