Arthrosis - a disease of the joints, which is considered associated with dystrophic and slow the destruction of cartilage within the joint. When Arthrosis over a long time there are changes, the restructuring of the articular ends of bones, are inflammation and degeneration of periarticular tissues. In such a concept as "arthrosis" is also still not a very large group of joint disease degenerative inflammatory nature, which have different causes and similar mechanisms of their development.

Arthrosis is the most common joint disease in the world, according to statistics, in varying degrees, suffer from Arthrosis to 80% of the world population. Lesions of this type are quite common, and are in third place, after cancer and cardiovascular diseases.

The probability of developing Arthrosis increases with age many times. Disease equally affects both men and women, is the only exception interphalangeal joint arthrosis, since it is most often seen in women. Arthrosis catches people of working age - between 30 years and the number of cases is stable and has been steadily increasing every year.

Arthrosis develops due to metabolic disorders in the joint, which in turn leads to the fact that cartilage begin to lose their elasticity. This can contribute to the total or partial loss of proteoglycans from the cartilage, this happens usually due to the rather deep cracks in the cartilage. Losing proteoglycans can occur for another reason: because of the failure of their joint production cells.

As experts say, the reasons for which may begin to break down articular cartilage may be metabolic, hormonal disorders, decreased blood flow joint, hereditary factors, advanced age, injuries and diseases such as rheumatoid arthritis and even psoriasis. Still, the most common cause of arthrosis is not normalized stress on the joints, while the cartilage can not resist it.

Symptoms of Arthrosis

The symptom of arthrosis is pain when the load on the joint, which subsides when the joint is at rest; reduction in joint mobility, crunch, feeling the muscle tension in the joint. Periodically arthrosis affected joint can swell and deform over time.

Consider the following four major groups of symptoms of arthrosis:

Pain. The presence of pain - this is the first sign of arthrosis. We can assume that in any of their faults occur such feelings, but in osteoarthritis pain has some peculiarities. Firstly, it is the occurrence of sharp pain or significant discomfort at the time of movement. It is localized at the location where the diseased joint is situated. When a person stops traffic and enters into a state of dormancy - the pain goes away.

At night the discomfort a person feels little, except during the upheavals of the trunk, finding the optimal position - the patient goes to sleep quietly. There are pain while resting only at the stage of progression of the disease, they have a certain similarity to the dental chamber, when a person can not sleep. Manifests itself towards morning - to 5 hours.

So, at the beginning of the pain there is little, it can be felt only when loading or palpation, eventually amplified human suffering, and the joint will require more rest periods. Then life at all turns into a torture - hyaline cartilage thins, the bone is exposed, it begins to grow osteophytes. Sharp pains torment almost continually, even more amplified in bad weather and a full moon.

Crunch. No less revealing symptom of osteoarthritis is the presence of a crunch. He becomes audible due to the fact that the bones in the joint rotation of the softness is reduced, they rub against each other, resulting in a distinctive sound and there. The crunch can be heard in other diseases, and even when healthy joints. But it is distinguished by its arthritic crunch "dry" sound. The more the disease progresses, the brighter the sound. Moreover, if the crunch is heard, it will feel the pain. That is what makes it possible to distinguish the sound coming from joints with osteoarthritis of the usual harmless a Clicking.

Decreased mobility in the joints - is another characteristic symptom of osteoarthritis. At the initial stage, this phenomenon does not disturb the patient, but with the progression of osteoarthritis, bone neoplasms germination causes spazmiruyutsya muscles and joint space disappears almost completely. This is the cause of immobility of limbs in the site of the lesion.

The deformation of the joint. His modification is caused by the fact that on the surface of the bones grow osteophytes and synovial fluid arrives. Although deformation - this is one of the most recent symptoms when struck joint arthrosis already largely.

The disease is characterized by the acute stage and remission. This makes it difficult to self-diagnose osteoarthritis, relying only on their own feelings. Therefore it is necessary to ask for clarification of the diagnosis to the doctor.

During the X - ray studies, it will be able to find the following features to help you determine the degree of progression of the disease:

Stage 1 is characterized in that no osteophytes, joint space may be somewhat narrowed.

In stage 2 there is a suspicion of a slight narrowing of the gap, osteophytes have formed.

In stage 3 the gap narrowing clearly visible, there are multiple osteophytes, the joint starts to deform.

Stage 4 is characterized by the almost complete absence of joint space, multiple osteophytes, and significant deformation.
