Scientific title | Improving the bearing surface in total hip replacement (THR): the use of oxidised zirconium and highly cross-linked polyethylene - a randomised controlled trial |
Study objectives | Does 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) studied | Arthritis of the hip |
Intervention | Primary total hip replacement, using either cobalt chrome or oxinium femoral heads and either standard or highly cross-linked polyethylene liners. |
Intervention type | Procedure/Surgery |
Primary outcome measure | Radiographic wear; measuring linear & volumetric wear based on standardised AP & lateral radiographs of the pelvis then analysed with an automated edge detection technique |
Secondary outcome measures | Not provided at time of registration |
Overall study start date | 14/01/2009 |
