Morphometric and microanalytical analyses of alumina wear particles in hip prostheses.
We analysed tissues harvested during 24 retrievals of hip joint prostheses, with one or both articular components made of alumina. We describe the morphology of wear particles, measure their size and analyse their chemical composition. We relate histopathological aspects to the parameters that characterize ceramic wear particles, and notice that tissue reaction relates to the physical aspect and amount of wear debris and does not necessarily depend on their chemical composition.
