In vitro comparison of the effects of rough and polished stem surface finish on pressure generation in cemented hip arthroplasty.

Abstract:

BACKGROUND AND PURPOSE: High pressures around implants can cause bone lysis and loosening. We investigated how pressures are generated around cemented femoral stems. METHOD: We compared the pressures generated by rough and polished tapered stems at their cement interfaces, in an in vitro model, before and after 1 million load cycles. RESULTS: At the start of the study, the loading of both polished and rough stems generated interface pressures that were not statistically significantly differe...
