- Abstract
- Background and Purpose To determine the correlation between the cross-sectional area (CSA) Of the median nerve measured at the wrist using three-dimensional (3D) ultrasonography (US) and the electrophysiological severity of carpal tunnel syndrome (CTS). Methods We prospectively examined 102 wrists of 51 patients with clinical CTS, which were classified into 3 groups according to the electrodiagnostic (EDX findings. Median nerve CSAs Were measured using 3D US at the carpal tunnel inlet and at the-level of maximal swelling. Results Ten wrists were negative for CTS. Of the 92 CTS-positive wrists, 23, 30, and 39 were classified as having mild, moderate, and Severe CS, respectively. The median nerve CSA differed significantly between the severe- andmoderate-CTS groups,(p=00007 at the carpal tunnel inlet and p<0.0001 at the maximal swelling site). There was a correlation between median nerve CSA and EDX parameters among those wrists with severe and mild CTS (p<0.0001 at both sites). Conclusions The median nerve CSA as measured by 3D US could provide additional information about the severity of CTS, as indicated by the strong correlation with standard EDX findings.
