BACKGROUND Malcorrection of the acetabular fragment in periacetabular osteotomy (PAO) is associated with inferior outcomes. 2-dimensional radiographic parameters are being used for intraoperative verification of a satisfactory result. After reorientation of the fragment, the acetabular version must be verified with an intraoperative radiograph. In the case of an unsatisfactory correction, a reorientation would be required. A slim and radiation-free intraoperative navigation method to directly quantify the correction is highly desirable. AIM To find out whether the measurable angulation of the supraacetabular osteotomy can be used for this purpose. METHODS To determine the angulation, 13 consecutive patients who underwent a PAO were investigated. The preoperative and postoperative standard radiographs as well as CT scans were available. The surgically produced alteration of radiographic parameters was correlated to tilting and spreading of the supraacetabular osteotomy planes. RESULTS Tilting of the supraacetabular osteotomy planes correlates strongly to alteration of the lateral centre-edge angle (LCEA) and the acetabular index (ACI), whereas spreading of the same planes showed also a strong correlation, but to the LCEA only. 1° of tilting resulted in a 0.2° alteration of the LCEA and a 0.5° alteration of the ACI, whereas 1° of spreading resulted in a 0.5° alteration of the LCEA. CONCLUSIONS This study shows that the measurable angulation of the supraacetabular osteotomy planes can be used to monitor the three-dimensional reorientation of the acetabular fragment in PAO. As long as sophisticated modalities are lacking, this technique offers an easy way to intraoperatively navigate the correction in PAO.

髋臼周围截骨术:髋臼上截骨术的角度用于量化校正。

背景 髋臼周围截骨术 (PAO) 中髋臼碎片的矫正不良与较差的结果相关。二维放射线摄影参数用于术中验证满意的结果。重新定位碎片后,必须通过术中放射线照片验证髋臼版本。如果修正效果不理想,则需要重新定位。非常需要一种纤薄且无辐射的术中导航方法来直接量化校正。目的 探讨髋臼上截骨术的可测量角度是否可用于此目的。方法 为了确定角度,对 13 名连续接受 PAO 的患者进行了调查。提供术前和术后标准X光片以及CT扫描。手术产生的放射线参数的改变与髋臼上截骨平面的倾斜和扩展相关。结果 髋臼上截骨平面的倾斜与外侧中心边缘角 (LCEA) 和髋臼指数 (ACI) 的变化密切相关,而同一平面的扩展也显示出很强的相关性,但仅与 LCEA 相关。1° 倾斜导致 LCEA 0.2° 变化和 ACI 0.5° 变化,而 1° 展开导致 LCEA 0.5° 变化。结论 本研究表明,髋臼上截骨平面的可测量角度可用于监测 PAO 中髋臼碎片的三维重新定向。只要缺乏复杂的模式,该技术就提供了一种在术中导航 PAO 矫正的简单方法。
