Hypothesis
Can a new technique for marking the distal extent of the A1 pulley during trigger finger release prevent injury to the A2 pulley?
Conclusion
The new technique ensures complete release of the A1 pulley while preserving the A2 pulley and adds no morbidity.
Supporting Evidence
- All specimens achieved complete release of the A1 pulley.
- The A2 pulley was preserved in all cases.
- No digital nerve or artery injuries were noted.
Takeaway
Doctors found a safe way to fix a finger problem without hurting other important parts of the hand.
Methodology
Nine fresh cadaveric hands were dissected using loupe magnification to mark the distal extent of the A1 pulley.
Potential Biases
None reported.
Limitations
The study was conducted on cadaveric hands, which may not fully represent live anatomy.
Participant Demographics
Fresh cadaveric hands.
