Although good mid-term results have been reported with some metal on metal hip replacements, reported complications due to metal on metal (MOM) related reactions are a cause for concern. We have assessed the early clinical outcome and results of routine metal artefact reduction MRI findings in a consecutive series of patients with a modern large head metal on metal hip replacement. 62 ASR XL Corail total hip replacements (THR) and 17 ASR resurfacings were performed at our hospital between 2005 and 2008. All patients were reviewed and assessed with an Oxford hip score (OHS), a plain radiograph and a MRI imaging was obtained on 76 (96%) hips. Implant position was assessed using Wrightington cup orientation software.Introduction
