Median nerve neuropathy is a median nerve affection, which appears as sensory and motor disorders in the zone of its innervation (in 1st, 2nd and 3rd fingers).
In most of cases, the median nerve compression occurs at the wrist level, in the carpal tunnel due to prolonged repetition of hand flexion and extension (while working at computer). This type of neuropathy is also called carpal tunnel syndrome (CTS).
Median nerve neuropathy is characterized by the formation of a “monkey’s arm”, arising due to muscle hypotrophy in the 1st finger elevation area. A hand flexion and the 1st, 2nd, 3rd fingers flexion are weakened; sensitivity decrease of the palmar surface of these 3 fingers, the adjacent half of the ring finger, and the radial edge of the hand. The pains arising from the median nerve neuropathy are quite significant and causalgic, i.e. painful, burning, conditioned by the sympathetic nerve fibers involvement.
