1. Scope
1.1 This test method describes a laboratory method for evaluating the potential for acetabular devices to corrode, generate debris, or fracture under repeated forces in a simulated environment. 1.2 The test described is applicable to any acetabular device used as part of a total hip replacement (THR). 1.3 Although the methodology described does not replicate all physiological force conditions, it is a means of in-vitro comparison of acetabular device designs under repeated forces in a simulated environment. 1.4 The values stated in SI units are regarded as the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
There does not exist a current standard test method for evaluating the fatigue resistance of acetabular systems for total hip replacement. There have been fractures of such devices clinically.
