Trunnionosis: Does Head Size Affect Fretting and Corrosion in Total Hip Arthroplasty?

摘要

Background: Wear and tribocorrosion at the modular headeneck taper interface may be a cause of failure in metal-on-polyethylene total hip arthroplasty (THA). The present investigation endeavored to elucidate the effect of femoral head diameter on fretting and corrosion in retrieved headeneck tapers.
