Surgical Treatment for Trigger Thumb Using a Radial Approach

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Anatomy

Background:

• Thumb flexor pulley system anatomy varies from fingers.
• Trigger thumb release can be complicated by hand positioning.
• Radial digital nerve injuries are a risk with current A1 pulley release techniques.

Purpose of the Study:

• To introduce a novel radial approach for trigger thumb surgical release.
• To mitigate risks of radial digital nerve injury and flexor pollicis longus bowstringing.
• To improve surgical hand positioning and reduce postoperative pain for enhanced recovery.

Main Methods:

• Utilizing a transverse incision for a radial approach to A1 pulley release.
• Focusing on anatomical considerations specific to the thumb.
• Implementing techniques to prevent iatrogenic nerve damage and tendon displacement.

Main Results:

• The radial approach facilitates a more ergonomic surgical hand position.
• This technique is designed to avoid injury to the radial digital nerve.
• The approach aims to prevent bowstringing of the flexor pollicis longus tendon.
• Reduced postoperative pain is anticipated, aiding functional recovery.

Conclusions:

• The radial approach presents a potentially safer alternative for trigger thumb release.
• This method addresses specific anatomical challenges of the thumb pulley system.
• Further studies are warranted to validate long-term outcomes and efficacy.
