The number of fusion surgeries increase each year which also increase the need for implant removal. In some cases, it can be extremely hard to remove a pedicle screw especially when there is a mismatch of the screw and the screwdriver. Also the screwdrivers can be contaminated during the operation, and this will cause a delay till the instruments are re-sterilized. There is a need for the removal of screws without special instruments. We describe a method for removing tulip-head polyaxial pedicle screws without special instruments. The screws are removed using an Allen key, a rod bender and a "U" shaped rod. We successfully removed 76 screws in 11 recent cases without any complications. The "U" rod technique is a simple and useful technique for the removal of tulip-head polyaxial screws.
融合手术的数量逐年增加，这也增加了植入物取出的需求。在某些情况下，特别是当螺钉和螺丝刀不匹配时，取出椎弓根螺钉可能极其困难。此外，螺丝刀在手术过程中可能会被污染，这将导致仪器重新消毒的延迟。因此，需要一种无需特殊器械即可取出螺钉的方法。我们描述了一种无需特殊器械即可取出郁金香头多轴椎弓根螺钉的方法。使用六角匙、杆弯器和“U”形杆来取出螺钉。我们成功地在 11 例近期病例中取出了 76 枚螺钉，没有任何并发症。“U”形杆技术是一种简单而有用的方法，可用于取出郁金香头多轴螺钉。
