    The study analyzed 105 patients with thoracolumbar fractures who underwent percutaneous pedicle screw fixation using two navigation systems.

  • 2

    The 2D-navigation group had shorter operative times and lower radiation doses compared to the 3D-navigation group.

  • 3

    Screw placement accuracy was similar between the 2D and 3D navigation groups, with rates of 99.2% and 98.1%, respectively.

  • 4

    Both navigation methods resulted in significant postoperative improvements in visual analog scale and Oswestry Disability Index scores.

  • 5

    CUSUM analysis indicated that proficiency was achieved earlier with the 2D navigation system than with the 3D system.
