Summary
The thread trigger finger release (TTFR) technique, adapted from carpal tunnel surgery, proved safe and effective in cadaveric studies. This innovative approach achieved complete A1 pulley release without damaging surrounding structures, paving the way for clinical trials.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Minimally Invasive Procedures
Background:
- The thread transecting technique, successful for carpal tunnel release, was investigated for trigger finger release (TTFR).
- Trigger finger release often involves division of the first annular (A1) pulley.
Purpose of the Study:
- To assess the operational feasibility of TTFR on cadavers.
- To determine the safe division limits of the A1 pulley for complete trigger finger release.
- To minimize iatrogenic injuries during TTFR.
Main Methods:
- TTFR procedure performed on 14 fingers and 4 thumbs from 4 unembalmed cadaveric hands.
- Post-procedure dissection and visual assessment of all treated digits and thumbs.
Main Results:
- Complete release of the A1 pulley was achieved in all cases.
- No injuries to the neurovascular bundle, flexor tendon, or A2 pulley were observed.
- The technique demonstrated high safety and efficacy in the cadaveric model.
Conclusions:
- Cadaveric study confirms TTFR is a safe and effective technique.
- Further clinical studies are warranted to validate these findings in human patients.
