An Unnerving Cause of Hand Pain – Carpal Tunnel Syndrome with Accessory Flexor Digitorum Superficialis Indicis interposing a Bifid Median Nerve - Abstract
Anatomical variations, such as a bifid median nerve, have been reported as potential contributing factors for the development of carpal tunnel syndrome (CTS). These anomalies are typically diagnosed intraoperatively. With the growing use of sonography as adiagnostic tool, the prevalence of bifid median nerves has increased from 2.8% to 15.4-19%. We report on a case of CTS in an individual with a bifid median nerve and an accessory flexor digitorum superficialis indicis bisecting the two divisions of the median nerve that was diagnosed with sonography. Use of sonography can aid in procedural management of patients with CTS.
