Summary
A new thread, Smartwire-01, proved as effective as existing options for thread carpal tunnel release (TCTR). This innovative thread offers a better user experience for carpal tunnel surgery.
Area of Science:
- Orthopedic Surgery
- Surgical Innovation
- Anatomy
Background:
- Carpal tunnel release (TCTR) is a common surgical procedure.
- Existing thread-based methods have varying degrees of efficacy and user experience.
Purpose of the Study:
- To evaluate the modified thread carpal tunnel release (TCTR) technique.
- To compare the performance of a novel thread (Smartwire-01) against a commercial thread (Loop&ShearTM).
Main Methods:
- Utilized 17 cadaveric wrists for modified TCTR practice by two experts.
- Compared Loop&ShearTM (5 wrists) with Smartwire-01 (12 wrists).
- Assessed gross and microanatomy by a blinded anatomist.
Main Results:
- Both threads effectively transected the transverse carpal ligament (TCL).
- No significant anatomical or histological differences were observed between the threads.
- Practitioners reported enhanced ease of use with the Smartwire-01.
Conclusions:
- Modified TCTR using Smartwire-01 is a viable alternative to Loop&ShearTM.
- Smartwire-01 demonstrates comparable efficacy with improved user experience in carpal tunnel release.
