Compound muscle action potential cartography of an accessory peroneal nerve.
In daily practice, accessory peroneal nerves (APNs) are detected in less than the 18-25% of legs, as revealed by systematic searches. In one APN case, compound muscle action potential cartography showed that the APN was only apparent when the recording electrode was placed over a small lateral region of the extensor digitorum brevis muscle. Effects of recording site can explain why many APNs go unrecognized.
