Erosive osteoarthritis (EOA) is a progressive disorder affecting the interphalangeal joints of the hands. Severe synovitis is superimposed on the typical changes seen in conventional interphalangeal osteoarthritis (OA), which includes formation of Heberden's and Bouchard's nodes. Imaging studies show a combination of bony proliferation (osteophytosis), periosteal reaction, and articular erosions, which assume "gull-wing" configuration. Differential diagnosis includes classic "degenerative" OA, rheumatoid arthritis, and psoriatic arthritis.
侵蚀性骨关节炎（EOA）是一种影响手部指间关节的进行性疾病。严重滑膜炎叠加在传统指间骨关节炎（OA）的典型变化之上，传统指间骨关节炎包括赫伯登结节和布夏尔结节的形成。影像学研究显示骨增生（骨赘形成）、骨膜反应和关节侵蚀的组合，呈“鸥翼”形态。鉴别诊断包括典型的“退行性”OA、类风湿关节炎和银屑病关节炎。
