Abstract
We analysed tissues harvested during 24 retrievals of hip joint prosth eses, with one or both articular components made of alumina. We descri be the morphology of wear particles, measure their size and analyse th eir chemical composition. We relate histopathological aspects to the p arameters that characterize ceramic wear particles, and notice that ti ssue reaction relates to the physical aspect and amount of wear debris and does not necessarily depend on their chemical composition.
