What is denervation?

What Does denervation Mean

Before entering fully into the meaning of the term denervation, we are going to proceed to discover its etymological origin. In this case, we can point out that it is a word that derives from Latin, it is exactly the result of the union of these Latin components:

-The prefix “des-”, which is used to indicate “negation”.

-The particle “en”, which means “inwards”.

-The little noun “nervium”, which is synonymous with “nerve”.

-The suffix “-cion”, which is used to indicate “action and effect”.

The act that the nervous system develops on the functions of the organs is called innervation . When a nerve innervates some part of the body , it reaches it. The idea of denervation refers to the loss of innervation in a certain structure of the organism.
Denervation, therefore, may imply that a muscle loses innervation due to injury or other disorder. If a nerve pathway is cut or if its transmission of impulses is interrupted by a drug, it results from denervation.

One of the consequences of muscle denervation is atrophy . When the muscle is no longer innervated, it does not receive the signals it needs to maintain its normal size. Thus begins to develop muscle atrophy, which implies a decrease in its mass.
In case denervation is suspended and innervation is restored, the muscle can regain its functions . On the other hand, if the denervation is maintained over time , a few months later the muscle fibers begin to degenerate. Therefore, a sustained denervation over time can become irreversible because the muscle, after a certain moment, is no longer in a position to regain normal function.
Sometimes denervation is done on purpose to relieve pain . In this framework, we can speak of radiofrequency denervation , which seeks to deactivate the nerve that causes the ailment.
A clear example of how denervation can be used intentionally to cope with a chronic condition is in the case of chronic low back pain. In particular, it is considered that the radiofrequency to achieve that can achieve what is pain relief. Of course, it must be borne in mind that it is a solution for which there is still no medical evidence that it manages to significantly improve the situation.
Radiofrequency denervation has another series of interesting aspects that are worth knowing:

-It is also called rhizotomy or rhizolysis.

-It is recommended, above all, by what are units that are in charge of pain treatment.

-It is used mainly for ailments that affect the lower part of the back or the neck. We are referring, for example, to back pain and neck pain, among others.

Although denervation procedures are often used to treat chronic low back pain, it is important to note that their safety and efficacy are often questioned by some physicians.
