SURGICAL DISEASES, TRAUMATOLOGY, ORTHOPEDICS, UROLOGY : ARTICULAR MOUSE (MUS ARTICULARIS) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Pathological changes in the joint: inflammation, arthritis, osteochondritis, entail the rejection of particles capsules, the host bone and cartilage character. In traumatic injuries with subsequent hemorrhage into the joint occurs the precipitation of fibrin. clots which may remain in the cavity of the joint is free; the separated small bone particles, particles capsules, cartilage, freely moving inside the joint, also form a joint mouse.
Symptoms and recognition. Periodic infringement mouse cause sharp pain and the impossibility of movement in the joint. The diagnosis is confirmed radiographically only in cases where joint mice are impervious to x-rays.
For. Painful condition affects over a long period after injury or acute inflammatory process. Small size articulate mouse sometimes can gradually disappear. Larger mouse frequently violated in the joint, disabling it and causing a sharp pain. After some careful movement in the joint is a state passes (repositioning of the articular mouse) and the function of the joint is restored; the oft-repeated infringement of joint mice, long-term irritation of the joint cause of the effusion in the joint. Repeated inflammation leads to chronic synovitis, chronic and deforming arthritis.
Cm. Diseases of the organs of movement Arthritis deformans. With frequent infringements of the articular mouse recommended surgery (removal of the articular mouse).
