Does Femoral Neck to Cup Impingement Affect Metal Ion Levels in Hip Resurfacing?

摘要

BackgroundImpingement of the femoral neck with the acetabular component after metal-on-metal hip resurfacing arthroplasty (HRA) is a possible cause of edge loading and accelerated bearing wear. No attempt has been made to correlate radiographic impingement signs and blood metal ion levels.
