A biomechanical cadaveric analysis of polymethylmethacrylate-augmented pedicle screw fixation

Abstract

Polymethylmethacrylate-augmented pedicle screw fixation results in a significant increase in the axial pullout strength of augmented pedicle screws in both primary and revision procedures. This technique may be a valuable adjunct in cases in which bolstering of the screw-bone interface is necessary.
