The impact of uncemented acetabular interfaces at resisting progressive osteolysis through bone attachment and the formation of a biological seal was investigated. Total hip replacements (THR) surgery was performed in an ovine model. Femoral heads were roughened to generate wear debris and aseptic loosening of the acetabular component. The specimens were analyzed radiographically, histologically and using scanning electron microscopy (SEM). Light microscopy of thin sections in all groups revealed the common mechanism of loosening involving a resorption wedge at the interface with progressive bone loss.
