Sonographic Measurement of Median Nerve Cross‐Sectional Area to Determine Severity of Carpal Tunnel Syndrome
Nathan J. Savage,
John S. McKell
Abstract:ObjectivesEvaluate the diagnostic accuracy of median nerve cross‐sectional area (CSA) to determine the severity of carpal tunnel syndrome (CTS) vs the presence of CTS across existing electrodiagnostic‐based (EDX) classification systems.MethodsRetrospective analysis of cross‐sectional patient data. Receiver operating characteristic (ROC) analysis was used to determine CSA cutoff values and associated diagnostic likelihood ratios for all consolidated and binary EDX‐based classifications of CTS severity.
