摘要

随着内固定在脊柱手术中的应用越来越普遍,翻修手术的需求也在增加。在翻修手术中,最困难的步骤之一是拆除多轴椎弓根螺钉,特别是在没有合适的翻修装置的情况下。我们在此介绍一种简单的多轴螺钉拆卸方法。离开或放置一小块杆,用螺母牢牢地连接在一起,拧紧多轴螺钉的头部。它不能再从螺钉的远端自由移动,螺钉可以用大钳或针钳逆时针旋转,这在几乎所有的手术装置中都是可用的。

Poly-axial screw removal.

As the use of instrumentation in spinal surgery has become common, the need for revision surgery has increased. During revision surgery one of the most difficult steps is removal of poly-axial pedicle screws, especially if no suitable revision set is available. We describe here an easy method for poly-axial screw removal. Leaving or placing a small piece of rod, attached firmly by a nut, tightens the head of the poly-axial screw. It can no longer move freely from the distal part of the screw and the screw can be removed by turning it counterclockwise with a big clamp or needle driver, which is available in almost every surgery set.
