Comparison of ultrasound and magnetic resonance imaging of the median nerve's recurrent motor branch and the value of its diameter in diagnosing carpal tunnel syndrome.

ABSTRACT:

Background

Anatomical variations of the recurrent motor branch (RMB) are at risk of injury during carpal tunnel release procedures. Previous studies have visualized the RMB using ultrasound (US) and magnetic resonance imaging (MRI) but have not compared the imaging capabilities of the two. Previous investigations have overlooked two specific types of carpal tunnel syndrome (CTS): simultaneous compression of the median nerve and the RMB and isolated compression of the latter. This study aims to identify the best imaging method to prevent iatrogenic injury to the RMB by comparing US and MRI capabilities. It also aims to devise a new method for the comprehensive diagnosis of CTS by evaluating the initial diameter of the RMB (RMB-ID). Additionally, this study aims to gain insights into
