Area of Science:

  • Orthopedic Surgery
  • Medical Imaging Analysis
  • Biomedical Engineering

Background:

  • Preoperative planning is crucial for successful hip arthroplasty.
  • Existing computed tomography (CT) software for surgical planning lacks comparative studies, especially for osteoarthritic or osteoporotic hip conditions.
  • Accurate 3D modeling of pathological femoral heads is essential for patient-specific surgical approaches.

Purpose of the Study:

  • To compare three software tools (Syngo.via Frontier, Materialise Mimics, and 3D Slicer) for 3D reconstruction of pathological femoral heads.
  • To evaluate these tools based on geometric accuracy, dimensional precision, and usability.
  • To identify the optimal software for preoperative planning in hip arthroplasty involving complex pathologies.

Main Methods:

  • Reconstruction of 3D models of pathological femoral heads from in vivo CT scans using Syngo.via Frontier, Materialise Mimics, and 3D Slicer.
  • Comparison of reconstructed 3D models against in vitro laser scan data of bony specimens.
  • Evaluation of software performance based on geometric, dimensional accuracy, and user-friendliness.

Main Results:

  • Materialise Mimics and 3D Slicer demonstrated superior dimensional and geometric accuracy in 3D reconstructions.
  • Syngo.via Frontier was identified as the most user-friendly software for clinical settings.
  • The study provides quantitative data on the performance of different 3D modeling tools for hip surgery planning.

Conclusions:

  • Materialise Mimics and 3D Slicer are recommended for achieving high-fidelity 3D reconstructions of pathological femoral heads in hip arthroplasty planning.
  • Syngo.via Frontier offers a practical, user-friendly option for rapid prototyping in a hospital environment.
  • Further research could explore integration of these tools into surgical workflows to enhance patient outcomes.
