“…8 Advances in the manufacture of ceramics for hip prostheses include the addition of zirconium and strontium to alumina and changes in the design of the femoral taper to allow a thicker ceramic head. [9][10][11][12][13] However, problems with the use of ceramics have emerged, such as squeaking and, more significantly, fracture of the prosthesis, 14,15 with the results of revision being poor. 15 Therefore, despite the incidence of ceramic fracture falling to between 0% and 0.004%, 16 the very large numbers of ceramic bearings and catastrophic consequences of suboptimal management justify a review of the options for the surgeon should a ceramic fracture occur.…”

Fracture of a ceramic component in total hip replacement is a rare but potentially catastrophic complication. The incidence is likely to increase as the use of ceramics becomes more widespread. We describe such a case, which illustrates how inadequate initial management will lead to further morbidity and require additional surgery. We present the case as a warning that fracture of a ceramic component should be revised to another ceramic-on-ceramic articulation in order to minimise the risk of further catastrophic wear.

“…One is to reduce the friction and wear between the acetabular cup and the femoral head. General approach is to reduce mechanical wear by selecting different bearing surfaces, such as ceramics on ceramics, 6 metal on metal, 7 or ceramics on metal. 8 Another approach is to improve the wear resistance of UHMWPE acetabular cup, which has shown to be improved significantly by cross-linking, 9,10 filler modification [11][12][13] and ion implantation.…”

The objective of this study was to explore the possibility of UHMWPE implant used as the drug carrier to treat particle-induced osteolysis. 17beta-estradiol (E2), which had the potential application on osteolysis treatment and the high melting point, was added into UHMWPE powder to produce UHMWPE-E2 composites through hot press processing. The hydrophobicity, crystallinity, mechanical properties, and wear performance of the UHMWPE-E2 were characterized compared with the control UHMWPE. The thermal analysis and Fourier Transform Infrared Spectroscopy results demonstrated that the hot press processing would not alter the functional groups of E2 in this study. There were no significant differences in the hydrophobicity and crystallinity between the UHMWPE-E2 and UHMWPE. The UHMWPE-E2 showed satisfying mechanical properties, including ultimate tensile strength (47.2 +/- 3.6 MPa), yield strength (25.0 +/- 0.6 MPa) and elongation at break (320 +/- 25.5 %), which were similar with the control UHMWPE. The friction coefficients and worn scars were similar between the UHMWPE-E2 and the control UHMWPE. The wear mechanism of the UHMWPE-E2 and UHMWPE both were abrasive wear under dry friction. The UHMWPE-E2 possesses the approving mechanical properties and wear performance compared with the control UHMWPE, which might be used as the potential implanted drug carrier to prevent the particle-induced osteolysis in joint replacements.

“…Ist die Tribologie ausschlaggebend (z. B. bei Hüftkugel undpfanne) findet man bei artgleichen Paarungen nur noch CoCrMo-Legierungen; ansonsten werden Keramik-Keramik, Keramik-Polymer oder Metall-Polymer Paarungen mit Erfolg eingesetzt [7][8][9][10][11]. Obwohl die artgleiche Kombination von kubisch flächenzentrierten Werkstoffen unter Gleitverschleiß klassischen tribologischen Theorien widerspricht, zeigen sie in der klinischen Anwendung gute Ergebnisse.…”

Austenitic stainless steels provide a fair combination of strength, toughness and corrosion resistance. Undergoing tribological stresses -in particular under self-mating contact situations -their performance is not sufficient. Thus the more wear resistant austenitic Co-base alloys with different carbon contents are applied under these circumstances, which may prevail in medical applications. Austenitic high-Nitrogen Steels might be an alternative under these circumstances. Strength, corrosion resistance and tribologcial properties are similar to those of CoCrMo-alloys, while their toughness is higher. This contribution presents the metallurgical mechanisms, which bring about this combination of properties.
