Abstract: (7235 Views)
Carpal tunnel syndrome which is median nerve entrapment neuropathy, is the most frequent occupational disease. Diagnosis is mainly made by electrodiagnostic study but there is no specific exam for screening of patients. In study of 101 hands(55 patients) with CTS (confirmed by electrodiagnostic study), wrist-squareness. Ratio(thickness/width=T/W) were measured. Correlation between T/W>0.7 & DL>4.2 (distal latensy=DL) were assessed In order to find whether or not T/W> 0.7 would indicate a median nerve sensory latency greater than 4.2ms, as a predictor of CTS. Results of this study indicate that: There is a positive correlation with T/W & DL. The sensitivity of T/W was 59.8%, so this ratio in screening of suspicious patients with CTS has limited value.
Keywords: Key Words: 1) CTS=Carpal tunnel syndrome 2) T/W=Thickness width ratio 3) DL= Distal latency
