Abstract

We have implanted 371 CLS acetabular components in our centre since 1989. Despite design changes in the component we report 4 cases of failure by fracture through the metal backing of the cup. Our aim is to highlight this uncommon mechanism of failure and advise that in cases of unexplained hip pain in those with CLS acetabular components X rays in at least 2 planes are performed.

The abstracts were prepared by Mr Peter Kay, Editorial Secretary. Correspondence should be addressed to British Hip Society, The Hip Centre, Wrightington Hospital, Appley Bridge, Wigan, Lancashire WN6 9EP.
