The median nerve arises from the medial and lateral cords of the brachial plexus, representing the root level of C5 to T1 levels, which is a mixed sensory and motor nerve. As a single nerve, the median nerve enters underneath the flexor retinaculum in the palmar wrist region. It then bifurcates distally into medial and lateral branches, whose sensory branch supplies the first three and a half portions of fingers, and a thenar motor branch which supplies the thumb (abductor pollicis brevis, opponens pollicis, and the superficial head of the flexor pollicis brevis) and the lateral two lumbricals of the hands. A bifid median nerve (BMN) is present when this bifurcation occurs proximal to the flexor retinaculum. This anatomical variant increases the chance for patients to develop symptoms of carpal tunnel syndrome. The median nerve has its own blood supply arising from the axial artery, known as the median artery. It arises from the common interosseous artery, which is a branch of the ulnar artery called the anterior interosseous artery (Park et al., 2021). The median artery runs along the median nerve up to the palm and is anastomosed with the superficial palmar arch. It remains to be the predominant blood supply to the thumb. By the eighth week of gestation, it usually regresses. It can remain patent and may be present in any of these two forms: persistent median artery (PMA) in the forearm (antebrachial type) or persistent median artery at the palm (palmar type) (Solewski et al., 2021). It then pierces the median nerve bundle at the perineurium and separates the nerve into two (bifid) or three (trifid) bundles. A bifid or trifid median nerve can exist without a persistent median artery (Asghar et al., 2022).
