Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Pre-operative planning is crucial for patient-specific orthopedic surgery.
  • Current osteotomy planning relies on 2D radiographs, requiring surgeons to mentally visualize 3D bone deformities.
  • Advanced 3D imaging like CT scans are not widely accessible for routine orthopedic procedures.

Purpose of the Study:

  • To present a novel technique for 3D bone reconstruction using bi-planar 2D radiographic images.
  • To provide a method for improving osteotomy surgical diagnostics and planning.
  • To enable the creation of patient-specific 3D bone models from conventional X-rays.

Main Methods:

  • Utilizing a generic 3D bone model to capture anatomical topology.
  • Performing 2D non-rigid registration between projected model contours and X-ray image edges.
  • Employing free-form deformation for customizing the 3D bone shape.

Main Results:

  • A novel framework for 3D bone reconstruction from bi-planar 2D radiographs was developed.
  • The technique allows for patient-specific customization of 3D bone models.
  • The method facilitates improved visualization for osteotomy planning.

Conclusions:

  • The presented 3D bone reconstruction technique offers a viable alternative to advanced imaging for osteotomy planning.
  • This approach can enhance pre-operative planning by providing patient-specific 3D models from readily available 2D images.
  • The method has the potential to improve surgical outcomes in osteotomy procedures.
