Trigger Finger Release: A Technique for Ensuring Safe and Adequate Release.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Anatomy

Background:

• Trigger finger release is common but can lead to complications like relapse or bowstringing due to improper technique.
• Difficulty in visualizing the A1 and A2 pulleys and their transition increases the risk of surgical errors.

Purpose of the Study:

• To describe a safe, effective, and reproducible surgical technique for A1 pulley release in trigger finger.
• To improve visualization and reduce complications associated with trigger finger release surgery.

Main Methods:

• The technique involves sharply incising the A1 pulley proximally, leveraging its anatomical contiguity with the volar plate.
• Adequacy of release is assessed by visualizing the synovial side of the A1 pulley where it meets the volar plate.

Main Results:

• This method enhances visualization of the A1 pulley's borders, particularly on the synovial side.
• Ensures complete A1 pulley release, preventing recurrence of triggering and avoiding A2 pulley release complications.

Conclusions:

• The described technique provides a clear and reproducible method for A1 pulley release.
• It minimizes risks of incomplete release and associated complications, leading to better patient outcomes.
