Scientific titleImproving the bearing surface in total hip replacement (THR): the use of oxidised zirconium and highly cross-linked polyethylene - a randomised controlled trial
Study objectivesDoes the use of oxidised zirconium femoral heads in total hip replacement reduce the rate of volumetric and linear wear as compared to conventional material heads, whilst providing comparable outcome measures?
Ethics approval(s)Joint UCL/UCLH Committees on the Ethics of Human Research (Committee A), 14/01/2005, ref: 04/Q0505/71
Health condition(s) or problem(s) studiedArthritis of the hip
InterventionPrimary total hip replacement, using either cobalt chrome or oxinium femoral heads and either standard or highly cross-linked polyethylene liners.
Intervention typeProcedure/Surgery
Primary outcome measureRadiographic wear; measuring linear & volumetric wear based on standardised AP & lateral radiographs of the pelvis then analysed with an automated edge detection technique
Secondary outcome measuresNot provided at time of registration
Overall study start date14/01/2009
Completion date01/09/2009
