title: Insufficiency os pubis fractures in rheumatoid arthritis.
abstract: There is a paucity of information regarding insufficiency fractures of the os pubis in rheumatoid arthritis. While only 7 such fractures have been recorded thus far in the English literature, we have encountered 5 os pubis fractures in the past 4-year period. We report these cases to heighten awareness of their existence, describe their sometimes misleading clinical presentations, and to discuss possible etiologic factors.
