Using ultrasound to analyze the carpal tunnel system

Ultrasound Analysis of Human Carpal Tunnel Synovium

Observational Mayo Clinic · NCT02747836

This study is testing a new ultrasound method to see if it can help doctors spot carpal tunnel syndrome earlier in patients before serious nerve damage happens.

What this trial studies

This observational study aims to develop a novel ultrasonographic method to assess the subsynovial connective tissue (SSCT) and measure the movement of tendons and nerves within the carpal tunnel. By identifying changes in the SSCT and median nerve motion, the study seeks to improve the early diagnosis of carpal tunnel syndrome (CTS) before significant nerve damage occurs. Current diagnostic methods often detect CTS at a late stage, leading to surgical interventions, whereas this approach may allow for non-surgical treatments to be more effective. The study will involve patients undergoing diagnostic workups for CTS, confirmed through clinical evaluation and nerve conduction studies.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing diagnostic evaluation for carpal tunnel syndrome who have clinically confirmed CTS.

Not a fit: Patients with conditions such as cervical radiculopathy, rheumatoid arthritis, or other specified exclusions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier diagnosis and treatment of carpal tunnel syndrome, potentially preventing permanent nerve damage.

How similar studies have performed: While ultrasound and MRI have been used in similar contexts, this specific approach focusing on SSCT is novel and has not been extensively tested.
