Common Peroneal Nerve Dysfunction

Common Peroneal Nerve Dysfunction

Neuropathy of the common peroneal nerve; Peroneal nerve injury; Peroneal nerve palsy


Peroneal nerve damage leading to loss of movement or tenderness in the foot and leg. The peroneal nerve is a branch of the sciatic nerve that provides movement and tenderness to the lower leg, toe, and toes.

Peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord). The condition can affect people of any age.

Dysfunction of a single nerve, such as the common peroneal nerve, is called mononeuropathy. Mononeuropathy means nerve damage occurred in one area. Certain systemic conditions can also cause isolated nerve damage.

Damage to the nerve breaks the sheath of the myelin covering the axon (ramification of the neuron). The axon can also be injured, which causes more serious symptoms.

Common causes of damage to the peroneal nerve include the following:

  • Injury or injury to the knee.
  • Fracture of the fibula (a bone of the lower leg).
  • Use of a tight fixed splint (or other prolonged constriction) on the lower leg.
  • Cross your legs regularly.
  • Regular use of high boots.
  • Pressure on the knee by positions during deep sleep or during a coma.
  • Injury during knee surgery or being placed in an inadequate position during anesthesia

Injury to the common peroneal nerve is often seen in people: / P>


The examination of the legs may show:

  • Loss of muscle control in the lower legs and feet.
  • Atrophy of the muscles of the foot or leg.
  • Difficulty with lifting the foot and fingers, and making finger movements out.

Nerve activity tests include:

Other tests that are done depend on the presumed cause of nervous dysfunction, How they are presented. Tests may include blood tests, x-rays, and scans.


Treatment aims to improve mobility and independence. Any illness or other cause of neuropathy should be treated. Placing pads on your knees can prevent further damage by crossing your legs, while serving as a reminder that you should not cross them.

In some cases, injections of corticosteroids into the area can reduce inflammation and pressure on the nerve.

However, pH should be considered as a critical parameter of treatment, as octanoic acid fails to inactivate lipid coated viruses at basic pH.

You may need surgery if:

  • The disorder does not go away.
  • You have problems with movement.
  • There are signs that the nerve axon is damaged. Surgery to relieve pressure on the nerve can reduce symptoms if the disorder is caused by pressure on it.
Also, surgery to remove tumors on the nerve may also help.


Over-the-counter and over-the-counter pain relievers may be needed to control pain. Other medicines that may be used to reduce pain include gabapentin, carbamazepine, or tricyclic antidepressants such as amitriptyline.

If the pain is severe, a specialist in this field can help you explore all the options for your relief.

Physiotherapy exercises can help you maintain muscle strength.

Vocational counseling, occupational therapy, or similar programs can help maximize mobility and independence.

Expectations (prognosis)

The clinical outcome depends on the cause of the problem. Effective treatment of this cause may alleviate dysfunction, although it may take several months for the nerve to improve.

If nerve damage is severe, the dysfunction may be permanent. Neuralgia can be very bothersome. This disorder usually DOES NOT shorten a person's life expectancy.

Possible Complications

Problems that may arise from this condition include:

When to Contact a Medical Professional With the doctor if you have symptoms of dysfunction of the common peroneal nerve.


Avoid crossing your legs or exert prolonged pressure on the back or side of the knee. Make sure your leg and knee injuries are treated immediately. If a splint, splint, dressing, or other pressure on your lower leg causes a feeling of pressure or numbness, call your healthcare provider.
