[ Pathogenesis ] ¨d¨d¨d is unclear, after at present thinks is 滑膜 stimulates the wound or the inflammation the reactivity proliferation forms. 滑膜 the cell has the metaplasia forms 软骨细胞, in 滑膜 inside deposits, and has more blood vessels long enters, turns 骨化 the center, the unceasing growth, assumes 息肉 the shape long peduncle shape and with 滑膜 is connected, increases along with it falls off forms in the joint cavity drifts away the body. After loses the blood supply, the pe**hery cartilage just like the package of shell, depends upon the bone fluid may continue to survive grows, forms the comparatively greatly more lumps body. This gets sick because encroaches upon the joint, may cause the joint ache, swelling, causes the function barrier, therefore should 早期诊断, the early surgery treat. This time small bleeds as a result of the wound few, therefore the adhesion and the scar are few. Is advantageous the joint function restoration and the ache symptom vanishes after the technique. In the technique should the strict aseptic operation, on the strict blood, avoid pe**hery organizing once more to damage, 彻 底情 drifts away the body except the joint in and the sickness stove organization, guards against recurs. The infection, after the technique the adhesion and 脱位, affects the function restoration.
[ Pathology change ] ¨d¨d¨d for 滑膜 the hyperemia, the accumulation, 绒毛 the multiplication, the performance spreads the size does not wait 结节, the small like millet grain, the big diameter may reach above Icm. 结节 the nature is hard, assumes the white or half transparency, the partner has assumes the lavender; 结节 with 滑膜 is connected by the extravagant bottom or the narrow peduncle, either falls off into the joint cavity, either locates 滑膜 in the nei**orhood of the pouch and the joint 腱鞘 inside, becomes drifts away the body. Its shape respectively different, is in the majority by the circular or the egg circular. The section plane is the cartilage, inside may 钙化 or 骨化, it 中心部 may have the fat marrow. Under the mirror obviously the blood vessel proliferation, the lymphocyte gathers, 滑膜 the surface layer cell and the fiber structure proliferation, sometimes obviously Large expanse of becomes the ciliary cell metaplasia for 软骨细胞, forms 软骨小体 and 钙化 and 骨化 and so on the different stage. M lie ram divides into through the pathology shape observation this sickness three stages: (1) Acute time: 滑膜 the change is obvious, but in the joint not drifts away the body; (2) 中间期. The transition 滑膜 pathological change merge 滑膜 骨软骨瘤 and drifts away the body; (3) 骨膜 the pathological change terminates the time: 滑膜 restores normal or only has the mild inflammation, many drift away the body formation.
[ 临床表现 ] ¨d¨d¨d drifts away the body performance with in the common chronic arthritis and the joint is same. But the course of an illness is slow. The most patients early time may do not have the symptom, continues several months, several years, after even several ten years, exhaust oneself the joint gradually have the ache, swelling, the function receive limit, when activity in the joint may have the foreign matter feeling and twist locks the phenomenon, sometimes may the steel and 活动性 the package of block.
[ Good sends crowd, spot ] - may know by the above case of illness, this case of illness sends much to the **, are many is the female. Nearly all arises for the big joint, knee joint arises accounts for 65%, the hip joint arises accounts for 28%, the shoulder joint also has arises.
[ Typical image performance ] x ¨D change has the many circulars, the egg circular opaque shadow for the joint spot, the density may assume the uniform nature advances, also may the pe**heral density be high. But the center is translucent. The joint gap and 关节面 the general maintenance is normal. Later period the patient obviously 关节面 edge ossein proliferation draws back the change in sexuality. X even piece approximately has 1 / 3 patients does not have 钙化 or 骨化 the change, if makes the gasification radiography, obviously many negative shadows.
The CT- - performance roughly is similar to the even piece institute sees, only is obviously drifts away from the cross section the body and the joint constitution bone dividing line is clear, the joint constitution bone does not have the destruction.
MRI - MRT1WI, T2WI and FSEIR is all consistent with the thi**one central yellow marrow organization signal, the sickness stove central obviously selects the shape T1 low signal and the FSEIR high signal should consider for not 骨化 the cartilage organization. |
