Augmented Reality Navigation System Enhances the Accuracy of Spinal Surgery Pedicle Screw Placement: A Randomized, Multicenter, Parallel-Controlled Clinical Trial.

ABSTRACT:

Objective

The pedicle screw insertion technique has evolved significantly, and despite the challenges of precise placement, advancements like AR-based surgical navigation systems now offer enhanced accuracy and safety in spinal surgery by integrating real-time, high-resolution imaging with virtual models to aid surgeons. This study aims to evaluate the differences in accuracy between novel AR-guided pedicle screw insertion and conventional surgery techniques.

Methods

A randomized controlled trial was conducted from March 2019 to December 2023 to compare the efficacy of AR-guided pedicle screw fixation with conventional freehand surgery using CT guidance. The study included 150 patients, aged 18-75, with 75 patients in each group. The total number of pedicle screws planned fo
