The Nervous system is the most complicated complex in the human body. It consists of the brain and spinal cord, as well as numerous branches. The latter provide instant impulses throughout the body. Violation of one nerve does not affect the functioning of the entire network. However, it can lead to a deterioration in the health of individual body parts.

Neuropathy is a disease characterized by non-inflammatory lesion of the nerves. Its development can contribute to degenerative processes, trauma or compression. The main target of the pathological process are usually of the lower extremity. neuropathy of the peroneal nerve

The So-called neuropathy of the legs is divided into the following types:

  • Pathology of the peroneal nerve;
  • Tibial nerve
  • Touch.

Each of these forms of disease is of great interest among physicians. Among all pathologies of the peripheral neuropathy of the peroneal nerve occupies a special place. That's about it and it will go later in the article.

Description of the disease

Under the neuropathy of the peroneal nerve refers to a pathological disorder characterized by syndrome of drooping of the foot. In the specialized literature can be found another name for this disease — peroneal neuropathy.

Because the peroneal nerve is composed of thick fibers with an impressive layer of the myelin sheath, it is more susceptible to metabolic disorders. Most likely, this moment causes the prevalence of the disease. According to reports, the manifestations of the pathological process observed in 60% of patients of traumatologic offices, and only in 30% of cases it is associated with primary damage to the nerve.

Next, consider the anatomical features described in the article structure. It is necessary to understand the reasons for developing neuropathy of the peroneal nerve (ICD-10 assigned disease code G57.8).

Anatomical reference

The Peroneal nerve departs from the ischium at the level of the lower third of the thigh. Its structure is represented by different fibers. At the level of the popliteal fossa, these elements are separated in the common peroneal nerve. He spirals avoids the head bone of the same name. In this place the nerve lies on the surface and covered only with skin, causing any external factors can exert pressure on him.

Then peroneal nerve divides into two branches: superficial and deep. These elements have received the name thanks to his direction. Superficial branch is responsible for the innervation of the muscle structures, the rotation of the foot and the sensitivity of her backside. Deep fibular nerve provides straightening the fingers and also the sensation of pain and touch in this area.

Compression of one or other of the branches is accompanied by the violation of the sensitivity in different zones of the foot, inability to straighten the phalanx. Therefore, the symptoms of neuropathy can vary depending on which Department structure is damaged. In some cases, knowledge of the anatomical features to determine the degree of the pathological process before seeking medical attention.

Main causes of disease

The Development of the pathological process can be caused by many factors. Among them, the doctors are the following:

  • Nerve Compression at any section of the route. This so-called tunnel neuropathy of the peroneal nerve. It is divided into two groups. Upper syndrome develops on the background pressure on the structure in the vascular bundle. The disease is most commonly diagnosed in people whose work is associated with prolonged stay in an uncomfortable position. This gathering berries, parquet layers, seamstresses. The lower tunnel syndrome develops as a result of compression of the deep peroneal nerve in the area to the foot. Such clinical picture is characteristic for people who prefer uncomfortable shoes.
  • Circulatory disorders in the limbs.
  • Incorrect positioning of the feet due to prolonged operation or serious condition of the patient, accompanied by immobilization.
  • Getting into the fibers of the nerve by intramuscular injection in the gluteal region.
  • Severe infections.
  • Traumas (fracture of the tibia, dislocation of the foot, tendon damage, sprains). As a result of severe injury there is swelling. It leads to compression of the nerve and deterioration of conductivity pulses. A distinctive feature of this form of the disease is the involvement of only one extremity. Otherwise, it is called post-traumatic neuropathy of the peroneal nerve.
  • Cancer lesions with metastasis.
  • Toxic pathology (diabetes mellitus, kidney failure).
  • Systemic disease characterized by proliferation of connective tissue (osteoarthritis, gout, rheumatoid arthritis).

All causes of development of pathological process can be categorized in five areas: trauma, compression, vascular disorders, infectious and toxic shock. Regardless of what the trigger group is the neuropathy of the peroneal nerve, code by ICD-10 have this disease is one — G57.8.

What symptoms accompany the disease?

The Clinical manifestations of the disease depend on the degree of neglect of pathologicalprocess space of the nerve damage. All the symptoms can be divided into basic and related. The first group is the disturbance of sensation in the affected limb. Accompanying symptoms may vary in each case. However, patients often complain of:

  • Swelling in the legs;
  • Periodic sensation “chills”;
  • Spasms and cramps;
  • Discomfort when walking.

Just above it was noted that the clinical picture of the disease also depends on the location of the nerve damage. For example, the defeat of the common stem there is a violation of the process of extension of the foot. Because of this, it begins to droop downward. When walking the patient is forced to constantly bend the leg at the knee, so as not to catch a foot over the floor. When lowering it first gets on your fingers, then transfer weight to the lateral plantar region, and only then lowers the heel. This style of movement resembles a cock, or a horse, and therefore carries a similar name.

neuropathy of the peroneal nerve symptoms

Movement disorders are combined with sensory disorders. Patients often note the appearance of pain on the outer surface of the tibia, which only intensified when squatting. Over time, the affected area develops muscle atrophy. This sign of disease is visible, especially when compared with the healthy limb.

What is neuropathy of the peroneal nerve symptoms in lesions of the deep branch? In this case, the overhang of the foot is expressed less explicitly. However, sensory and motor disturbances are also present. If the disease is not treated, it is complicated by atrophy of the small muscles.

Neuropathy of the peroneal nerve in lesions of the superficial branch is accompanied by disturbance of sensation and severe pain in the lower part of the calf. During the examination, patients are often diagnosed the weakening of the pronation of the foot.

Diagnostic Methods

The Timely detection of the pathological process and eliminate the underlying disease — these two factors are key to successful therapy. How is the diagnosis of neuropathy?

First, the doctor collects the medical history of the patient. In this procedure, he studies his map of diseases and conducts a survey to clarify information. The doctor then proceeds to instrumental methods of diagnosis. To assess muscle strength are certain tests and analysis of skin sensitivity by means of special needles. In addition, use of electromyography and together. These procedures allow to establish the degree of nerve injury. No less informative method of examination is considered an ultrasound during which the doctor can examine the damaged structure.

Neuropathy peroneal nerve always requires a differential diagnosis with other disorders that have similar clinical manifestations. Among them include the disease Charcot-Marie-tooth syndrome peroneal muscular atrophy, cerebral tumour.

In particularly serious cases requiring consultation with specialists. For example, of trauma. On the basis of the results already obtained of the tests your doctor may order x-rays of bones or knee joint.

The Neuropathy of the peroneal nerve: ICD

To understand the doctor delivered the diagnosis, you need to get acquainted with a special system of codes. They are recorded in the International classification of diseases (ICD). The system is built is very simple. First is the designation of a Latin letter, which defines a group of diseases. Followed by a numeric code that indicates a particular disease. Sometimes you can find another symbol. It carries information on the varieties of the disease.

Many patients are interested in what is code (IBC) neuropathy of the peroneal nerve. It should be noted that as such designations have described disease no. To category G57 are mononeuropathy lower extremities. If you delve into the study of pathologies that belong to this class, our disease there will not meet. However, it is possible to include code G57.8, which refers to other monoaural lower limbs.

Knowing that is a the international classification of diseases, you can get any information on the question of diagnosis. This applies to such disease as neuropathy of the peroneal nerve. ICD-10 has assigned him the code G57.8.

Principles of therapy

Treatment of the pathology is determined by its cause. Sometimes it is enough to replace a plaster bandage, which compresses the nerve. If the role of a provoking factor is uncomfortable shoes, a new pair of shoes can also become the solution.

Often, patients come to the doctor with a “bouquet” of comorbidities. Diabetes, cancer or kidney failure — these disorders can cause such illness like neuropathy of the peroneal nerve. Treatment in this case is to remove the primary disease. Other measures will be mostly indirect.

Therapy medicinal products

The Main medicines used in the treatment of neuropathy, are the following:

  • Non-Steroidal anti-inflammatory drugs (“Substance”, “Nimesulide”, “Xefocam”). They help to reduceswelling and pain, remove the symptoms of inflammation. NSAIDs are often prescribed for diagnosis “axonal neuropathy peroneal nerve”.
  • B Vitamins
  • Antioxidants (“Berlition”, “Thiogamma”).
  • Tools for improving the conductivity of impulses along the nerve (“Neostigmine”, “Neiromidin”).
  • Drugs to restore blood circulation in the affected area (“Kaviton”, “Trental").

This list describes only some of the medicines. In each case the choice of drugs depends on the clinical picture of the disease and earlier ailments.


Various physiotherapy activities are well established in the treatment of neuropathy. Usually the doctors recommend the following procedure:

  • Magnetoterapia;
  • Electrostimulation;
  • Massage;
  • Refleksoterapii;
  • LPC.

Special efficacy differs massage for neuropathy of the peroneal nerve. But this procedure at home is unacceptable. Massage should be done by a qualified technician. Otherwise it is possible not only to suspend the process of treatment, but also harm their health.

The same recommendations indicated for physical therapy. It is worth to mention that the first sessions should be supervised by an experienced coach. Then repeat the exercises at home.

If conservative treatment for several weeks shows its ineffectiveness, the doctor decides on the surgery. It is usually administered in the case of traumatic damage of nerve fibers. Depending on the clinical picture and the patient's General condition possible to carry out decompression of the nerve, neurolysis or grafting.

After surgery requires a long recovery period. At this time the patient should limit physical activity to do physical therapy. Every day is necessary to examine the affected limb for cracks and wounds. In the case of detection, the leg should be fully rest. For this purpose, use special crutches and the wound treated with antiseptics. Other recommendations the doctor gives individually.


What awaits the outcome of patients diagnosed with “neuropathy of the peroneal nerve”? The treatment of the disease largely determines the prognosis for recovery. If the timely initiation of the therapy and follow all recommendations of your doctor, you can hope for a positive result. Complicated course of the disease and delayed medical treatment exacerbate the situation. In this case, patients often lose the ability to work.

Brief summary

Neuropathy of the peroneal nerve is a serious disease. Its basis may lie cardiovascular disorders, intoxication and toxic lesions. However, the main reason of development of pathological process is still considered the injury of various origins.

The Main symptoms associated with impaired motor activity of the limbs, and therapeutic strategy is largely determined by the factors that contributed to the development of the disease. Your doctor may prescribe drug therapy or physiotherapy. In rare cases require surgical intervention.
