Methods: Two hundred patients (400 hands) were submitted to wrist US to measure mediannerve area (MNA), questioning on paresthesia and pain in the median nerve territory, Tineland Phalen maneuvers. An MNA > 9 mm2 was considered diagnostic of CTS. Results: Measurement of MNA by US was > 9 mm2 in 27% of the hands. A good association with pain (p < 0.0001), paresthesia (p < 0.0001), Tinel test (p < 0.0001) and Phalen test (p < 0.0001) was found. According to the clinical criteria for classification of CTS from American Academy of Neurology the MNA by US had 64.8% of sensibility and 77.0% of specificity in this sample. Conclusion: Measurement of MNA by US performs well and can be used as first option for the investigation of patients with CTS.
