However, few studies have compared the accuracy and efficiency of these two techniques. Thus, the purpose of this study is to compare the accuracy and efficiency of robotic and navigation-assisted screw placement in the spinal vertebrae.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The 24 spine models were divided into a robot- and navigation-assisted groups according to the left and right sides of the pedicle. The C-arm transmits image data simultaneously to the robot and navigates using only one scan. After screw placement, the accuracy of the two techniques were compared using \u201cangular deviation\u201d and \u201cGertzbein and Robbins scale\u201d in different segments (C1\u20137, T1\u20134, T5\u20138, T9\u201312, and L1\u2013S1). In addition, operation times were compared between robot- and navigation-assisted groups.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Robots and navigation systems can simultaneously assist in screw placement. The robot-assisted group had significantly less angular deviation than the navigation-assisted group from C1 to S1 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). At the C1\u20137 and T1\u20134 segments, the robot-assisted group had a higher rate of acceptable screws than the robot-assisted group. However, at the T5\u20138, T9\u201312, and L1\u2013S1 segments, no significant difference was found in the incidence of acceptable screws between the two groups. Moreover, robot-assisted screw placement required less operative time than navigation (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The robot is more accurate and efficient than navigation in aiding screw placement.
