Most reports regarding hardware removal involve the violation of the cortex to allow a specialized to tool to extract a retained fragment. This leaves large, unfilled screw holes that act as stress risers for months postoperatively. This article describes a novel technique to remove a retained intracortical screw fragment during total hip arthroplasty. Conversion of an intertrochanteric osteotomy to a total hip arthroplasty can be made more difficult by anatomical changes to the femur and retained hardware. Direct access to the intramedullary canal during total hip arthroplasty allowed for the safe removal of a retained intracortical screw using this technique.
大多数关于取出内固定物的报告都涉及破坏皮质，以便使用专门工具取出残留碎片。这会留下大的、未填充的螺钉孔，在术后数月内成为应力集中点。本文介绍了一种在全髋关节置换术中取出残留皮质内螺钉碎片的新技术。股骨的解剖结构变化和残留的内固定物会使转子间截骨术转换为全髋关节置换术变得更加困难。在全髋关节置换术中直接进入髓腔，使用该技术可安全取出残留的皮质内螺钉。
