Median nerve cross sectional area at the distal wrist and nerve conduction findings in patients with carpal tunnel syndrome: A comparative study

Carpal tunnel syndrome (CTS) is the most common form of peripheral entrapment neuropathy.Ultrasound (US) has emerged as a valuable diagnostic tool for musculoskeletal conditions, including CTS.The aim of the present study was to evaluate the correlation between the cross-sectional area of the median nerve (MN) at the distal wrist (CSA-D) with the severity of CTS, as determined by nerve conduction studies (NCS).For this purpose, a total of 60 female patients with clinical CTS symptoms underwent ultrasound CSA-D measurements at the carpal tunnel inlet, followed by NCS by a blinded electrophysiologist to the US findings.The results revealed that CSA-D exhibited a significant positive correlation with MN distal motor latency (R=0.588,P
