Migration and wear of the Duraloc "1200 series" cup associated with Enduron UHWMPE using the EBRA method and the Imagika software.
We report a retrospective study on 122 THA using Duraloc "1200 series" cups. All patients received a 28-mm head (107 Al2O3, 15 CoCr). The mean age of the patients at surgery was 56.3 years and the mean follow-up was 137 months.Mean migration at two years using the EBRA method was 0.18 mm cranially and 0.16 mm medially. Mean polyethylene wear was 0.03 mm/year using the Imagika software and 0.06 mm/year using EBRA. Only one patient presented with abnormal polyethylene wear of 1.7 mm at 90 months with Imagika and 2.4 mm with EBRA. The Duraloc cup seems to be a reliable implant in respect of bone fixation and resistance to wear.
