Summary

This summary is machine-generated.

Patient-specific osteotomy templates, created using 3D printing, significantly improve the precision of pelvic tumor surgery. This technology reduces intraoperative bleeding and enhances accuracy in tumor resection compared to conventional methods.

Area Of Science

  • Oncology
  • Surgical Technology
  • Medical Imaging

Background

  • Pelvic tumor treatment presents significant surgical challenges.
  • Precise tumor resection is crucial for patient outcomes.
  • Conventional surgical techniques may lack the necessary accuracy for complex pelvic tumors.

Purpose Of The Study

  • To evaluate the accuracy of patient-specific osteotomy templates in pelvic tumor resection.
  • To compare surgical outcomes between using and not using custom osteotomy templates.
  • To assess the impact of 3D-printed templates on surgical precision.

Main Methods

  • A cohort of 27 patients with pelvic tumors underwent surgery between April 2014 and August 2023.
  • 3D preoperative imaging models were created using CT and MRI fusion images.
  • Patient-specific osteotomy templates were utilized in one group for guided resection, while a control group used conventional methods.

Main Results

  • The use of osteotomy templates significantly reduced intraoperative bleeding (median 2350 ml vs. 4500 ml, p=0.016).
  • Templates led to a significant decrease in angular deviation (5.02° vs. 7.17°, p=0.044).
  • A significant reduction in mean distance deviation was observed (4.90 mm vs. 7.21 mm, p=0.038).

Conclusions

  • 3D-printed patient-specific osteotomy templates offer high accuracy.
  • These templates can be reliably customized using preoperative imaging.
  • The technology enhances the precision of pelvic tumor surgery.
