What is the sensory innervation of the ankle joint?

Numerous branches of the sural nerve are involved in the sensory innervation of the ankle joint. The superficial peroneal nerve innervates the peroneus longus and brevis muscles myokinetically and follows these to the distal section.

The dorsal aspect of the foot is innervated by 3 nerves that run on the anterior side of the lower leg and ankle — the superficial peroneal, deep peroneal, and saphenous nerves. The volar aspect of the foot is innervated by the posterior tibial and sural nerves on the posterolateral aspect of the ankle.

Additionally, what nerve goes to second toe? Innervation: The medial and lateral plantar digital nerves to the second toe, dorsal cutaneous innervation can also be used via the deep peroneal nerve.

In this regard, what nerve Innervates the ankle extensors?

Function. In the leg, the deep peroneal nerve supplies muscular branches to the anterior compartment of extensor muscles in the leg which include the tibialis anterior, extensor digitorum longus, peroneus tertius, and extensor hallucis longus (propius), and an articular branch to the ankle-joint.

What nerve Innervates the arch of the foot?


What does nerve damage in the ankle feel like?

People with tarsal tunnel syndrome may experience pain, numbness, or tingling. This pain can be felt anywhere along the tibial nerve, but it’s also common to feel pain in the sole of the foot or inside the ankle. This can feel like: sharp, shooting pains.

How do you treat nerve damage in the ankle?

Treatment Your provider will likely suggest first resting, putting ice on the ankle, and avoiding activities that cause symptoms. Over-the-counter pain medicine, such as NSAIDs, may help relieve pain and swelling. If symptoms are caused by a foot problem such as flat feet, custom orthotics or a brace may be prescribed.

Can you get a trapped nerve in your ankle?

Foot and ankle pain that occurs with numbness and weakness in your foot may be caused by a pinched nerve in your ankle (tarsal tunnel syndrome) or back (sciatica). Burning, numbness, or lack of feeling in your feet may be caused by poor circulation, especially in people who have diabetes or peripheral arterial disease.

How do you fix nerve damage?

Depending on the type and severity of your nerve injury, you may need medications such as aspirin or ibuprofen (Advil, Motrin IB, others) to relieve your pain. In some cases, you may need corticosteroid injections to relieve your pain.

Can exercise damage nerves?

Even slight nerve compression can reduce the blood flow to the nerve, making it more sensitive. If a nerve cannot handle the task of exercise, there may be increased pain, tingling or numbness, or even increased muscle weakness during or after the exercise.

Can stretching cause nerve damage?

Stretching or pressing on a nerve can cause injury. The nerves also may be damaged as a result of other health conditions that affect the nerves, such as diabetes or Guillain-Barre syndrome. In more-severe peripheral nerve injuries both the fibers and the insulation are damaged, and the nerve may be completely cut.

What happens when you sprain an ankle?

An ankle sprain often occurs when the foot suddenly twists or rolls, forcing the ankle joint out of its normal position. This causes one or more ligaments around the ankle to stretch or tear. Some swelling or bruising can occur as a result of these tears.

What does sural nerve pain feel like?

Sural neuritis leads to pain on the outside of the foot and ankle that is commonly described as burning in nature. The involved area is often hypersensitive to touch and there may be altered sensation, such as numbness, along the remaining course of the nerve.

What causes deep peroneal nerve damage?

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) Pressure to the knee from positions during deep sleep or coma.

What muscles are innervated by the deep fibular nerve?

The deep fibular nerve innervates the muscles in the anterior compartment of the leg, including: Tibialis anterior. Extensor hallucis longus. Extensor digitorum longus. Fibularis tertius.

What are symptoms of peroneal nerve damage?

Symptoms 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) Toes drag while walking. Walking problems. Weakness of the ankles or feet.

What causes foot inversion?

What Causes Foot Inversion? Foot inversion usually occurs as a result of poor posture in the foot. Inversion can creep in subtly as a result of weak inversion and eversion muscles, and is often hard to catch before injury occurs.

What nerve inverts the foot?

Clinical Relevance: Damage to the Tibial Nerve Damage results in loss of plantar flexion, loss of flexion of toes and weakened inversion (The tibialis anterior can still invert the foot). The tibial nerve is a major peripheral nerve of the lower limb. It has several cutaneous and motor functions in the leg and foot.

Why does my extensor hallucis longus hurt?

Causes. Foot tendons can be irritated if they rub against shoes that are too tight. If you run and your running shoes or laces are pressing too hard against the tendons, the tendons can become inflamed. Overuse can also cause foot extensor tendonitis.
