Catastrophic failure of an uncemented acetabular component due to high wear and osteolysis: An analysis of 154 Omnifit prostheses with mean 6-year follow-up
Background The purposes of this study were (1) to evaluate the wear pattern of the hydroxyapatite-coated "Dual Radius" Omnifit cup, (2) to investigate whether wear is correlated to any demographic or prosthesis-related factors, and (3) to describe micromotion of both the cup and the stem. Patients and methods 154 hips were implanted between 1990 and 1996 and followed for an average of 6 years. Wea
