This study shows endoscopic carpal tunnel release is effective for symptom relief and has a low complication rate. Patients experienced minimal palmar pain and an early return to work after the procedure.

Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Hand Surgery

Background:

  • Carpal tunnel syndrome (CTS) is a common condition causing hand pain and numbness.
  • Traditional open carpal tunnel release can be effective but may involve longer recovery times.
  • Minimally invasive techniques are being explored to improve patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of a novel endoscopic carpal tunnel release technique.
  • To assess symptom relief, return to work, and complication rates associated with this new method.

Main Methods:

  • A prospective cohort study was conducted in a university hand surgery practice.
  • Ninety-five adult patients (108 procedures) underwent outpatient endoscopic carpal tunnel release using the two-portal Chow technique.

  • Outcomes measured included symptom relief, return to work, medication use, and complications.

    • Main Results:

    • The endoscopic technique demonstrated high efficacy, with most patients experiencing symptom relief.
    • A low complication rate of 3.8% was observed, with no nerve or vascular injuries.
    • Patients returned to work significantly faster, averaging 19.5 days for non-Workers' Compensation cases.

    Conclusions:

    • Endoscopic carpal tunnel release using the Chow technique is an effective and safe procedure.
    • The technique leads to significant symptom improvement and a rapid return to work.
    • Minimal palmar pain and a low complication profile make this an attractive option for carpal tunnel syndrome treatment.
