The human joint is the articulation of bones. Since all its components are neatly smoothed and additionally enveloped by a special synovial fluid, no sounds are heard during movement. Why sometimes joints begin to crackle? There are several main reasons. Some of them are completely harmless and cured by themselves. But sometimes the crunch arises from serious diseases that require close professional attention.
Why crunches joints - the main reasons
As a rule, the appearance of a crunch in one or another joint during movement makes you tense. Especially if strange sounds are constantly being harassed. But even in this case, the crunch does not always signal a serious illness.
Here are the main reasons why the joints on the legs, in the pelvis, hands can crackle:
- The most innocuous explanation of the alarming sound is the accumulation of gases. In the liquid, which acts as lubricant joints, in addition to special substances, include carbon dioxide, nitrogen and oxygen. During movement, when the overstretch of the joint bag is observed, the gas moves and collects into rather large bubbles. As soon as the bones are in place, the formed balls burst, producing a characteristic sound.
- Another reason why joints can crunch in the knees and on the body is inflammation. In this case, the cartilage loses its natural smoothness. The rough surface, in turn, starts crunching.
- Sometimes with awkward movements, the tendons change position. Not too loud a click - an alert that everything fell into place.
- In some people, the joints crack because of the presence of a foreign bone-cartilaginous body in them. The latter, as a rule, appear after injuries or because of some diseases. Neoplasms freely move around the joint. The crunch is heard when they prevent the bones from moving normally. Sometimes it is accompanied by pain or even blockade.
- Why can still the ankle, shoulder and knee joints crunch because of its hypermobility. Clinking sounds only occur when a person does some kind of exercises very actively and with too much amplitude.
- A crunch in arthrosis testifies to the so-called erasure of the joint. This is a degenerative change in the cartilaginous tissue, because of which it loses its strength. In the later stages of the disease, the cartilage becomes hardly noticeable, and osteophyte spines form on the joint surfaces. They also contribute to the appearance of a crunch.
- In order not to wonder why the joints crunch after the gym, all exercises during the exercises need to be done carefully. And the training complex should be coordinated with a specialist. Otherwise, minor, but very unpleasant, injuries are possible.
- Suffer from the crunch is and those people who have congenital increased muscle flexibility .
Why do crunches of joints in a child?
Especially frightening seems to be a crunch in the joints of a child. Parents, after hearing it, immediately run to traumatologists. But these actions are not always justified. In fact, strange clicking sounds in most cases arise only because of the immaturity of the children's connective-muscular apparatus. After the completion of the formation of the musculoskeletal system, the crunch usually disappears.
If the problem becomes too intrusive, an experienced specialist will help to select the necessary set of exercises to eliminate her, and also prescribe a suitable diet.
