What does the peroneal nerve control?

The common peroneal nerve branches from the sciatic nerve and provides sensation to the front and sides of the legs and to the top of the feet. This nerve also controls the muscles in the leg that lift the ankle and toes upward.

What muscles are controlled by the peroneal nerve?

The deep peroneal nerve provides motor innervation to the four muscles of the anterior compartment: the tibialis anterior, extensor digitorum, extensor hallucis longus and peroneus tertius muscle.

What nerve Innervates peroneus brevis?

superficial peroneal nerve
The superficial peroneal nerve supplies motor innervation to the following muscles: Peroneus longus muscle. Peroneus brevis muscle.

What causes common peroneal nerve pain?

Common causes of damage to the peroneal nerve include the following: Trauma or injury to the knee. Fracture of the fibula (a bone of the lower leg) Use of a tight plaster cast (or other long-term constriction) of the lower leg.

What causes common peroneal nerve entrapment?

Common peroneal nerve entrapment is usually due to scar tissue in the region of the common peroneal nerve, which can lead to localized pain, numbness over the anterior and lateral aspects of the leg and foot, and weakness of the foot in dorsiflexion, toe extension, and foot eversion.

What does common peroneal nerve supply?

The nerve can be palpated behind the head of the fibula and as it winds around the neck of the fibula. The common fibular (peroneal) nerve gives articular branches to the knee and superior tibiofibular joint. The lateral cutaneous nerve of the calf supplies the posterolateral side of the proximal two-thirds of the leg.

What does the perineal nerve innervate?

The deep branch of the perineal nerve pierces the medial wall of the pudendal canal and goes on to innervate the levator ani and the external anal sphincter. After this, the deep branch passes to supply the bulbospongiosus, ischiocavernosus, superficial transverse perineal muscle, and bulb of the penis.

Is peroneal nerve damage painful?

Severe nerve damage may cause permanent disability. The nerve pain may be very uncomfortable.

How do you treat common peroneal nerve damage?

Treatment of Common Peroneal Nerve Entrapment begins with rest, splinting the ankle in the neutral position, non-steroidal anti-inflammatory drugs to reduce the swelling and inflammation, diet and exercise in obese patients, and strict glucose control in diabetics.

What happens if the common peroneal nerve is damaged?

When the nerve is injured and results in dysfunction, symptoms may include: Decreased sensation, numbness, or tingling in the top of the foot or the outer part of the upper or lower leg. Foot that drops (unable to hold the foot up) “Slapping” gait (walking pattern in which each step makes a slapping noise)

How do you fix peroneal nerve entrapment?

Can peroneal nerve damage be reversed?

Although in most cases they recover spontaneously, an irreversible damage of the nerve is also likely to occur. Nerve regeneration following CPN repair is poorer if compared to other peripheral nerves and this can explain the reluctant attitude of many physicians towards the surgical treatment of these patients.
