Various disorders of the functions of the nervous plexuses are called flexopathies. . Plexus is a nerve plexus, which, if you draw an analogy with the house, resemble a junction box with electrical wires coming from it to different parts of the house. Such nerve plexuses are original distributors of the nervous system, and nerve damage in them causes various disturbances in the work of the extremities innervated by these nerves.
In the neck area is located one of the main plexuses of the body - the brachial plexus. From it, nerves go to the hands. Another major plexus is located in the lower back - the lumbar and sacral plexus, whose cat nerves move to the legs and pelvis.
If the function of the brachial plexus is disturbed, a person may feel pain and weakness in the hand. In this case, weakness can capture both the entire arm and part of the hand - for example, the biceps or forearm area. If the cause of the disruption of the plexus function is in an autoimmune disease, the hand may soon lose strength (within one day or a week), recovering very slowly - for several months. Also, recovery will be slow after some accident, and some serious injuries can cause irreversible muscle weakness.
When the function of the lumbosacral plexus is disturbed, there are pains in the lower back and leg, weakness in the entire leg or in its part. And the weakness affects only the muscles of the calf or foot, but in some cases there is paralysis of the entire leg. In such cases, recovery depends on the original cause of the condition. If plexus damage occurs as a result of an autoimmune condition, then plexopathy will be eliminated for several months.
So, the symptoms are: numbness, muscle weakness, tingling, weakness or paralysis of the legs and weakness of one or both hands.
Damage to the nerve plexus is often the result of an autoimmune reaction, when the antibodies formed in the body attack their own tissues. So, most likely, there is a sudden disruption of the function of the brachial plexus - acute brachial plexitis.
But more often plexopathies arise as a result of any physical impact or in malignant neoplasms. For example, a hand injury in an accident leads to damage to the brachial plexus, and a fall leads to damage to the lumbar or sacral plexus. Growing in the upper parts of the lungs, a malignant tumor can spread to the brachial plexus and destroy it, while a tumor of the bladder, small intestine or prostate can affect the lumbar or sacral plexus.
Treatment of plexopatia
The methods of treatment depend on the causes of the damage. A malignant tumor located near the plexus is treated with radiation therapy or chemotherapy, or surgically removed.
If the cause of plexopathies is an autoimmune reaction, corticosteroids are prescribed, although the benefits of their use are not proven.
For the treatment of acute plexopathy caused by trauma, only time is needed and sometimes neurosurgical treatment.
