An investigation to the clinical application of personalized 3D printed guides combined with preoperative virtual iliosacral screws for the management of posterior pelvic ring injury.

Although the difference in screw misposition rates between the GP group and the CS group in this study did not reach statistical significance, the numerical downward trend in the misposition rate of the GP group (5.56% in the GP group vs. 16.67% in the CS group) still suggests its potential value in improving the accuracy of screw placement.
