The importance of adequate stem anteversion for rotational stability in cemented total hip replacement: A radiostereometric study with ten-year follow-up.
Progressive retroversion of a cemented stem is predictive of early loosening and failure. We assessed the relationship between direct post-operative stem anteversion, measured with CT, and the resulting rotational stability, measured with repeated radiostereometric analysis over ten years. The study comprised 60 cemented total hip replacements using one of two types of matt collared stem with a ro
