It gives the aural communicating nerve which joins the sural nerve in the midcalf. Clinical significance Chronic fibular (peroneal) neuropathy can result from, among other conditions, bed rest of long duration, hyperflexion of the knee, peripheral neuropathy, pressure in obstetric stirrups, and conditioning in ballet dancers. The most common cause is habitual leg crossing that compresses the common fibular nerve as it crosses around the neck of the fibula. Transient trauma to the nerve can result from peroneal strike. Damage to this nerve typically results in foot drop, where dorsiflexion of the foot is compromised and the foot drags (the toe points) during walking; and in sensory loss to the dorsal surface of the foot and portions of the anterior, lower-lateral leg. A common yoga kneeling exercise, the Vajrasana, has been linked to a variant called yoga foot drop. Surgical procedures involving the nerve involve: fibular (peroneal) nerve decompression To surgically decompress the common fibular nerve, an incision is made over the neck of the fibula. Fascia surrounding the nerves to the lateral side of the leg is released. Deep fibular (peroneal) nerve decompression 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 fibular nerve, putting pressure on it and causing pain, is released. Autopsy Anatomists are taught not to divide this nerve during its revealing. (Considering the fact that the most of them exploit this knowledge during their surgical praxis.)
