Clinical Report: Efficacy and Biomechanical Assessment of 3D-Printed Guide Plate

Overview

This study evaluates the efficacy of 3D-printed guide plate-assisted cannulated screw fixation compared to traditional methods for complex acetabular fractures. Findings indicate improved perioperative efficiency and biomechanical stability without compromising safety or functional recovery.

Background

Pelvic and acetabular fractures are severe injuries often resulting from high-energy trauma, leading to significant morbidity and mortality. The complexity of these fractures necessitates effective fixation strategies that balance stability and minimally invasive techniques. Recent advances in 3D printing technology offer potential improvements in surgical precision and outcomes.

Data Highlights

GroupOperative Time (min)Intraoperative Blood Loss (mL)Incision Length (cm)Total Hospitalization Costs (RMB)
3D-Printed Guide−56.15−575.48−7.94−39,944.29
Conventional Screw + Plate−68.46N/AN/A−32,527.55
Plate-OnlyN/AN/AN/AN/A

Key Findings

  • Combined cannulated screw–plate fixation offers better fracture-line displacement control, especially under sitting conditions.
  • The 3D-printed guide group had significantly shorter operative times compared to both the plate-only and conventional screw plus plate groups.
  • Intraoperative blood loss was significantly lower in the 3D-printed guide group compared to the plate-only group.
  • Both the 3D-printed guide and conventional screw plus plate groups had lower total hospitalization costs than the plate-only group.
  • No significant differences were observed in complication risk, 3-month hip function, or hospital length of stay across groups.

Clinical Implications

The use of 3D-printed guide plates in acetabular fracture fixation may enhance surgical efficiency and reduce intraoperative complications. These findings support the integration of advanced technologies in orthopedic surgery to improve patient outcomes.

Conclusion

The study demonstrates that 3D-printed guide plate-assisted fixation is a viable option for complex acetabular fractures, providing both biomechanical stability and improved perioperative efficiency.
