Removing a broken pedicle screw is not always easy. Different methods and tools have been developed to remove the broken screw. Preserving the pedicle is an advantage for re-instrumentation. The head of the broken screw can be modified with the aid of a high-speed drill and the screw can be removed using a fractured screw removal tool without any problems. In addition, performing this procedure under the microscope reduces the risk of injury in the surrounding dura mater and the root. We believe that this simple technique can be conveniently used while removing a broken pedicle screw.
取出折断的椎弓根螺钉并非总是易事。人们已经开发出不同的方法和工具来取出折断的螺钉。保留椎弓根对再次手术器械操作有利。借助高速钻头可对折断螺钉的头部进行修整,然后使用折断螺钉取出工具就能顺利取出螺钉。此外,在显微镜下进行该操作可降低损伤周围硬脑膜和神经根的风险。我们认为这种简单技术在取出折断的椎弓根螺钉时可方便地使用。
