    The study compared three fixation strategies for complex acetabular fractures: 3D-printed guide-assisted cannulated screw plus plate, conventional cannulated screw plus plate, and plate-only.

  • 2

    Finite element analysis indicated that combined cannulated screw-plate fixation offered better fracture-line displacement control, especially under sitting conditions.

  • 3

    The 3D-printed guide group had significantly shorter operative time, lower intraoperative blood loss, and shorter incision length compared to the plate-only group.

  • 4

    Both the 3D-printed guide and conventional screw plus plate groups had lower total hospitalization costs compared to the plate-only group.

  • 5

    No significant differences were found in complication risk, 3-month hip function, or hospital length of stay among the different fixation strategies.
