BACKGROUND: The aim of this study was to compare intraoperative and postoperative outcome between a robot-assisted vs. a navigated transpedicular fusion technique.
METHODS: This retrospective analysis included patients who underwent transpedicular posterior fusion of the spine due to trauma, pyogenic spondylodiscitis and osteoporosis. Surgery was done either with a robot-assisted or a percutaneous navigated transpedicular fusion technique. The outcome analysis included the duration of surgery, the radiation exposure, the postoperative screw position and complications.
RESULTS: Sixty patients were operated and 491 screws were analysed in total. No statistical difference was seen in the applied cumulative effective radiation dose per patient. Radiological assessment revealed a more accurate screw placement with robot-assistance. A learning curve could be observed in the robot-assisted fusion.
CONCLUSIONS: Robot-assisted and navigated transpedicular fusion techniques are both effective and safe. Robot-assisted transpedicular spine fusion goes along with higher placement accuracy but its implementation needs an adequate learning curve. This article is protected by copyright.
