摘要
我们报告一例20多岁女性股骨粗隆下截骨不愈合的交换股骨钉手术中股骨头牵引螺钉“冷焊接”到髓内钉(IMN)。我们随后开发了一种反向螺旋槽螺栓提取插座,设计用于接合螺栓或螺钉的外壁。1周后,从Smith and Nephew Meta-Tan IMN中取出螺钉,成功完成交换钉固定。本病例报告描述了在复杂翻修中使用冷焊股骨头拉力螺钉的技术挑战情况。本文介绍了一种用于此类病例的新型拔除装置和技术。
Removal of a 'cold-welded' femoral head lag screw in a nail combination.
We present a case of a femoral head lag screw 'cold welded' to an intramedullary nail (IMN) in a female in her 20s during exchange femoral nailing of a subtrochanteric femoral osteotomy non-union. We subsequently developed a reverse spiral-fluted bolt extraction socket, designed to engage the outer wall of a bolt or screw. The lag screw was removed from the Smith and Nephew Meta-Tan IMN, 1 week later, and exchange nailing was successfully completed. This case report describes a technically challenging situation of a cold-welded femoral head lag screw during a complex revision. This report introduces a novel removal device and technique for such cases.
