Summary
This study shows surgeons can accurately evaluate hand anatomy and use it for ultrasound-guided carpal tunnel release. This minimally invasive technique completely released the transverse carpal ligament in cadavers without causing injury.
Area of Science:
- Orthopedics
- Surgical Innovation
- Anatomy
Background:
- Minimally invasive surgery is now standard for many procedures.
- Carpal tunnel syndrome is a common condition requiring surgical intervention.
Purpose of the Study:
- To assess surgeons' ability to perform accurate hand and forearm anatomic evaluations.
- To evaluate a novel sonographically guided, percutaneous carpal tunnel release technique using a single-portal endoscope without direct visualization.
Main Methods:
- Anatomic evaluation of the hand and forearm in 10 cadavers.
- Sonographically guided, percutaneous carpal tunnel release in 6 cadavers using a single-portal endoscope.
- Open dissection to confirm ligament transection and assess for surrounding structure injury.
Main Results:
- Surgeons demonstrated accurate anatomic evaluation capabilities.
- Complete transection of the transverse carpal ligament was achieved in all 6 cadavers.
- No injuries to surrounding structures were observed in any of the cadavers.
Conclusions:
- The demonstrated technique allows for accurate sonographically guided, percutaneous carpal tunnel release.
- This novel approach may offer a less invasive, office-based treatment option for carpal tunnel syndrome.
- Further investigation could lead to expedited patient recovery.
