MRI of the median nerve and median artery in the carpal tunnel: prevalence of their anatomical variations and clinical significance

摘要

Objective Anatomical variations of the median nerve and the persistent median artery (PMA) in the carpal tunnel (CT) are important to understand for their clinical and surgical significance. The aim of this cohort retrospective study was to investigate the prevalence of aberrant median nerve branches and persistent median artery in the CT in a selected population using magnetic resonance imaging (MRI).
