Complete carpal tunnel decompression requires releasing both the transverse carpal ligament and transverse fibers. This endoscopic surgical model demonstrates essential steps for effective pressure reduction in the carpal canal.

Area of Science:

  • Orthopedic Surgery
  • Minimally Invasive Procedures
  • Anatomy

Background:

  • Carpal tunnel syndrome is a common condition causing hand pain and numbness.
  • Endoscopic carpal tunnel release is a widely used surgical technique.
  • Adequate decompression of the carpal canal is crucial for surgical success.

Purpose of the Study:

  • To model and evaluate the effectiveness of different surgical steps in endoscopic carpal tunnel decompression.
  • To determine the essential structures that must be released for complete carpal canal decompression.
  • To analyze the impact of releasing transverse fibers in addition to the transverse carpal ligament.

Main Methods:

  • Development of a clinical model for endoscopic carpal canal decompression.
  • Stepwise release of anatomical structures: transverse carpal ligament, transverse fibers, and forearm fascia.

  • Continuous measurement of carpal canal pressure using the infusion technique.
  • Endoscopic visualization at each surgical step.
  • Statistical analysis of pressure data using the Wilcoxon matched pairs signed-rank test.

    • Main Results:

    • Carpal canal pressure significantly decreased when both the transverse carpal ligament and transverse fibers were divided.
    • Releasing only the transverse carpal ligament resulted in less pressure reduction compared to combined release.
    • Endoscopic observation confirmed anatomical changes during the stepwise decompression.

    Conclusions:

    • Complete decompression of the carpal canal in endoscopic surgery necessitates the release of both the transverse carpal ligament and the transverse fibers.
    • The transverse fibers, including the deep layer of the midpalmar fascia or distal flexor retinaculum, play a critical role in carpal canal pressure.
    • This study provides evidence-based recommendations for optimizing endoscopic carpal tunnel release techniques.
