The common fibular nerve (common peroneal nerve; external popliteal nerve; peroneal nerve; lateral popliteal nerve), about one-half the size of the tibial nerve, is derived from the dorsal branches of the fourth and fifth lumbar and the first and second sacral nerves.

It descends obliquely along the lateral side of the popliteal fossa to the head of the fibula, close to the medial margin of the biceps femoris muscle. Where the common peroneal nerve winds round the head of the fibula, it is palpable.[1]

It lies between the tendon of the biceps femoris and lateral head of the gastrocnemius muscle, winds around the neck of the fibula, between the peronæus longus and the bone, and divides beneath the muscle into the superficial fibular nerve (superficial peroneal nerve) and deep fibular nerve (deep peroneal nerve).

It innervates the peroneus longus, peroneus brevis, and the short head of the biceps femoris muscles.

Branches[edit]

Previous to its division it gives off articular and lateral sural cutaneous nerves.

Clinical significance[edit]

Chronic 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 head of fibula.[2] 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 Varjrasana has, under the name "yoga foot drop," been linked to foot drop.[3][4]
