Comparison of novel machine vision spinal image guidance system with existing 3D fluoroscopy-based navigation system: a randomized prospective study.

研究概要

90 patients with a spinal pathology scheduled for an open posterior lumbar fusion with pedicle screw implantation were randomized to receive screw placement performed using a novel stereoscopic guidance system (FLASH Navigation; n=45) or a 3D fluoroscopy-based navigation system (n=45). Outcomes of interest included intra-operative fluoroscopy time and dose, postoperative radiation levels, pedicle screw accuracy, blood loss, and revision rate. The FLASH Navigation system resulted in significantly lower intra-operative radiation time and dose, greater screw placement accuracy, and lower postoperative radiation levels vs. 3D fluoroscopy-based screw placement. No cases of revision were reported.
