what is a bifid median nerve
A detailed description of the anatomical variations of the median nerve in the carpal tunnel, including the bifid median nerve, was previously reported. The bifid median nerve is a cause of secondary carpal tunnel syndrome due to its relatively higher cross-sectional area compared with a nonbifid median nerve. Magnetic resonance imaging (MRI) and ultrasound can be obtained to show bifid median nerves, helping surgeons avoid potential surgical hazards.
