Area of Science:

  • Orthopedic Surgery
  • Surgical Navigation Technology
  • Medical Device Innovation

Background:

  • Personalized surgical guides are common in orthopedics but lack intraoperative re-planning capabilities.
  • Current navigation systems often face challenges with small anatomical structures or limited exposure sites.

Purpose of the Study:

  • To present a novel tracked guide system for orthopedic surgery.
  • To enable intraoperative re-planning and improve surgical navigation accuracy.
  • To evaluate the system's performance in complex anatomical scenarios.

Main Methods:

  • Developed a tracked guide system utilizing physical registration for coordinate frame transformation.
  • Integrated the guide with a surgical navigation platform.
  • Conducted a study on seven femoral models derived from clinical CT scans for hip resurfacing.

Main Results:

  • Achieved a guide characterizationフレ (frame registration error) of 0.4°±0.2°.
  • Obtained a drill-path angular TRE (target registration error) of 0.9°±0.4°.
  • Demonstrated a positional TRE of 1.2mm±0.4mm, comparable to optical tracking accuracy.

Conclusions:

  • The novel tracked guide offers a viable solution for intraoperative re-planning in orthopedic surgery.
  • The system's accuracy is suitable for procedures with small surgical exposures or challenging anatomical regions.
  • This technology has the potential to enhance precision in minimally invasive orthopedic interventions.
