Comparison and prediction of pullout strength of conical and cylindrical pedicle screws within synthetic bone

BACKGROUND: This study was designed to derive the theoretical formulae to predict the pullout strength of pedicle screws with an inconstant outer and/or inner diameter distribution (conical screws). For the transpedicular fixation, one of the failure modes is the screw loosening from the vertebral b...
