Abstract
The material BIOLOX®delta has been exposed to extreme conditions (accelerated ageing and cyclic loading in Ringer’s solution). It has been shown that even a combination of worst case conditions does not reveal any premature failure. Furthermore, it was shown that the residual strength remains on the initial level. A certain amount of phase transformation was observed during the tests. The highest amount of monoclinic phase relative to the total volume of the specimen was 47 %. The residual strength was not affected by the phase transformation. In other studies it was shown that BIOLOX®delta performs extremely well in severe wear tests (Clarke et al., Proceedings 10th BIOLOX symposium, 11–20, 2005). These results are also attributed to the reinforcing mechanism in the material. These exciting results promote the confidence that BIOLOX®delta offers the highest probability of long term durability in well designed artificial joint systems.
