Table 2.
Pedicle Screw Accuracy Scores shows the postoperative pedicle screw accuracy scores. The MR group achieved significantly higher accuracy (Grade A and B) compared to the control group (CG group) (P = 0.04). There were also significant differences in entry point, angular, and depth deviations between the groups
