Cemented ceramic acetabular component: a 7-year review.
A 7-year review of 30 cases of cemented ceramic acetabular components has shown that all components rapidly become surrounded by a lucent zone between the cement and bone that appears to be nonprogressive. Although these prostheses have functioned well, some separation inferiorly between the ceramic cup and the cement suggests that "creep" of the cup within the cement occurs and that the cup should be modified to provide greater "pull out" resistance from the cement. This study has failed to substantiate some of the theoretical advantages of ceramic cups.
