Abstract
Percutaneous ultrasound-guided release of carpal tunnel syndrome is an effective and safe technique; however, it requires familiarity with ultrasound visualization of the anatomical structures involved. This study aimed to determine the learning curve for percutaneous ultrasound-guided release of the carpal tunnel. We conducted a prospective, observational, analytical cohort study on patients treated for carpal tunnel syndrome using the percutaneous ultrasound-guided technique. We assessed the learning curve using complication rates, duration of procedure and conversion rate to open surgery. Eighty patients with a mean age of 58 years were included. The surgical time gradually decreased, stabilizing after the first 30 procedures. There were no intraoperative complications and no cases requiring conversion to open surgery. Based on our experience, the learning curve for percutaneous ultrasound-guided release of carpal tunnel syndrome is approximately 30 procedures. Clinical outcomes were not affected by the learning curve.
