Deep Fibular Nerve

Deep fibular nerve and its branches

The Deep Fibular Nerve (also known as the Deep Peroneal Nerve) is a branch of the Common Fibular Nerve, which itself is a branch of the Sciatic Nerve. It provides motor innervation to the muscles of the anterior compartment of the leg and sensory innervation to the skin between the first and second toes.

Anatomy

The Deep Fibular Nerve originates from the Common Fibular Nerve, which splits into the Deep Fibular Nerve and the Superficial Fibular Nerve at the level of the neck of the Fibula. It then descends into the anterior compartment of the leg, innervating the Tibialis Anterior, Extensor Hallucis Longus, Extensor Digitorum Longus, and Peroneus Tertius muscles.

Clinical Significance

Damage to the Deep Fibular Nerve can result in Foot Drop, a condition characterized by the inability to lift the front part of the foot. This can be caused by a variety of conditions, including Diabetes, Lumbar Disc Herniation, and Charcot-Marie-Tooth Disease.
