Is this trial a fit for you?

Likely a good fit

Adults with electrophysiologically confirmed carpal tunnel syndrome who have exhausted conservative treatments and are planned for surgical release.

Probably not a fit

Patients with prior surgery at the same site, non-CTS nerve conditions, or contraindications to either procedure may not benefit.

What this trial studies

This multicenter, prospective observational study follows patients undergoing either open surgical carpal tunnel release or ultrasound-guided release. Centers assign treatment based on their standard practice rather than randomization, with 200 participants split evenly between the two cohorts. Participants are assessed before surgery and at 2 weeks, 6 weeks, 3 months, and 12 months after the procedure to evaluate functional recovery, symptoms, pain, return to work, satisfaction, and complications. The analysis focuses on clinical outcomes, patient-reported outcomes, and socioeconomic impact. The aim is to understand whether the less invasive ultrasound-guided approach offers advantages over the traditional open procedure in real-world settings.

Why it matters

Potential benefit: If successful, patients may experience faster recovery, less postoperative pain, and better return-to-work timelines with ultrasound-guided release.

How similar studies have gone: Previous nonrandomized studies have explored both approaches; this observational study adds real-world comparative data.
