The potential value of ultrasonography in the evaluation of carpal tunnel syndrome

Abstract

The authors compared ultrasonography with electrophysiology for the diagnosis of carpal tunnel syndrome (CTS) on 110 clinically affected wrists. An increased cross sectional area in the proximal carpal tunnel larger than 0.11 cm(2) in combination with compression signs on longitudinal scans proved to be highly predictive for CTS (sensitivity, 89.1%; specificity, 98.0%). Ultrasound was comparable to electrophysiology in the diagnosis of CTS, and in 35% of cases changes in morphology suggested a specific therapeutic strategy.
