title: [Histological analysis of the bone/prosthesis interface in man after implantation of a hip prosthesis coated with plasma-sprayed hydroxyapatite].
abstract: Thin coatings of calcium phosphate hydroxyapatite on metal alloys provide to these materials biological properties of calcium phosphates. We have analysed, using histological techniques or newly developed scanning electronic microscopy techniques, hip prostheses implanted into humans for periods from a few days up to twenty six months. The results of these analyses confirm the good osteointegration of these prostheses observed during clinical studies. Moreover, an active remodeling of the bone in contact with the ceramic-coating was observed. The coating was also concerned by the remodeling process and evolved once implanted.
