Presented at the 2nd Annual Total Hip Resurfacing Arthroplasty Course in LA Oct. 2008 By: John Fisher Co-Authors: Ian Leslie, Sophie Williams, Eileen Ingham, Graham Isaac Institute of Medical and Biological Engineering University of Leeds Background: There are considerable variations in metal ion levels and metallic wear rates in patients with metal on metal resurfacing. In this in vitro study the effect of design variables of head diameter and bearing clearance and patient variables |
