“…11 On the other hand, alumina and yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) have been used as bearing components in TJR. Alumina components have been used for about 30 years, 12 although there have been concerns about the risk of component fractures. 13 Y-TZP has been clinically applied in articulation with PE in TJR in the expectation that it would contribute to the reduction of PE wear, 14 but it is still unknown whether the zirconia-on-PE system would really produce less wear in clinical use than metal-or alumina-on-PE systems.…”

The objectives of this study were to investigate the biocompatibility, phase stability, and wear properties of a newly developed Ce-TZP/Al(2)O(3) nanocomposite, as compared to conventional ceramics, and to determine whether the new composite could be used as a bearing material in total joint prostheses. In tests of mechanical properties, this composite showed significantly higher toughness than conventional Y-TZP. For biocompatibility tests, cylindrical specimens of both the Ce-TZP/Al(2)O(3) nanocomposite and monolithic alumina were implanted into the paraspinal muscles of male Wistar rats. The tissue reactions were almost the same, and at 24 weeks after implantation, thin fibrous capsules with almost no inflammation were observed around both of them. There were no significant differences in membrane thickness between the two ceramics. After hydrothermal treatment in 121 degrees C vapor for 18 h, the new composite showed complete resistance to aging degradation, whereas Y-TZP showed a phase transformation of 25.3 vol% (initial 0.4%) to the monoclinic form. According to the results of pin-on-disk tests, the wear rates of Ce-TZP/Al(2)O(3) nanocomposite and alumina were 0.55 +/- 0.04 x 10(-7) and 2.12 +/- 0.37 x 10(-7)mm(3)/Nm, respectively. The results of this study suggest that the Ce-TZP/Al(2)O(3) nanocomposite is a promising alternative ceramic component for total joint replacement.

“…Et ce « retour » vers le sans ciment est indissociable du nom de chirurgiens français : J. et R. Judet • P. Boutin, en 1972, a présenté une étude expérimen-tale de la fixation sans ciment d'une cupule en alumine [9] ; il est rapidement arrivé au concept de l'insert en alumine dans une cupule « métal-back » dont il a rapporté les premiers résultats en 1977 [10]. • G. Bousquet, en 1976, a proposé sa cupule à double mobilité dont la cupule métallique n'était pas cimentée [11].…”

“…Boutin 1969 war der erste, der vorschlug, Keramik in ein Hüftgelenk einzusetzen [2]. In den 1970er Jahren wurden dann keramische Köpfe und Pfannen auch im deutschsprachigen Raum eingesetzt.…”

“…In der Hüftgelenksendoprothetik ist dies weit ausgedehnter, als zum Beispiel in der Kniegelenksendoprothetik, da der Polyethylenabbrieb und damit verbundene Osteolysen weit mehr die Lebensdauer des Implantates beeinflussen [1]. Bereits vor drei Jahrzehnten führ-ten Probleme mit der Haltbarkeit von Polyethylengleitlagern zur Entwicklung von sogenannten Hartpaarungen, im speziellen seien hier die ersten Metall-Metall sowie Keramik-Keramik-Lager erwähnt [2,3]. Fehler im Design und in der Verankerung dieser frühen Prothesentypen ließen aber in weiterer Folge, ganz unabhängig von den artikulierenden Materialien, das Interesse daran schwinden.…”
