Automated methods enhance lower extremity surgery planning for osteotomies and osteosynthesis. This approach uses imaging and tracking for precise bone correction, validated in lab and ex vivo tests.

Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Robotics in Medicine

Background:

  • Correction osteotomies and osteosynthesis are critical orthopedic procedures.
  • Accurate planning is essential for optimal patient outcomes.
  • Current methods can be time-consuming and rely heavily on surgeon experience.

Purpose of the Study:

  • To present automated methods for planning correction osteotomies and osteosynthesis.
  • To improve the precision and efficiency of lower extremity fracture repair.
  • To integrate intraoperative imaging and navigation for surgical guidance.

Main Methods:

  • Utilizing intraoperative calibrated X-ray images and optical tracking systems.
  • Employing surgeon input combined with optimization algorithms for surgical planning.
