Next to aseptic loosening, recurrent dislocation is the second leading cause of failure in total hip arthroplasty [1]. Impingement of the femoral component neck on the acetabular cup is a frequent mechanism. Dislocation rates range from 2–11% in primary THA surgeries, and up to 25% or more in revisions [2]. Despite this high incidence, little is known about contributory component design factors. A finite element (FE) model has therefore been developed to systematically study impingement and dislocation resistance.
