Abstract: [Objective] To compare the safety and accuracy of Renaissance robot assisted pedicle screw placement versus freehand technique in lumbar revision surgery. [Methods] A retrospective study was conducted on 69 patients who had lumbar revision surgery from January 2018 to December 2018. Among them, 31 patients had revision surgery performed with Renaissance robotic system assisted pedicle screw placement, whereas the remaining 38 patients were with traditional freehand pedicle screw placement. The documentations were compared between them, including the early clinical outcomes and the accuracy of pedicle screw placement measured on CT scans based on Gertzbein Robbins grading. [Results] Although there were no significant differences in operative time and complications between the two groups (P>0.05) , the robot assisted group had significantly less intraoperative bleeding and the frequency of fluoroscopy than the freehand group (P<0.05) . In the robotic assisted group, a total of 152 screws were inserted, which were marked as grade A in 137, grade B in 11, grade C in 4 grade and no grade D or E in any screws with accuracy rate of the screws placement of 97.37% (148/152) . By comparison, 194 screws were placed in total in the freehanded group, which were rated as grade A in 129, grade B in 48, grade C in 15, grade D in 2 and no grade E in any screw, with accuracy rate of screw placement of 91.24% (177/194). The robot assisted technique was statistically superior to the freehand method in the accuracy of screw placement (P<0.05) . [Conclusion] This Renaissance robot assisted pedicle screw placement has advantages of higher accuracy, less intraoperative bleeding and less intraoperative fluoroscopy over the traditional freehand screw placement.
