Area of Science:

  • Orthopaedic surgery
  • Medical imaging
  • 3D printing technology

Background:

  • Three-dimensional (3D) printing is increasingly used in clinical settings, particularly for orthopaedic surgical planning in trauma cases.
  • Accurate 3D models of fractures are crucial for guiding interventions and designing patient-specific implants.
  • A need exists for uncomplicated, inexpensive, and rapid 3D modeling workflows for complex fractures.

Purpose of the Study:

  • To develop and evaluate a novel, simple, open-source, and rapid 3D bone modeling workflow using Drishti software.
  • To compare the efficacy, data storage, and processing time of Drishti against the 3D Slicer platform.
  • To demonstrate the compatibility of Drishti-generated 3D models for customized implant design.

Main Methods:

  • Utilized patient DICOM datasets (n=13) for 3D model generation.
  • Employed Drishti software for bone surface isolation from surrounding tissues.
  • Compared Drishti's performance in terms of data size and processing time against 3D Slicer.
  • Integrated a pelvic fracture case into a customized implant design workflow.

Main Results:

  • Drishti generated 3D models with 27% smaller data sizes and 12% smaller processing files than 3D Slicer (P < 0.05).
  • Drishti was 39% faster in viewing 3D bone models and 38% faster in data export compared to 3D Slicer (P < 0.05).
  • Both software platforms demonstrated compatibility with third-party implant design programs.

Conclusions:

  • Drishti is highly suitable for urgent trauma cases requiring fast, efficient 3D bone reconstruction with minimal hardware.
  • 3D Slicer excels in quantitative preoperative planning and multilayer segmentation.
  • Both Drishti and 3D Slicer facilitate the creation of customized implants for surgical training and planning.
