Deforming arthritis - a disease thatcharacterized by degenerative-dystrophic changes in joints. Depending on the cause and nature of the changes to the primary osteoarthritis is the primary and secondary. Both in one and in another case - and this neighborhood synovitis of osteoarthritis, with the only difference that the primary arthritis synovial inflammation develops later, and at the secondary - precedes the phenomena of cartilage degeneration.
Primary osteoarthritis of the hands and feet occurs asdegeneration of articular cartilage, leading to a decrease in its ability to withstand the load. Microtrauma and subsequent destruction of cartilage is accompanied by lesions of the epiphyses of bones and formation of osteophytes, traumatic joint synovial membrane. Since then, the primary arthrosis is accompanied by synovitis, aggravating degeneration of cartilage.
Symptoms of secondary osteoarthritis often growfrom arthritis clinic. In this case, synovitis usually preceded by degeneration of cartilage, it is the root cause of the violation of his power and the rapid subsequent destruction. In the presence of intra-articular fractures, disorders congruence of articular surfaces deforming osteoarthritis diagnosed immediately at 2 degrees, bypassing the initial stage of disease, and lead to joint immobilization for 4-5 months.
The clinic osteoarthritis is divided into three stages, characterized by typical for each stage of development of the disease subjective and objective manifestations, radiological signs.
Deforming osteoarthritis 1 degree
External manifestations of primary osteoarthritis is quitescarce, although a detailed examination at this stage can detect signs of degeneration of articular cartilage. There fatigue Of course, some muscle stiffness after a long rest. At the 1 st degree of deforming osteoarthritis symptom limitation of joint movement - a rare phenomenon, as well as joint pain.
Deforming osteoarthritis develops unnoticed. At 1 degree disorders, patients do not usually go to the doctor, only if the primary disease. For arthritis, proclaiming the predominance in the clinical picture of arthrosis phenomena synovitis, at the very beginning of the disease there is pain and swelling of the joints, which can not go unnoticed.
Osteoarthritis, the symptoms of which are rooted injoint injury, initially manifested by pain and limitation of movement, as a violation of the integrity of the cartilage. Pieces of cartilage wander into the joint cavity, irritating the synovial membrane, causing synovitis and its accompanying pain. If the distance between the fragments of cartilage than 2 mm, then the healing comes with the formation of callus in violation of the congruence of the articular surfaces, acting as a factor that reduces the depreciation characteristics of cartilage and leads to damage to the bone.
Radiographic signs of deformingosteoarthritis 1 degree - a joint space narrowing and sclerosis of light, ie the seal of bone tissue in the subchondral plate area. If posttraumatic arthrosis in cartilage fracture callus area is rendered, but it is rather a sign of deforming arthrosis of 2 degrees.
Deforming arthrosis of 2 degrees
In the second stage of development of osteoarthritischaracterized by symptoms of increasing restrictions of movement. Wandering inside the cavity of the joint fragments of ossified cartilage cause the appearance of a crunch in the joint and its blockade.
Deforming osteoarthritis in the 2nd stage is characterized by deformation of the joint, limiting his mobility due to contractures and muscle wasting, as well as the appearance of lameness.
Joint pain is most pronounced "at the start." Her appearance is due the fact that the first load falls on a modified, "painful" part of the cartilage. When the cartilage in the motion "adapts" load and redistributed evenly over its entire surface, the pain disappears. By the end of the day, when the accumulated "fatigue" of joint tissues, pain appear again, but at this stage of osteoarthritis, they still held after a long rest, can not be said about the next stage of development of the disease.
For osteoarthritis in the second stage of change is typicalperiods of pain amplification periods of its complete disappearance. This is due to the layering in the symptoms of osteoarthritis clinical inflammation of the synovial membrane, flowing waves.
Radiological second stage of osteoarthritis is expressed in the appearance of osteophytes, a sharp narrowing of the joint space and subchondral sclerosis zone epiphyseal bone.
Deforming arthrosis grade 3
The third degree of osteoarthritis is characterized byconstant pain, complete immobilization of the joint while maintaining the ability to passive low-amplitude movements. The patient is not able to move independently and have to use crutches or a cane.
On radiographs: the complete absence of joint space, the deformation of the articular surfaces, multiple cysts in the subchondral bone epiphysis zones
