The anterior interosseous nerve is the largest branch of the median nerve. The anterior interosseous nerve syndrome is a rare focal neuropathy with typical clinical and electromyographic features. Most commonly reported etiologies include fracture of the forearm and arm, trauma or prolonged pressure on the forearm.
A 26-year-old man was evaluated for weakness of the flexor pollicis longus, the second flexor digitorum profundus and the pronator quadratus muscles that occured following bowling.
We report one case of anterior interosseous nerve syndrome following bowling, which was not related to trauma.
