Lasega symptom: the causes of appearance. Treatment of diseases accompanied by a symptom of Lasega

Lasegh's symptom in neurology was discovered by a French doctor and was later named after him. Even in the middle of the XIX century, the doctor noted: if the patient, lying on his back, raises his straightened leg, a sharp pain arises in the lumbar part of the body, which immediately passes when the person bends the limb.

Causes of appearance

Often, because of problems with the sciatic nerve , Lasega develops a symptom that accompanies the pinch or neuritis of this part of the CNS. This nerve is the largest in the human body, it is formed from branches branching from the spinal cord - the lumbar and sacral. It consists of two types of nerves: tibial and fibular. If they are excessively stretched, jammed or injured, the person feels strong pain when he is trying to lift his straight leg in a lying position.

The symptom arises from the inability of the nerve fibers to lengthen: its roots can be trapped in the holes between the vertebrae, or excessive stretching occurs in the case of a herniated intervertebral disc. When the patient lies in a relaxed state, he does not feel pain, since the sciatic nerve is idle at this time. But when he begins to lift the limb, the nerve is immediately stretched, causing painful sensations.

Three degrees of the syndrome

It is not necessary to be a doctor to determine Lacega's symptom: it can be found at home, having conducted an uncomplicated procedure. But it's better to contact a professional who will do it as high as possible. Diagnosis is as follows: the doctor asks the patient to lie down on the couch and move the limb. The higher the leg rises, the more pronounced the symptom is. The peak of pain usually occurs at a time when the limb is at an angle of 60º with respect to the surface.

Doctors at the same time distinguish three degrees of the syndrome Lasega:

• The first - the pain occurs only in the position of the foot at an angle of 60º.
• The second - acute painful sensations are characteristic at rise of a limb in 45º.
• Third - the patient can maximally raise his leg only by 30 °.

It is clear that the latter degree is characteristic of a more serious disease than the first. At the same time, the doctor is obliged to interrupt the diagnosis immediately, as soon as the patient is hurt. Otherwise, a person may have nerve fibers and, as a consequence, paralysis of the sciatic nerve.

Basic views

Medicine identifies three types of symptoms:

1. Positive symptom of Lasega. Occurs gradually when the leg is raised, but when it bends in the knee and hip joint disappears. Can talk about squeezing the sacral and lumbar roots, which often occurs with osteochondrosis and radiculitis.
2. Negative. When the limb is bent, the pain does not disappear. Physicians say that in this case it can be caused by the pathology of this part of the body. The patient is referred for an additional examination to find out the real causes of pain. By the way, they often have a psychological character: they are observed in hysterical women, depressed people.
3. Pseudo-positive symptom. It is found when the muscles of the back of the thigh muscles are very weak. Usually this is observed in elderly patients. In this situation, an orthopedic consultation is required.

Depending on the variety, the patient is prescribed appropriate therapy.

Osteochondrosis

This is one of the most common causes of pain. Lasega's symptom in osteochondrosis is characterized by acute pain, which spreads over the entire surface of the thigh. Its range is wide: from the buttocks and to the very feet. In such cases, the patient is prescribed medication. Treatment of osteochondrosis involves taking medications that belong to four groups:

• Medicines, which are based on vitamin D. It improves the absorption of calcium. Contraindication: increased content of this element in the patient's blood. Side effects are the formation of kidney stones.
• Preparations, whose action is aimed at reducing the calcium output from the bones and reducing pain. For example, "Alosteen" and "Calcitrine." In rare cases, the body reacts negatively to their reception: nausea, vomiting, hypertension develops.
• Therapy aimed at treating osteoporosis. This includes such drugs as "Bivalos", "Fosamax", "Bonviva". They block the process of bone resorption.
• Female hormones are estrogens. Among their functions is the prevention of increased fragility of bones. The most popular are "Proginova", "Klimonorm" or "Estron".

In addition to medicines, the patient is prescribed exercise therapy and other necessary procedures.

Radiculitis

The causes of the appearance of Laseg's symptom originate from this disease. In addition to him, the patient also has other symptoms: Neri - the connection between the flexion of the head and back pain, Bahretev-Fierstein - the affected limb begins to ache while raising a healthy leg. The patient is prescribed such medicines:

1. Nonsteroid drugs that have anti-inflammatory and analgesic effects: Ketoprofen, Diclofenac, Flurbiprofen, Indomethacin, etc. They help to quickly eliminate the main symptom of radiculitis - pain.
2. The muscle relaxants arrest spasms of skeletal muscles. Despite many side effects, they are able to eliminate the compression of nerve fibers. For example, "Tubokurarin", "Doksakuriy", "Rapakuroniy". By the way, they are prescribed for the treatment of osteoporosis.

In addition, to eliminate Lasega symptom with radiculitis, the patient is prescribed narcotic analgesics. But this is only in critical cases, when the pain is simply unbearable and not removed by other drugs. The patient is also recommended to drink antidepressants and vitamins.

Prevention

To prevent Lacega symptom, as well as the development of dangerous diseases associated with it, it is possible to carry out preventive measures. They also protect the person from osteochondrosis and radiculitis. And even if the patient is already sick, they serve as an excellent supplement to drug therapy. Among them there are such procedures:

• Gymnastics. If physical loads are given at least half an hour a day, you can achieve an increase in bone mass by 5%.
• Massage. It improves blood circulation in muscles.
• Sunbathing. Ensure the intake of vitamin D in the body, without which the absorption of calcium would be impossible.

It is also recommended to abandon bad habits, which since ancient times are faithful companions of numerous diseases. And also learn how to eat right. Refusal of fatty, smoked, fried, canned food will only benefit the body. If in addition to balance the use of proteins, fats, carbohydrates and enrich the diet with vitamins, fiber and other useful substances, you can achieve full-fledged health, good physical shape, youth and beauty.
