Antegrade fixation of posterior column fractures of the acetabulum is challenging due to the narrow corridor and risk of screw misplacement. Although both antegrade and retrograde lag screws have been previously described for posterior column fracture fixation, the literature lacks a standardized technique for correct and safe screw placement, especially in an antegrade fashion. This technical note aims to optimize intraoperative images during posterior screw insertion using the antegrade technique, according to predetermined landmarks to save surgical time, decrease radiation exposition, and prevent surgical complications.
由于通道狭窄和螺钉错位的风险,髋臼后柱骨折的前向固定具有挑战性。虽然前向和后向拉力螺钉以前都曾被用于后柱骨折固定,但文献中缺乏一种标准化的技术来正确和安全地放置螺钉,特别是在前向方式下。本技术说明旨在根据预定的标志优化后螺钉插入术中的术中图像,以节省手术时间、减少辐射暴露并预防手术并发症。
