Endoscopic carpal tunnel release often results in incomplete ligament transection. Surgeons require extensive cadaver practice to master this technically demanding procedure and minimize errors.

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Surgical Techniques

Background:

  • Carpal tunnel syndrome is a common condition.
  • Endoscopic carpal tunnel release is a minimally invasive surgical option.
  • Ensuring complete ligament transection is crucial for surgical success.

Purpose of the Study:

  • To evaluate the technical accuracy of endoscopic carpal tunnel release.
  • To identify common errors and assess the completeness of transverse carpal ligament release.

Main Methods:

  • Five surgeons performed endoscopic carpal tunnel release on 24 fresh cadaver wrists.
  • Ligament transection completeness was quantitatively assessed.
  • Types of incomplete release and other technical errors were documented.

Main Results:

  • 50% of transverse carpal ligaments were incompletely released, averaging 31%.
  • Incomplete release occurred in the central/superficial portion (6), distal ligament (5), and Guyon's canal (1).
  • Technical errors were noted in 9 of 24 specimens; no nerve lacerations occurred.

Conclusions:

  • Endoscopic carpal tunnel release is technically demanding and frequently results in incomplete ligament release.
  • Thorough training and cadaver practice are recommended before clinical application.
  • Improved techniques and training may enhance procedural outcomes.
