Thoracic pedicle screw fixation under axial and perpendicular loadings: A comprehensive numerical analysis

The screw diameter and amount of cortical bone left around the entry point are essential for pedicle screw fixation in all loading scenarios. The proximity of the screw threads to the cortical bone (pedicle fill) has a major role in pedicle screw fixation.
