Femoral head prosthesis BIOLOX® delta

The next generation of ceramics is now available for articulation with Connexion GXL®, our low wear, fracture tough polyethylene. This material also provides a new ‘option’ for using a ceramic femoral head in a revision scenario with the BIOLOX®OPTION.* Science Behind the Material Aluminum oxide matrix consisting of approximately 80% alumina, 17% zirconia and 3% strontium oxide. Zirconia was added to increase the material strength and prevent the initiation and propagation of cracks. An additional toughening mechanism is created with the addition of strontium oxide, which forms a platelet type crystal to dissipate energy by deflecting cracks.
