MATERIAL and METHODS: The preoperative, intraoperative and postoperative data for 27 patients were reviewed. To reveal the effect of a learning curve, the cases were divided into two groups: Group A and Group B The clinical data and radiological data were compared with the values obtained from preoperative planning.

RESULTS: The patients consisted of 23 females and 4 males. A total of 136 screws were placed in the 27 cases. The accuracy rate of the screw positions was 98.5%. The overall mean procedure duration was 73.2 minutes for Group A and 46.1 minutes for Group B. The overall mean x-ray exposure time per screw was 1.3 seconds, 1.8 seconds for Group A and 0.9 seconds for Group B. Postoperative imaging revealed that 126 screws were perfect, screw malposition of <2mm was observed for 8 screws, and malposition of >2mm was observed for 2 screws.

CONCLUSION: Robotic spine surgery provides a high degree of accuracy for pedicle screw placement and allows for reduced radiation exposure. Keywords : Robotic spine surgery, Pedicle screws, Radiation exposure, Pedicle screws accuracy
