Standard Guide for High Demand Hip Simulator Wear Testing of Hard-on-Hard Articulations

Importancia y uso:

5.1 The current hip simulator wear test standards (ISO 14242-1 or ISO 14242-3) stipulate only one load waveform and one set of articulation motions. There is a need for more versatile and rigorous wear test regimes, but the knowledge of what represents realistic high demand wear test features is limited. More research is clearly needed before a standard that defines what a representative high demand wear test should include can be written. The objective of this guide is to advise researchers on the possible high demand wear test features that should be included in evaluation of hard-on-hard articulations.

5.2 This guide makes suggestions of what high demand test features may need to be added to an overall high demand wear test regime. The features described here are not meant to be all inclusive. Based on current knowledge they appear to be relevant to adverse conditions that can occur in clinical use.

5.3 All the test features, both conventional and high demand, could have interactive effects on the wear of the components.
