Summary
This study introduces an augmented reality (AR) navigation system for sacroiliac screw insertion. The system proved feasible and accurate in cadaveric tests, showing potential for improved surgical guidance.
Area of Science:
- Medical Imaging and Navigation
- Surgical Technology
- Orthopedic Surgery
Background:
- Augmented reality (AR) enhances surgical procedures by overlaying virtual information onto the real-world view.
- Percutaneous sacroiliac screw insertion is a critical orthopedic procedure requiring high precision.
Purpose of the Study:
- To present a novel augmented reality (AR)-based navigation system for sacroiliac screw insertion.
- To evaluate the feasibility and accuracy of this AR navigation system in cadaveric experiments.
Main Methods:
- Six cadavers underwent CT scanning for 3D model creation of the pelvis and vessels.
- An AR system displayed the planned screw trajectory within the surgeon's field of view via a head-mounted display.
- Sacroiliac screws were inserted under AR guidance, followed by CT assessment of accuracy.
Main Results:
- All 12 inserted screws were accurately placed without perforation.
- Mean deviation at the entry point was 2.7 mm, and at the screw tip was 3.7 mm.
- Mean angular deviation between planned and inserted trajectories was 2.9°.
Conclusions:
- The AR-based navigation system provides an intuitive and accurate method for guiding sacroiliac screw placement.
- This system demonstrates feasibility and potential as a valuable tool for percutaneous sacroiliac screw insertion in clinical settings.
