deep peroneal nerve

It can be caused by damage to the deep peroneal nerve.

Deep peroneal nerve decompression:

The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve).

The anterior tibial vessels and deep peroneal nerve lie between it and the Tibialis anterior.

The common peroneal nerve branches to form the superficial and deep peroneal nerves, both of which supply extensor muscles of the foot.

The tibialis anterior overlaps the anterior tibial vessels and deep peroneal nerve in the upper part of the leg.

It is innervated by the deep peroneal nerve and acts as both an antagonist and a synergist of the tibialis posterior.

It also supplies the integument of the medial side of the foot and ankle, and communicates with the saphenous nerve, and with the deep peroneal nerve.

Toe extensors (extensor hallicus longus, extensor digitorum longus) are innervated by the deep peroneal nerve.

Nerve supply: lateral terminal branch of Deep Peroneal Nerve (deep fibular nerve) (proximal sciatic branches S1,S2).

In the surgical treatment of deep fibular nerve entrapment in the foot, a ligament from the extensor digitorum brevis muscle that crosses over the deep peroneal nerve, putting pressure on it and causing pain, is released.

The deep peroneal nerve innervates the muscles of the anterior compartment of the leg which are: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and the fibularis (peroneus) tertius.

The structures of anterior compartment can be remembered using the mnemonic, "TEA DEPt" for Tibialis anterior, Extensor hallucis longus, Anterior tibial artery, Deep peroneal nerve, Extensor digitorum longus and Peroneus tertius.
