Advanced Intraoperative Imaging Techniques to Enhance Surgical Precision in Spine Procedures

Background: Advancements in intraoperative imaging techniques have revolutionized spine surgery by enhancing surgical precision, reducing complications, and improving patient outcomes. Objective: To evaluate the impact of advanced intraoperative imaging techniques on surgical precision and patient outcomes in spine procedures, with a focus on real-time imaging integration. Methods: This prospective study included 188 patients who underwent spine surgery at the Department of Neurology and Clinical Neurosciences, Northwestern University Feinberg School of Medicine, from January 2022 to June 2023. The patients were divided into two groups: one using traditional fluoroscopy and the other using advanced intraoperative imaging systems (CT, MRI, and AR navigation). Surgical precision was assessed by evaluating the placement of spinal instrumentation and intraoperative complications. Statistical analysis included t-tests for comparison between groups, with significance set at p<0.05. Standard deviation (SD) was used to measure variability in outcomes. Results: The group using advanced imaging techniques showed a 35% improvement in the accuracy of spinal instrumentation placement (p-value=0.03). The complication rate in the advanced imaging group decreased by 27%, with a 23% reduction in neurological complications. The SD for intraoperative screw placement in the traditional group was 5.2 mm compared to 2.1 mm in the advanced imaging group, indicating a significant improvement in surgical precision. Overall, the advanced imaging group had a 42% faster surgery time (mean time 155±10.4 minutes vs 270±15.3 minutes in the traditional group). Postoperative recovery time was also reduced by 19%. Conclusion: Advanced intraoperative imaging techniques significantly enhance surgical precision, reduce complications, and shorten recovery time in spine procedures, highlighting their importance in modern spinal surgery.
