Arthrosis ( deforming arthrosis, deforming osteoarthritis )
Occupational Diseases / / August 12, 2017
Osteoarthritis is a chronic joint disease, in which the degenerative-dystrophic changes combined with hyperplastic.
In cases where the process captures mostly cartilage, talk about deforming arthrosis, with the involvement of bone - about osteoarthritis.
Deforming osteoarthritis occurs as the outcome of a single intra-articular injuries or severe infectious arthritis, but most often - as a result of a long professional surge.
Long monotonous forced posture, tremors and shaking of the joints or parts of the joint leads to a decrease in the elasticity of cartilage, a violation of his power, degeneration, and sometimes to focal necrosis.The relationship between occupational stress and the development of osteoarthritis deforming confirmed the dominant lesion precisely those joints that are subjected to load predominantly in a number of professions.Phenomena deforming osteoarthritis is quite often observed in the main joint of the thumb and other small joints of the hand have shoemakers, carpenters, assem
Professional deforming osteoarthritis develops primarily chronically and in contrast to the age-related changes observed in young and middle aged.With age, the frequency of the disease increases.
Deforming osteoarthritis flows slowly and for a long time itself does not show.At first there are only sensations of awkwardness and embarrassment of some movements.The disease progresses gradually, aching, persistent distortion and crunch when driving.To diagnose the disease X-ray examination is important, but the initial, early changes in cartilage detected radiographically ie labor.With the involvement in the process of bone X-ray diagnosis is not difficult.During this period, characterized by joint space narrowing as a result of the destruction of cartilage and convergence bones forming the joint.However, the joint space, though narrowed, always saved, and in contrast to inflammatory diseases of the joints - arthritis - there is never a bone ankylosis.The head and glenoid cavity flatten, and at the free edges of the articular surfaces of various shapes appear razrascheniya bone.Articular surface waviness sometimes eaten.In some cases, handbags volvulus can be detected and isolated intraarticular free bodies.If the movement in the joint retained, the regional osteoporosis and bone atrophy are usually absent.
important feature of the occupational origin of the deforming osteoarthritis unlike involutive changes is much greater loss of loaded when the joints in comparison with other, in particular with joints unloaded opposite side.Therefore, X-ray of the other, healthy, hand contributes to a correct assessment of osteo-articular changes and establish their relationship with the patient's profession.
Physio-Mechano and spa.Complete cure is not achieved;the disease gradually but inexorably progresses, which is typical for deforming osteoarthritis.
disability When expressed osteoarthritis occurring with limited function of joints, especially the tendency to progression is contraindicated in work related to the load on the joints.
Preventing such damage is based on the professional compliance measures that eliminate excessive overloading joints.
