Abstract

Methods: We prospectively examined 102 wrists of 51 patients with clinical CTS, which were classifed into 3 groups according to the electrodiagnostic (EDX) fndings. Median nerve CSAs were measured using 3D US at the carpal tunnel inlet and at the level of maximal swelling.

Results: then wrists were negative for CTS. Of the 92 CTS-positive wrists, 23, 30, and 39 were classifed as having mild, moderate, and severe CTS, respectively. The median nerve CSA differed signifcantly between the severe- and moderate-CTS groups (p=0.0007 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 infor mation about the severity of CTS, as indicated by the strong correlation with standard EDX fndings.

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) ultrasonogra-phy (US) and the electrophysiological severity of carpal tunnel syndrome (CTS).
