Summary

Endoscopic carpal tunnel release offers faster recovery and less pain than open surgery. It appears cost-effective, but surgeon training is crucial to minimize median nerve injury risks.

Area of Science:

  • Orthopedic Surgery
  • Health Economics

Background:

  • Carpal tunnel syndrome (CTS) has significant economic and social impact.
  • Endoscopic carpal tunnel release (ECTR) is debated due to potential higher complication rates versus faster recovery.
  • Open carpal tunnel release (OCTR) is the traditional standard.

Purpose of the Study:

  • To conduct a cost-effectiveness analysis comparing ECTR and OCTR.
  • To evaluate procedures based on quality-adjusted life-years (QALYs) from a societal perspective.

Main Methods:

  • A decision analytic model and decision tree were utilized.
  • Probabilities of outcomes were sourced from randomized controlled trials.
  • Cost data derived from Medicare Relative Value Units; QALYs from healthcare provider questionnaires.

Main Results:

  • ECTR had an incremental cost difference of $46 compared to OCTR.
  • Cost-effectiveness ratios ranged from $195/QALY to $693/QALY across age groups.
  • ECTR is cost-effective compared to other medical interventions like breast cancer screening.

Conclusions:

  • ECTR appears cost-effective, but its ratio is sensitive to median nerve injury rates.
  • Surgeon training is essential to reduce complications and ensure cost-effectiveness.
  • Further research needed to clarify nerve injury incidence for both techniques in community settings.
