Clinical Report: Improving Pedicle Screw Placement Training Using a Visual Tracking Guide Template in Augmented Reality Navigation
Overview
This study evaluates the feasibility of a visual tracking guide template (VTGT) for augmented reality (AR) navigation in surgical training for pedicle screw placement. Results indicate that the VTGT is effective in reducing navigation errors and enhancing user experience among junior residents.
Background
Spinal fusion surgery has seen a significant increase in procedures, necessitating improved training methods for junior surgeons. The complexity of pedicle screw placement, due to anatomical variability and proximity to vital structures, underscores the need for enhanced training tools. Augmented reality (AR) technology presents a promising avenue for improving surgical training and accuracy.

Key Findings
The VTGT was used for real-time tracking of AR images during pedicle screw placement.
Five junior residents participated, placing a total of 100 K-wires.
All screws met clinical safety requirements according to the Gertzbein-Robbins scale.
The average user experience score was high at 87.8 points.
The navigation error metrics (DVEP and DVTA) were within acceptable ranges.
Clinical Implications
The findings suggest that VTGT-based AR navigation can enhance the training experience for junior residents in pedicle screw placement. This technology may contribute to improved surgical outcomes by reducing navigation errors.
Conclusion
The study demonstrates that the VTGT-based AR navigation technology is feasible and beneficial for training in pedicle screw placement, potentially enhancing surgical education.
