Implications of navigation in thoracolumbar pedicle screw placement on screw accuracy and screw diameter/pedicle width ratio

open access: yesBrain and Spine, 2023
Introduction: There is ample evidence that higher accuracy can be achieved in thoracolumbar pedicle screw placement by using spinal navigation. Still, to date, the evidence regarding the influence of the use of navigation on the screw diameter to pedicle

Biomechanical Study of Pedicle Screw Fixation Comparing Intracortical Pedicle Screw and Oversized Pedicle Screw. [PDF]

open access: yesSpine Surg Relat Res
Pedicle screw placement can be technically challenging in anatomically narrow pedicles, such as those in the thoracic spine or in older patients. Although smaller screws preserve cortical integrity, they may compromise fixation strength. Conversely, oversized pedicle screws that breach the pedicle cortex may enhance anchorage but raise concerns about ...
