Proximal median neuropathies

Proximal median neuropathies are uncommon. They are usually caused by overuse of the forearm, anatomic variations, or both. Forearm pain, weakness of muscles supplied by the affected nerves, and sensory loss, including the thenar eminence, are common clinical findings. Nerve conduction studies and needle electromyography are helpful in the diagnosis of these syndromes. Treatment is avoidance of overuse and release of mechanical compression. Prognosis is generally good.
