A Single-Center Experience of Robotic- Assisted Spine Surgery of 150 cases: Analysis of Screw Accuracy, Superior Facet Joint Violation

Objective: As technology advances and allows for even more efficiency and precision, it is anticipated that robot-assisted spine surgery will become more and more prevalent in the future. In the realm of spine surgery, we discuss our preliminary experiences with the Excelsius GPS® spine surgical robot and its role in improving patient safety. Methods: At our facility, 150 patients had robot-assisted Transforaminal Lumbar Interbody Fusion (TLIF). The demographic information, radiation exposure, cranial facet joint violation, and pedicle screw accuracy were assessed. Pedicle screw accuracy was evaluated using the Gertzbein-Robbins classification, whereas facet joint violation was evaluated using the Yson classification. Results: 150 patients received robotic help for the placement of 696 screws in all. With robotic aid, we discovered the accuracy to be 98.27% and facet joint violation rates of 17% & 0% for grades 1 & 2 respectively. Radiation exposure for patients was significantly higher than that of healthcare personnel, (10.57±3.605 vs 1.35±0.425 mSv P<0.00001). Conclusion: Robotic spine surgery may reduce human error—such as tremors and fatigue—that may occur during traditional open spine procedures. Robotic surgery offers three-dimensional views and navigation technology and may be used to improve accuracy, lower issues, and raise patient safety.
