Endoscopic release of the carpal tunnel: a technical note

Area of Science:

• Orthopedic Surgery
• Minimally Invasive Procedures
• Nerve Entrapment Syndromes

Background:

• The Agee technique is a widely used method for endoscopic carpal tunnel release.
• Carpal tunnel syndrome affects numerous individuals, necessitating effective surgical interventions.
• Standard techniques carry risks, including potential nerve injury.

Purpose of the Study:

• To describe a modification of the standard Agee technique for endoscopic carpal tunnel release.
• To introduce the use of urethral dilators for path preparation.
• To evaluate the potential benefits of this modified approach in improving surgical outcomes and safety.

Main Methods:

• The modification involves using urethral dilators to gradually dilate the pathway for the endoscopic blade assembly.
• This allows for a controlled and graded dilatation of the carpal tunnel.
• The technique aims to create a more uniform track for the instruments.

Main Results:

• The modified technique permits graded dilatation, potentially creating a track of more uniform width.
• It offers more accurate intraoperative assessment of carpal tunnel tightness.
• The enhanced visualization and control may lead to a reduced risk of iatrogenic nerve injury.

Conclusions:

• This modified Agee technique offers a potentially safer and more precise method for endoscopic carpal tunnel release.
• The use of urethral dilators provides valuable information on tunnel tightness and facilitates instrument passage.
• Further studies are warranted to confirm the long-term efficacy and safety benefits of this modification.
