Carpal Tunnel Syndrome Evaluation With Ultrasound in Rheumatoid Arthritis Patients

In rheumatoid arthritis (RA) patients, the diagnosis of Carpal tunnel syndrome (CTS) was made based on clinical findings and physical examinations. Then, the cross-sectional areas of the participants' median nerves from different levels were measured. Meidolateral and anteroposterior diameter were measured at the level of the carpal tunnel inlet. Flattening ratio was calculated. wrist to forearm ratio and wrist to forearm difference were calculated. The obtained data were compared between RA with CTS, RA without CTS and healthy control.
