RESEARCH AND DESIGN: A retrospective, clinical, non-randomized, controlled study. OBJECTIVE: To evaluate the application of a new spinal navigation robot on percutaneous vertebroplasty (PVP) under local anaesthesia. METHODS: The result of inserting the puncture needle into the simulated pedicle was observed in vitro. Thirty patients with thoracolumbar fractures were enrolled. The basic data, operation-related data and clinical effect scores were recorded. The learning curve of robot-guided surgery was analysed. RESULTS: The maximum yaw angle of the puncture needle implanting into the simulated pedicle is 0.5°. The operation time (33.93 ± 5.97 min vs. 53.75 ± 14.08 min, p = 0.000) and the average X-ray exposure time (31.43 ± 4.93 s vs. 54.69 ± 2.15 s, p = 0.000) was significantly less in the robot group. The surgeons quickly mastered the technique of robot-guided pedicle puncture after three surgeries. CONCLUSIONS: Robot-assisted PVP could performed under local anaesthesia with the new robot.
