Objective:

To compare the clinical efficacy of E3D-assisted design with a personalized 3D-printed guiding system against traditional fluoroscopic percutaneous screw fixation for pelvic fractures.

Key Findings:

• Shorter operation time in the experimental group (53.05 ± 19.04 min) compared to control (81.05 ± 24.68 min, p < 0.001).
• Higher screw placement accuracy in the experimental group for various anatomical landmarks.
• No significant difference in fracture reduction quality between the two groups.

Interpretation:

E3D-assisted design with personalized 3D-printed guides improves surgical efficiency and accuracy in pelvic fracture management, enhancing safety and reducing the learning curve for clinicians.

Limitations:

• Study limited to a specific timeframe and patient population.
• Retrospective design may introduce bias.

Conclusion:

E3D-assisted design combined with personalized 3D-printed guides offers significant advantages in minimally invasive pelvic fracture treatment, including reduced surgery time and improved screw accuracy.
