Isolated high median nerve injuries.

High median nerve injuries are commonly associated with injury to the brachial artery and decreased sensibility typical for the pattern of innervation. Loss of motor function is to the interphalangeal joint of the thumb and index finger. Nerve suture was always successful in restoring some degree of sensibility. The return of action to the forearm flexors occurred in a predictable fashion 6-13 months after nerve suture.
