A SEVEN YEAR MULTI-CENTRE FOLLOW-UP OF THE CORMET RESURFACING SYSTEM

Coventry and Warwickshire Hospital, Orthopaedic Department, Stoney Stanton Road, Coventry DV1 4FH

We present an independent multi-centre follow-up of metal-metal resurfacing from district regional hospitals (DGHs) in a series of ‘young’ patients with implants from a single manufacturer.

Between November 1995 and November 2002, two hundred and thirteen primary total hip resurfacings were performed in six centres. Two hundred and ten patients were followed up with none lost to follow-up. The average age of the patient group was 52.9 years range (21.9–71.3 years). Of these 210 patients 119 were male and 91 were female. There were three bilaterals and five revisions recorded with a revision rate of 2.3% at seven years. The maximum duration of follow-up was 84 months, the minimum was 3 months and the mean follow-up was 43.5 months.

The average Harris Hip score at the latest follow-up review was 78.15 (range 23–100). The Kaplan-Meier Survivorship of Cormet was 95% at 7 years and a survivorship of 97.38% at three years. These results indicate that metal-metal resurfacing meets the NICE guidelines for suvivorship at the three year benchmark in DGHs with local patients and is on course to meet the 10 year benchmark despite the extremely demanding patient group.
