Significance and Use
5.1 This test method should be used to evaluate and compare acetabular prostheses to assess the relative degree of constraint for the prosthesis and the damage tolerance under controlled laboratory conditions.
5.2 Although the methodology described attempts to identify physiologically relevant motions and loading conditions, the interpretation of results is limited to an in vitro comparison between acetabular prosthesis designs regarding constraint and their ability to resist impingement fatigue, wear, deformation, and dislocation under the stated test conditions.
1.1 This test method covers a procedure to evaluate acetabular component fatigue, deformation, and wear and femoral head assembly dislocation under dynamic impingement conditions.
1.2 This test method can be used to evaluate single-piece acetabular prostheses, modular prostheses, and constrained prostheses manufactured from polymeric, metallic, or ceramic materials.
1.3 The values stated in SI units are regarded as the standard.
1.4 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.
