Nerve: Deep fibular nerve
Nerves of the right lower extremity Posterior view.
Latin	nervus fibularis profundus, nervus peronæus profundus
Gray's	subject #213 965
Innervates	anterior compartment of leg
From	Common Fibular (peroneal) nerve

The deep fibular nerve (deep peroneal nerve) begins at the bifurcation of the common fibular nerve, between the fibula and upper part of the fibularis (peronæus) longus, passes infero-medially, deep to extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior tibial artery above the middle of the leg; it then descends with the artery to the front of the ankle-joint, where it divides into a lateral and a medial terminal branch.

It lies at first on the lateral side of the anterior tibial artery, then in front of it, and again on its lateral side at the ankle-joint.

In the leg, the deep fibular nerve supplies muscular branches to the tibialis anterior, extensor digitorum longus, fibularis (peronæus) tertius, and extensor hallucis longus (propius), and an articular branch to the ankle-joint.
