    The study introduces a visual tracking guide template (VTGT) for augmented reality navigation in surgical training.

  • 2

    Junior residents used the VTGT to simulate pedicle screw placement on spine models with K-wires.

  • 3

    The average time for placing each K-wire was 36.4 seconds, with a user experience score of 87.8 points.

  • 4

    Measured navigation errors included a deviation value of entry point (DVEP) of 2.20 mm and a deviation value of trajectory angle (DVTA) of 2.30°.

  • 5

    All screws placed during the study met the clinical safety requirements according to the Gertzbein-Robbins scale.
