Is fibular nerve same as peroneal nerve?
The deep branch of the fibular nerve, also known as the deep fibular (peroneal) nerve, arises from the bifurcation of the common fibular nerve as well. This nerve runs through the interosseous membrane to enter the extensor (anterior) compartment of the leg for which it provides innervation.

Why is the deep fibular nerve compressed?
There are two main reasons why the deep fibular nerve could be compressed. The first is that the anterior leg muscles have been excessively used and so are compressing the nerve within the anterior compartment. The patient will experience pain in the anterior leg.

During the gait cycle for walking, dorsiflexion is required: When a person strikes their heel on the floor in the stance phase.
What is the deep fibular nerve?
Deep Fibular (Peroneal) Nerve. The deep fibular nerve was very recently known as the anterior tibial nerve. It begins at the bifurcation of the common fibular nerve, between the fibula and the proximal part of the fibularis longus. It passes obliquely forward, deep to the extensor digitorum longus, to the front of the interosseous membrane.
Where is the deep fibular nerve located?
The deep fibular nerve begins in the lateral compartment deep to the fibularis longus as one of the two divisions of the common fibular nerve, which was previously called the deep peroneal nerve. It continues around the fibular neck, piercing the anterior intermuscular septum, and runs obliquely forward between the extensor digitorum longus and tibialis anterior on the interosseous membrane, where it lies with the anterior tibial artery ( Figure 46.5 ). It descends with the artery and lies first lateral, then anterior, and finally lateral to it at the ankle, where it divides into its terminal branches.
What muscles does the tibialis anterior have?
In the leg, it supplies the four muscles of the anterior compartment: tibialis anterior, extensor digitorum longus, extensor hallucis longus, and fibularis tertius. It gives off an articular branch above the inferior extensor retinaculum to supply the ankle joint.
What are the four muscles of the anterior compartment?
The four muscles of the anterior compartment are the tibialis anterior, extensor digitorum longus, extensor hallucis longus, and fibularis tertius. As a group, these muscles originate at the proximal tibia, at the adjacent fibula, and at the interosseous membrane. All four muscles are innervated by the deep fibular nerve, and all four perform dorsiflexion as one of their primary actions.

How many terminal branches does the deep fibular nerve have?
The deep fibular nerve may end as three terminal branches instead of two. A number of variations in the digital distribution of the nerve have been reported. It may supply the medial side of the great toe, adjacent sides of the second and third toes, or the lateral 3.5 toes. The nerve may have no digital branches at all.
Where does the fibular nerve go?
The nerve then pierces the fascia of the leg to enter the anterior compartment of the leg. The common fibular nerve wraps around the fibular neck.

Why is the fibula nerve so close to the neck?
Injuries to the common fibular nerve are not uncommon due to the fact that this nerve is relatively unprotected. Its close proximity to the neck of the fibula makes it vulnerable to damage when the bone gets injured. The nerve can also be damaged due to compression caused by swelling or inflammation in the fibular compartment of the leg.
What is the root value of the common fibular nerve?
