The article presents a study on the influence of shell deformation in the locking-mechanism integrity of contemporary modular acetabular designs of ceramic liners. A test is performed on two commercially acetabular shell systems namely the Equator Plus made from cobalt-chromium-molybdenum banded alumina liner surrounded with titanium alloy and the LINEAGE made from the same material in Equator Plus. Moreover, the cobalt-chromium-molybdenum will likely diminish any ceramic liner deformation.
