In contrast to open reduction internal fixation, percutaneous fixation is a relatively new option for operative fixation of acetabular fractures. The techniques for percutaneous insertion of anterior and posterior column screws have been previously described. For technical aspects of retrograde percutaneous posterior column screws, much attention has been paid to the proper start point. However, descriptions of proper trajectory and end point have not been as clearly delineated. Understanding of posterior column anatomy and its radiographic correlates are fundamental in the safe placement of this screw. Herein, we present technical advice for acquisition and interpretation of fluoroscopic images needed to ensure a safe trajectory and end point in retrograde percutaneous posterior column screw placement. We highlight our steps to ensure correct placement in a small series.
与切开复位内固定相比，经皮固定是一种治疗髋臼骨折的新方法。经皮前柱和后柱螺钉固定技术已被先前描述。对于逆行经皮后柱螺钉的技术方面，人们非常关注正确的起始点。然而，对于正确的轨迹和终点的描述并没有那么清晰。理解后柱的解剖结构及其影像学相关性是安全放置此螺钉的基础。在此，我们提供了获取和解释透视图像的技术建议，以确保逆行经皮后柱螺钉放置的安全轨迹和终点。我们强调了我们的步骤，以确保在小系列中正确放置。
