title: The accessory deep peroneal nerve.
abstract: The innervation of the right M. extensor digitorum brevis was investigated in 52 subjects with the aid of stimulation electromyography. In 13 cases (25%) a particular branch of the superficial branch of the peroneal nerve, the accessory deep peroneal nerve, could be identified. In 1 case it alone, and in 12 cases, together with the deep peroneal nerve, innervated the M. ext. dig. brevis. The significance of the awareness of this anomalous innervation is pointed out.
