Summary

A novel one-portal endoscopic carpal tunnel release (ECTR) using a glass tube shows promising results. This technique effectively releases the flexor retinaculum with minimal complications in most patients.

Area of Science:

  • Orthopedics
  • Minimally Invasive Surgery
  • Hand Surgery

Background:

  • Carpal tunnel syndrome (CTS) is a common condition causing hand pain and numbness.
  • Traditional surgical treatments for CTS can have drawbacks like scarring and nerve injury.
  • Endoscopic carpal tunnel release (ECTR) offers a less invasive alternative.

Purpose of the Study:

  • To introduce and evaluate a new one-portal endoscopic carpal tunnel release (ECTR) technique.
  • To assess the safety and efficacy of this novel technique in cadaveric and clinical settings.

Main Methods:

  • A custom-made glass tube with a groove was used for a one-portal endoscopic approach.
  • The flexor retinaculum was released under direct endoscopic visualization using a meniscus knife.

  • The technique was tested on ten cadaver hands and applied to 123 patient hands.

    • Main Results:

    • Complete release of the flexor retinaculum was achieved in all cadaveric specimens without neurovascular injury.
    • The clinical procedure was largely uneventful, with minor complications in a small percentage of patients.
    • Complications included digital nerve neuropraxia, median nerve motor branch laceration, infection, and device-related issues.

    Conclusions:

    • The one-portal ECTR technique with a glass tube is a viable option for carpal tunnel release.
    • Advantages include reduced scar tenderness, lower risk of injury to critical structures, and direct visualization of the carpal tunnel.
    • Careful technique and early recognition of complications are essential for optimal outcomes.
