Area of Science:

  • Medical imaging
  • Computer-assisted surgery
  • Orthopedic surgery

Context:

  • Trauma surgery often involves complex long bone fracture treatment.
  • Accurate 3D visualization is crucial for surgical precision.
  • Minimizing radiation exposure for patients and staff is a key concern.

Purpose:

  • To present an original method for 3D modeling of long objects from two X-ray views.
  • To demonstrate two navigation applications in trauma surgery for long bone fracture treatment.
  • To provide surgeons with real-time 3D guidance for improved surgical outcomes.

Summary:

  • A novel 3D modeling technique utilizes the intersection of projection cones from two X-ray views to create an approximated 3D model of long objects.
  • The method is applied to diaphyseal fracture reduction using external fixation, providing real-time 3D visualization of bone fragments and their alignment.

  • A second application involves distal locking of intra-medullary nails, where a 3D model guides the surgeon during the targeting process using tracked instruments.

    • Impact:

    • Enables precise, real-time 3D guidance for surgeons during complex orthopedic procedures.
    • Facilitates accurate control of fracture reduction and distal targeting in trauma surgery.
    • Significantly reduces radiation exposure for patients and the surgical team through efficient imaging techniques.
