Percutaneous pelvic screw placement is a technically demanding procedure. A precise intraosseous pathway must be prepared before screw placement into any osseous fixation pathway of the pelvis. Adjustments to a drill or guidewire become increasingly difficult as the instrument is advanced within the pelvis. We present a reliable and reproducible technique using a 2.0 mm guidewire that allows for correction of an initially misdirected drill within the pelvis. This technique also allows for manipulation and reduction of certain malaligned pelvic fractures prior to percutaneous cannulated screw placement. This technique does not substitute for poor surgical technique but is used to optimize the position of percutaneously placed pelvic screws.
经皮骨盆螺钉固定是一项技术要求很高的手术。在将螺钉固定到骨盆的任何骨固定路径之前,必须准备精确的骨内通道。随着器械在骨盆内推进,钻头或导丝的调整变得越来越困难。我们提出了一种可靠且可重复使用的技术,使用 2.0 毫米导丝,可在骨盆内纠正最初定向错误的钻头。该技术还允许在经皮套管螺钉固定之前对某些错位的骨盆骨折进行操作和复位。该技术不能替代不良的手术技术,但用于优化经皮放置的骨盆螺钉的位置。
