Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Biomechanical Engineering

Background:

  • Accurate pre-operative planning is crucial for successful osteotomy procedures.
  • Current methods for hip joint assessment may lack the precision required for complex surgeries.
  • Advancements in medical imaging and computational modeling offer potential for improved surgical planning.

Purpose of the Study:

  • To develop a method for creating a 3D mathematical surface model of the hip joint from CT images.
  • To assess the feasibility of using this model for planning computer-aided osteotomies.
  • To explore future integration with MRI for enhanced cartilage surface reconstruction.

Main Methods:

  • Image preprocessing of planar computed tomography (CT) images of the hip joint.

    • Main Results:

    • Diagnostic contours of the hip joint were successfully extracted from CT images.
    • A mathematical surface model of the hip joint was derived from the extracted contour data.
    • The derived model facilitates the simulation of osteotomies.

    Conclusions:

    • The developed image-analysis process enables the creation of a 3D hip joint model from CT scans.
    • This model supports the accurate planning of computer-aided osteotomies.
    • Future integration with MRI for cartilage reconstruction promises even higher surgical accuracy.
