The 2014 Frank Stinchfield Award: The ‘Landing Zone’ for Wear and Stability in Total Hip Arthroplasty Is Smaller Than We Thought: A Computational Analysis

摘要

BackgroundPositioning of total hip bearings involves tradeoffs, because cup orientations most favorable in terms of stability are not necessarily ideal in terms of reduction of contact stress and wear potential. Previous studies and models have not addressed these potentially competing considerations for optimal total hip arthroplasty (THA) function.
