Precision insertion of percutaneous sacroiliac screws using a novel augmented reality-based navigation system: a pilot study.

Purpose: Augmented reality (AR) enables superimposition of virtual images onto the real world. The aim of this study is to present a novel AR-based navigation system for sacroiliac screw insertion and to evaluate its feasibility and accuracy in cadaveric experiments.

Methods: Six cadavers with intact pelvises were employed in our study.
