Summary
This study shows that a new electromagnetic navigation system (ENS) is accurate and safe for transclavicular-transcoracoid drilling. The radiation-free method achieved precise tunnel placement without complications in cadaveric procedures.
Area of Science:
- Orthopedic surgery
- Medical device technology
- Surgical navigation
Background:
- Transclavicular-transcoracoid drilling is crucial for certain orthopedic procedures.
- Traditional methods may involve radiation exposure.
- Need for accurate and safe navigation techniques.
Purpose of the Study:
- To develop and evaluate a novel, radiation-free electromagnetic navigation system (ENS) for transclavicular-transcoracoid drilling.
- Assess the feasibility and accuracy of this ENS-based method.
Main Methods:
- Performed 16 arthroscopically assisted drilling procedures using ENS on 8 human cadavers.
- Implanted TightRope devices post-drilling.
- Evaluated tunnel placement accuracy using post-operative fluoroscopy and CT scans.
Main Results:
- Achieved successful tunnel placement in all 16 procedures.
- 93.8% of tunnels had optimal coracoid exit point placement.
- No intraoperative drill misguidance, cortical breaches, fractures, or complications occurred.
Conclusions:
- The ENS-based drilling procedure demonstrated high targeting accuracy.
- The method is radiation-free, user-friendly, and complication-free.
- This technique offers a safe and effective alternative for transclavicular-transcoracoid drilling.
