This study introduces a novel software system for virtual hip surgery planning. It enables precise simulation of endoprosthetic reconstruction for bone tumor patients, aiding custom prosthesis design.

Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Bone tumors necessitate complex hip joint reconstructions.
  • Current methods for endoprosthetic reconstruction can be challenging.
  • Accurate preoperative planning is crucial for successful outcomes.

Purpose of the Study:

  • To present a new software system for virtual preoperative planning and simulation of hip operations.
  • To support the individual design of anatomically adaptable, modular prostheses for hemipelvic replacement.
  • To enhance surgical precision and patient outcomes in complex hip reconstructions.

Main Methods:

  • Generation of 3D patient hip models from CT data.
  • Virtual simulation of endoprosthetic reconstruction with custom prosthesis design.

  • Utilizing stereoscopic visualization and 3D input devices for interactive planning.
  • Employing advanced visualization techniques (texture mapping, color coding, transparency).

    • Main Results:

    • The system facilitates detailed simulation of hip operations, including hemipelvic replacement.
    • Surgeons can define the precise position and shape of custom-made endoprostheses.
    • Advanced visualization aids in determining optimal prosthesis placement and form.
    • The software supports patient information and educational purposes.

    Conclusions:

    • The developed software system offers a valuable tool for virtual preoperative planning of hip operations.
    • It enhances the design and simulation process for custom endoprostheses in bone tumor patients.
    • The system has potential applications in improving surgical planning, patient education, and surgical training.
