No screw-related complications or revision occurred in the present study.Ĭonclusion The outcome of screw accuracy of this robotic system was comparable with that of experienced surgeons, and no screw-related complication was found in the RA group during hospitalisation. The radiation time per screw is significantly lower in the RA group. No statistical difference was found in the operation time, radiation time per case, and length of stay between both groups. In the FH group, 78.0 of screws were Grade A, 20.0 were Grade B, and 2.0 were Grade C. In the RA group, 90.6 of screws placed were Grade A, and 9.4 were Grade B. Result A total of 82 pedicle screws were placed in the 17 participants. Other variables included operation time, radiation time, length of stay, and screw-related complications. Precision was measured by the entry point deviation distance and the trajectory rotation. Seven (3 M4 F) were randomly assigned to the robot-assisted group (RA group), and the other ten (4 M6 F) were assigned to the conventional technique group (FH group).Īccuracy of screw insertion was determined using the Gertzbein and Robbins Scale. Methods and materials A randomised controlled trial was conducted for 17 participants who were required posterior lumbar interbody fusion process. Higher Grade Fixation Software Trial Was Conducted The aim of this study is to evaluate the feasibility and safety in pedicle screw insertion of posterior lumbar interbody fusion assisted by this novel robotic system. In the present study, a novel spinal robotic system with automatic drilling power was introduced.

Higher Grade Fixation Software Trial Was Conducted.
