Endoscopic carpal tunnel release offers faster initial pain relief and functional improvement within two weeks compared to open surgery. Long-term outcomes at one year are similar for both carpal tunnel surgery techniques.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Minimally Invasive Procedures

Background:

  • Carpal tunnel syndrome (CTS) is a common condition causing hand numbness and pain.
  • Surgical intervention is often required for severe or persistent CTS.
  • Traditional open carpal tunnel release has been the standard treatment.

Purpose of the Study:

  • To compare the short- and long-term functional and clinical outcomes of endoscopic carpal tunnel release versus conventional open carpal tunnel release.
  • To evaluate the efficacy of each surgical technique in improving CTS symptoms and patient functionality.

Main Methods:

  • A comparative study involving 72 outpatients diagnosed with carpal tunnel syndrome.
  • Patients were randomized to either the endoscopic carpal tunnel release (37 patients) or the open carpal tunnel release (35 patients) group.

Ultrasound-Guided Needle Release Combined with Corticosteroid Injection for the Treatment of Supinator Syndrome

  • Outcomes including symptom improvement, severity, functionality, grip strength, and complications were assessed at multiple postoperative intervals (2 days, 1 week, 2 weeks, and 1 year).

    • Main Results:

    • Both endoscopic and open carpal tunnel release showed comparable clinical outcomes at one year postoperatively.
    • The endoscopic group demonstrated significantly greater improvement in grip strength at one year.
    • Faster relief of pain and improved functional status were observed in the endoscopic group within the first two weeks post-surgery.

    Conclusions:

    • Endoscopic carpal tunnel release provides a quicker recovery during the initial two weeks, with faster pain relief and functional gains.
    • Paresthesia and numbness resolved similarly in both groups.
    • At one year, both endoscopic and open carpal tunnel release techniques appear to be equally effective for treating carpal tunnel syndrome.
