Diagnosis and treatment of synovial chondromatosis


- Diagnosis and treatment of synovial chondromatosis HU Jian Shan Wong far Orthopedic Hospital of Guizhou Province 558000 Qiannan synovial chondromatosis is a rare synovial disease, may also occur in synovium and tendon sheath, synovial hyperplasia and connective tissue the formation of cartilage metaplasia bodies are the main features of the disease. Often calcified cartilage or ossification bodies, also known as measures membrane osteochondroma. Are summarized below: 1 Incidence of synovial chondromatosis of the low incidence reported in China since 1952 have been over 100 cases, more men than women, age generally 3O a 50 years old. Often involving the joints,[link widoczny dla zalogowanych], the knee more common, but also may invade the hip, shoulder, ankle. 2 cause has not been determined are the following theory. Theory that the more common lower extremity injuries due to solid weight-bearing activity and lower extremity joints being squeezed due to synovial suffered fresh injury,[link widoczny dla zalogowanych], some patients may be forced to seek a clear history of trauma, malformation of developmental theory that the synovial cells in the nest tube, adult differentiate into cartilage, synovial membrane was also considered to be benign, but it was denied. No cartilage cells in the normal synovial membrane, in recent years that some factors in the stimulation of cartilage and synovial connective tissue under the cortical cell metaplasia. McCarehy synovium by electron microscopy and found that bone nodules around the transition zone is between the cartilage cells and fibroblasts differentiate between the cells. Synovial chondromatosis of collagen in patients with tumors composed of cartilage metaplasia theory of support, some people advocate the use of synovial chondromatosis of the disease name, get rid of the name of synovial osteochondromatosis, c to highlight the start of the disease is the formation of synovial metaplasia cartilage, and ossification of cartilage Buyi Ding = 3 pathological lesions of the disease mainly occurred in the synovium, synovial lesions of congestion, thickening, villous hyperplasia, multiple white nodules affect the performance of processes, can be linked into a film. Microscope angiogenesis. Lymphocyte aggregation, synovial surface cells and fibrous tissue proliferation of synovial fibroblast cell metaplasia into cartilage cells, the formation of calcification or ossification of cartilage, such as different time Bu body. Prominent bodies mature cartilage surface of the formation of cartilage nodules or pedicle hanging on the joint cavity. City break off into intra-articular loose bodies. Free body smooth, white, yellow, grain sizes of more than 103 pieces of high Diego, as big as corn,[link widoczny dla zalogowanych], ranging from as small as a grain of rice. 4, Summer X-ray findings of clinical clinical manifestations of this disease and arthritis as chronic Ge and the performance of intra-articular loose body the same, mainly intermittent joint pain, swelling, function by the storm. Joint activities within the sense of sound or friction. Section change the lock on a small number of patients, some of the most active palpable mass x-ray films to see whether the decision bodies of cartilage calcification and ossification of the extent of their early when the bodies are not calcium. x ray can not show the typical x-ray showed multiple joint cavity round or oval opaque shadows. Varying degrees of uneven density. Was in general, weak. Every week, dense, relatively uniform shade too small for calcification or ossification of the cartilage bone bodies. Articular surface and joint space generally remain normal, no bone destruction, osteoporosis, in the synovial Department, spotted calcification shadows. Course of the elderly may be secondary to degeneration of bone,[link widoczny dla zalogowanych], a small number of bone erosion. 5 young patients diagnosed with chronic arthritis. Non-suppurative inflammation of the performance of the Results table above symptoms, signs and x-ray can often make the diagnosis. positive x-ray films are important for diagnosis. But the x-ray film negative does not rule out the disease, if necessary, can be used for intra-articular joint endoscopic imaging or plant investigation. Current definition of the disease and pathological processes there are different views, TfaffemcIvor intra-articular loose bodies and put forward. To see the proliferation of synovial villi and cartilage bodies. Such as the formation in order to make the diagnosis. Have said: There are four on the intra-articular loose bodies can be diagnosed based disease. 6 Differential diagnosis of intra-articular loose bodies and confusion of this disease diseases: bone and joint diseases, the disease had relatively large loose body formation, the number of small, high density, the bone structure. The pathological basis of bone lesions and articular surface damage, x-ray film with joint space and bone changes, pigmentation, hair-chien arthritis synovitis with the performance increase can be palpable villonodular tissue formation package block. Ying, but not the cartilage group, l Section liquid water chestnut brown, bone destruction often 7 to surgery to treat the disease better, the recurrence rate is low, there are reports from the birds who can. Without treatment, friction free body compression will result in mechanical damage to the joints, followed by the development of osteoarthritis. Supine position surgery. Intra-articular loose bodies removed to eliminate symptoms and prevent secondary joint lesions caused by loose bodies,[link widoczny dla zalogowanych], such as membrane formation of limited joint fossa. Asymptomatic or mild symptoms, surgery may be temporarily free of the disease more than the number. Small size. Difficult to completely eliminate a small number of loose bodies left after surgery, there are signs and symptoms may re-operation. However, we advocate careful, patient and surgery removed all the better 1 (16
