Ultrasound Findings in Less Frequent Causes of Carpal Tunnel Syndrome

Stefano Bianchi et al. J Ultrasound Med. 2020 Dec.

Abstract

The most common etiology of carpal tunnel syndrome (CTS) is idiopathic. However, secondary causes of CTS should be considered when symptoms are unilateral, or electrodiagnostic studies are discrepant with the clinical presentation. Imaging of the carpal tunnel should be performed when secondary causes of CTS are suspected. An ultrasound evaluation of the carpal tunnel can assess for pathologic changes of the median nerve, detect secondary causes of CTS, and aid in surgical planning.

Keywords: carpal tunnel syndrome; median nerve; tendons; ultrasound.
