Summary

A new single portal endoscopic carpal tunnel release kit showed improved scar tenderness and grip strength compared to open surgery. While effective, this endoscopic carpal tunnel technique carries a risk of neurovascular injury.

Area of Science:

  • Orthopedics
  • Minimally Invasive Surgery

Background:

  • Carpal tunnel syndrome is a common condition requiring surgical intervention.
  • Traditional open carpal tunnel release can result in significant scarring and prolonged recovery.
  • Endoscopic techniques aim to minimize invasiveness and improve patient outcomes.

Purpose of the Study:

  • To evaluate the safety and efficacy of a novel single portal endoscopic carpal tunnel release kit.
  • To compare outcomes of the new endoscopic technique with conventional open carpal tunnel release.

Main Methods:

  • A prospective clinical study comparing 64 patients undergoing single portal endoscopic release (group 1) with 62 patients undergoing open release (group 2).
  • Patients were followed for 24 weeks postoperatively, assessing complications, scar tenderness, functional status, grip strength, and pinch strength.

  • Statistical analysis was performed to compare outcomes between the two groups.

    • Main Results:

    • The endoscopic group (group 1) experienced significantly less scar tenderness at 1, 3, and 24 weeks postoperatively compared to the open group (group 2).
    • Grip and pinch strength were significantly higher in the endoscopic group at several postoperative time points.
    • Functional status was better in the endoscopic group at 1 week but not significantly different later.
    • One serious intraoperative complication (superficial palmar arch injury) occurred in the endoscopic group; none in the open group.

    Conclusions:

    • The single portal endoscopic carpal tunnel release kit is a reliable tool for treating carpal tunnel syndrome.
    • This endoscopic approach offers benefits in terms of reduced scar tenderness and improved early strength recovery.
    • Potential risks of neurovascular injury exist with endoscopic carpal tunnel release techniques.
