Deep peroneal nerve

Dr Grace Carpenter and Dr Henry Knipe et al.

The deep peroneal (fibular) nerve is one of two terminal branches of the common peroneal nerve.


Gross anatomy


Arises as one of two terminal branches of the common peroneal nerve deep to peroneus longus muscle.


Courses medially under peroneus longus muscle to pierce the inter-muscular septum. After entering the anterior compartment of the leg, it makes a sharp turn and courses inferiorly on the anterior aspect of the interosseous membrane accompanied by the anterior tibial vessels. The deep peroneal nerve passes under the extensor retinaculum at the ankle between the tendons of extensor hallucis longus and extensor digitorum longus along with the anterior tibial vessels.
