bony plate

Results No pathological change was noticed in the control group. Among the 96 cases of SpA, pathological changes were found in 76 cases, including bone marrow inflammation, pannus formation, subchondral bony plate destruction, cartilage degeneration/ erosion, synovitis, and enthesitis.

结果76例SpA的SIJ存在炎症表现，包括骨髓炎、血管翳形成和炎性细胞浸润，软骨下骨板破坏，软骨变性、破坏，滑膜炎，附着点炎等。

In the advanced sacroiliitis ( CT ⅳ degree), destruction and calcification of cartilage and subchondral bony plate were the major feature.

CTⅣ级SIJ炎的病理改变则以软骨下骨板破坏，大量死骨形成，钙盐沉着为主要特点。

Outcome of4 patients demonstrates that treatment of congenital pseudarthrosis of the tibia with armor plate and xenogenic bony plate is a reliable treatment.

假关节切除植骨钢板结合骨板内固定治疗先天性胫骨假关节效果好，可以达到骨折的牢固固定的目的。

In the CT ⅱ and ⅲ degree sacroiliitis, marked degeneration and fibrosis of cartilage, inflammatory cell infiltration, pannus formation and subchondral bony plate destruction were increasingly prominent.

CTⅡ～Ⅲ级SIJ炎病理变化主要为软骨严重变性、破坏，血管翳形成，大量炎症细胞浸润，软骨下骨板破坏；

Conclusion Synovitis, including hyperplasia of lining cell and the infiltration of inflammatory cell in loose connective tissue, and local cartilage degeneration and inflammatory cell infiltration, and destruction of subchondral bony plate are the early changes identified in sacroiliitis.

结论滑膜衬里细胞肥大增生、疏松结缔组织炎症细胞浸润等滑膜炎表现，局灶性软骨基质减少、变性、纤维化和软骨下骨板炎症细胞浸润、破坏，是早期SIJ炎的病理特点；

Sacroiliitis probably initiated with bone marrow inflammation, followed by pannus formation, subchondral bony plate destruction, and cartilage degeneration/ erosion, eventually leading to fibrosis, ossification and joint fusion.

SIJ炎可能自骨髓开始，继而血管翳形成，软骨下骨板破坏，软骨变性、破坏，最后纤维化、骨化而导致关节融合。
