Crunch in joints of
Presently pathology of connecting fabric rivets attention of researchers of different medical specialties.
Relevance of this problem causes a huge number of pathological manifestations which cornerstone changes from connecting fabric are. Also existence of such widespread phenomenon as a crunch in joints depends on features of its structure.
The matter is that the reason of a crunch of joints is not unambiguous. In - the first, articulate sheaves stretch that allows a joint to do more voluminous movements which are going beyond its anatomic opportunities. As a result elements of the adjoining cartilaginous surfaces can publish characteristic clicks. Such “tensile properties“ of articulate sheaves arise as considers most of experts, as a result of structural change of one of soyedinitelnotkanny proteins - collagen. As a result of it collagen becomes less strong, but also is more elastic and gains ability to partial deformation. This factor has a hereditary origin, however the mechanism of development of this soyedinitelnotkanny inferiority still remains unknown.
decrease in sekretiruyushchy function of the circumarticular bag protecting a joint from gaps and other mechanical damages is the Second reason of a crunch of joints. The matter is that the articulate bag, besides protective function, is urged to provide sufficient sliding of the jointed surfaces of bone elements from each other. For this purpose in a cavity of a joint so-called sinovialny liquid which value can be compared to greasing of the rubbing details in some mechanical unit sekretirutsya: thanks to sinovialny liquid the friction is minimized that guarantees reliable and painless work of a joint. The lack of sinovialny liquid worsens sliding and causes joint “poskripyvaniye“, precisely as badly greased wheel would creak.
situations when sinovialny liquid is emitted in enough Happen, however its quality suffers as a result of shortage defined components. Such elements are a glycosamine and hondroitin - the substances produced by cartilaginous tissue of joints and the having important physiological value. So, hondroitin reduces activity of substances which are capable to destroy cartilaginous layers of a joint, stimulates restoration of cartilaginous tissue, slows down processes of its natural “wear“ and improves depreciation properties of a cartilage. The glycosamine serves as a necessary construction component of a hondroitin and is a part of substances, other, not less important for a joint. Thus, deficiency of a hondroitin and glycosamine is the third reason which can cause undesirable “noise“ effect in joints.
What means a crunch in joints? How to react to it? If the crunch in joints is followed by morbidity, it is necessary to see a doctor immediately: it is available the main clinical signs of inflammatory or dystrophic changes. However anyway, even in the absence of morbidity, the crunch means that such joint is more inclined to developing of various diseases and is less steady against external mechanical loadings. Therefore such “crash“ can demonstrate that arthritis or arthrosis already not far off! The risk group includes generally the people leading an inactive life, i.e. those who practically do not train the articulate the device, and also elderly. However and excessive activity with the raised physical overworks can lead to joint stretching, especially, too if to it there was a genetic predisposition. That is why among athletes there are a lot of injured.as
scientists of the whole world work On problems of a disease of joints today. One of the most modern directions in drug treatment of these diseases is use of so-called hondroprotektor, i.e. the substances protecting cartilages and all joint in general from the mechanical overloads and promoting their restoration.
