Abstract

The anterior interosseous nerve is the largest muscular branch of the median nerve and typically supplies the flexor digitorum profundus (radial part), flexor pollicis longus, and the pronator quadratus. Isolated paralysis in the distribution of the interosseou nerve of the forearm has been reported by several workers. This syndrome is distinguished by the absence of sensory involvement combined with partial median nerve paresis. This is a syndrome which is casily overlooked or misconstrued, unless the exact motor distribution of the anterior interosseous nerve is understood. We experienced a case following hard exercise in which the anterior interosseous nerve was compressed by the fibrous compression band on the underside of the flexor digitorum superficialis.
