Complication with Removal of a Lumbar Spinal Locking Plate

Figure 2

Photograph of the plate after removal, demonstrating the cold welding of the screw head to the plate (top screw: this was the one release with a peripheral burr cut, top right hole of plate), the trajectory of the burr holes made to release the plate (middle two screws, requiring burr cuts from the center of the plate to each hole, bottom two holes), and the cold weld of the reverse threaded screw driver to the screw head (bottom screw, top left hole).
