Use of O-arm navigation in percutaneous pedicle screw fixation for thoracolumbar fractures in patients with ankylosing spinal disorders: reducing intraoperative radiation exposure—a retrospective cohort study

O-arm navigation markedly reduces intraoperative radiation exposure without compromising pedicle screw accuracy in ASD-related thoracolumbar fractures. Given the substantial occupational radiation risks faced by spine surgeons, O-arm navigation represents a valuable tool for improving radiation safety while maintaining surgical precision. Larger prospective studies are warranted to validate these findings.
