A simple technique for removing broken pedicle screws.

Complications such as pseudoarthrosis and fracture of the rod and pedicle screw may develop after spinal fusion operations. 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.
