Median nerve injury

The median nerve is a branch of the brachial plexus, innervating most of the flexor muscles in the forearm, most of the radial muscles in the hand, and providing sensory innervation to the radial side of the palm. Median nerve injury refers to functional impairment caused by damage to the median nerve due to various reasons, such as lacerations or compression from fractures. Clinical manifestations vary depending on the site of median nerve injury, primarily presenting as sensory and functional deficits in the arm.
