Deforming osteoarthritis is one of the most common diseases of the joints, characterized by degenerative dystrophic changes in cartilage tissue and bone epiphyse. What are the reasons and hidden from eyes the stages of the development of the disease?

Deforming Osteoarthrosis — One of the most common diseases of the joints, they suffer from 5% of the population of the globe, a third of the visitors of the Orthopedic Cabinets Polyclinic — Patients with arthrosis. Disease treatment is complex, long, expensive. Without a competent approach after 10-11 years old, Arthrosis and the accompanying contracture of the joints invariably become the cause of disabilities.
Deforming arthrosis — This is a disease of the joints and bones. Its beginning signs the dystrophy of the articular cartilage with the subsequent degenerative-dystrophic changes in the epiphyuses of bones forming the articulation. Regardless of the reasons, osteoarthritis — The disease is chronic, progressive, leading to complete immobilization of the joint.
The correct name of the disease «Deforming Osteoarthrosis» or «Deforming arthrosis», but not «Arthrosis Justov». Causes: Word itself «Arthrosis» already implies bone articulation and word disease «Joints» is too much.
Deforming osteoarthritis: reasons
The causes of the development of deforming osteoarthrosis are diverse and, in any case, the initial stage of development — This is arthrosis, expressed by damage to the intra-articular cartilage, and the factors causing these damage may be different:
- unfavorable working conditions with high burden on the joints;
- Sustav innervation disorders, accompanied by the restructuring of circulation and cartilage dystrophy;
- neurohumoral and endocrine changes in the body that violates the nutrition of the tissue of the joint, causing the phenomena of initial arthrosis, and then the progression of the disease;
- enzymatic disorders leading to metabolic disorder in the field of cartilage and the development of deforming arthrosis;
- immune shifts and autoimmune processes accompanied by damage to the cartilage connective tissue;
- Vascular factors, one way or another affecting the state of hyaline articular cartilage.
All of these factors can put the start of arthrosis, initiate damage to the articular cartilage.
In an ordinary understanding of etiology and pathogenesis osteoarthrosis, the causes of its occurrence look like this:
- regular microtraums of articular cartilage as a result of lifting weights, sharp movements, long walking, repeated monotonous movements;
- complicated during intra-articular and occasional bone fractures;
- arthritis;
- Congenital inferiority of joints, xondrodstrophy, joint dysplasia, accompanied by both original cartilaginous tissue defects and its injuries;
- Aseptic necrosis of bone epiphysis, arthrosis developing at the last stages of the disease.
Pathogenesis of deforming arthrome or osteoarthritis from the inside
Initial arthrosis — This is a state of dystrophy of the artician cartilage.
To understand how the so-called is developing «Arthrosis Justov», The cause of which lies not in the background diseases of the joints or their injuries, and in the field of the primary power disorders of the cartilage tissue, you must first figure out what kind of hyaline cartilage and where it draws the necessary substances for its «existence».
Hyaline articular cartilage, which is an elastic sponge, a synovial shell, covering the surface of the joint from the inside, and the articular liquid filling the body cavity, — This is one system called «articular synovial environment». Due to the synovial fluid penetrating the cartilage tissue when it is compressed, the cartilage is powering from the inside. From the bone on which «lying» cartilage, there are substances from blood vessels of subchondral record. Violation of the synovial fluid exchange and change in blood circulation in the epiphyse bones leads to «Fasting» cartilage. Dystrophic changes are launched osteoarthritis, act as the causes of subsequent degenerative processes.
In conditions of insufficient nutrition, cartilage lose their properties and the ability to resist the loads. The phenomena of arthrosis develop, the bones are deprived of protection, and the subchondral plate begins to test shocks, leading to a violation of blood circulation in it and the subsequent aggravation of dystrophy of cartilage tissue.
Chrying more and more «starving», It becomes fragile, cracks appear on its surface, small pieces irritating the synovial shell, provoking synovitis and a violation of the metabolism of synovial fluid. Cartilage, deprived of another serving of nutrients, thinning and erased, opening the surface of the epiphysis bones.
On such injuries, the bone reacts to the accelerated construction of the bone substance towards the articular slit, osteophytes are formed, mechanically irritating synovial shell, exacerbating synotes and causing the appearance of stiffness of movements. So progresses Arthrosis, «Bone», which should not be present in the custody of the joint normally, it becomes more and more. They begin to block the movements of the joint, «unite», germinate with connective tissue and finally completely deprived of the joint ability to move. There is a contracture of the joint and the patient becomes disabled.
