【摘要】 为探讨成纤维细胞（ Ｆｂ） 在无菌性松动中的作用。对髋关节翻修所获界膜（ 组１） 、相应髋关节滑膜（ 组２） 、内固定物周围异物反应组织（ 组３） 及正常髋关节滑膜（ 组４） 中 Ｆｂ 的分布及形态学进行了组织学与超微结构的对比观察。结果显示：成纤维细胞在各组中的分布及形态表现不同，组１ 与组２ 中呈现功能活跃相，而组３ 与组４ 中呈相对静止状态。提示 Ｆｂ 对假体松动及骨溶解有影响。更多还原

【Abstract】 Objective To analyze the nonbacterial loosening cause in artificial arthroplasty and the function of fibroblasts. Methods :The observation on the histology and ultrastructure of Fb in the interface membrane following revision of hip joint (group l),relevent hip joint synovium (group 2),reaction materials around intra-fixture (group 3) and normal hip joint synovium (group 4). Results Different shape and function of the Fb in the 4 groups were noted.In groups 1 and 2 the Fb showed active, and in groups 3 and 4,they were relatively static.Conclusion Fibroblasts involve in prothetic loosening.更多还原
