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.
