Ultrazvuková korelace středně těžkého až těžkého syndromu karpálního tunelu / Median Nerve Ultrasonography Examination Correlates for the Diagnosis of Moderate to Severe Carpal Tunner Syndrome

Median Nerve Ultrasonography Examination Correlates for the Diagnosis of Moderate to Severe Carpal Tunnel Syndrome Objective: The aim of the study was to investigate the associations of cross-sectional area (CSA) of the median nerve measured by ultrasonography (US), the median to ulnar nerve ratio (MUR), the median to ulnar nerve difference (MUD) and the ratio of CSA of the median nerve to height squared (MHS) in relation to electrodiagnostic classification of moderate and severe carpal tunnel syndrome (CTS) and thus to identify patients suitable for surgical treatment. Materials and Methods: A prospective study was conducted in patients aged ≥ 18 years who underwent both median and ulnar nerve US and electrodiagnostic studies (EDS). 124 wrists of 62 patients were examined. The patients' characteristics were acquired through a questionnaire. CTS was diagnosed using EDS and classified according to the guidelines of the Czech Republic Association of Electrodiagnostic Medicine. The CSA of the median nerve and of the ulnar nerve were measured at the carpal tunnel inlet, i.e. at the level of the pisiform bone. Results: The median nerve swells at the wrist in CTS. Median nerve CSA at the tunnel inlet ≥ 12mm2 correlates with electrodiagnostic classification of moderate to severe carpal tunnel syndrome. At...
