Assessment of diagnostic efficiency of real-time strain elastography by using the median nerve stiffness at females with carpal tunnel syndrome
Abstract
elastography in relation to carpal tunnel syndrome (CTS) and to show the relationship between electromyography (EMG) and sonographic cross-sectional area measurements.
Materials and Methods: The patients with paresthesia of the median nerve distrubition lasting at least for 3 months were included. A total of 23 female patients’s of CTS and 25 healthy female volunteers’ wrist in which one median nerve existed included that of 36 CTS and 46 healthy wrists. The patients had clinical signs and their EMG test confirmed the diagnosis. The patients median nerve along its course on the wrist was applied strain elastography at three points of the radioulnar joint, scaphoidpsiform junction and hamate bone.
Results: The EMG findings, strain elastogragraphy ratios and the CSA of the median nerve were found to be correlated significantly. The median nerve strain ratio in elastography was significantly increased in the CTS patients compared to the control group.
Conclusion: Sonoelastography promises to be a useful method for the diagnosis of CTS.
