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

Abstract

Positioning THA bearings involves tradeoffs regarding stability and long-term bearing wear. Cup positions most favorable to minimization of wear such as low inclination and elevated anteversion were detrimental in terms of construct stability. Orientations were identified that best balanced the competing considerations of wear and stability.
