Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers materials and design recommenda-tions and general test methods for the
3、chemical, mechanical,and preclinical assessment of implantable devices with hard-on-hard articulations intended to replace a hip joint. Theprovided guidance is intended to encompass both Total HipReplacement (THR) devices with stems that extend or fixwithin the intramedullary canal as well as Hip Re
4、surfacingArthroplasty (HRA) wherein only the hip articulating surfacesare replaced. There has been long term clinical experience withmetal-on-metal articulating components manufactured fromcobalt-28 % chromium-6 % molybdenum (Co28Cr6Mo) alloy(Specifications F75, F799,orF1537) or high purity alumina(
5、ISO 6474-1) and ceramic-on-ceramic articulating componentsmanufactured from high purity alumina (ISO 6474-1) oralumina matrix composite ceramics (ISO 6474-2). There hasalso been some limited clinical experience with metal(Co28Cr6Mo) on alumina matrix composite ceramic articulat-ing components. This
6、guide has been created based on thecurrent understanding derived from those clinical histories.Device articulating components manufactured from other me-tallic alloys, ceramics or with coated or elementally modifiedarticulating surfaces could also be evaluated with this guide.However, such materials
7、 that do not have a history of clinicaluse may present different risks.1.2 This guide applies to the acetabular and femoral articu-lating components of hard-on-hard hip replacement devices.Acetabular components can be monoblock, or a modularcomponent with a separate acetabular shell and acetabularli
8、ner.As stated above, articulating components have been madefrom Co28Cr6Mo for a metal-on-metal bearing; high purityalumina or alumina matrix composite ceramics for a ceramic-on-ceramic bearing; and Co28Cr6Mo and alumina matrixcomposite (ISO 6474-2) for a metal-on-ceramic bearing.Modular acetabular s
9、hells have to date been made fromTi-6Al-4V or Co28Cr6Mo. The shell is considered part of theacetabular component. Acetabular components may have ex-ternal coating and/or porous structure intended foruncemented, press-fit or biological fixation; or, for use withbone cement.1.3 This standard is a summ
10、ary of available specifications,test methods, practices, and guides from published standards orthe scientific literature. Their clinical relevance is unproven.Most of the methods do not have an established precision andbias; therefore, their repeatability and reproducibility has notbeen established.
11、 As the clinical relevance of these methodshave not been established, consequently, most do not haveperformance requirements. This document does not requirethat all the listed methodologies are always necessary toevaluate these implant systems provided justification for notusing each unused method i

This document does notintend to prevent the use of new methodologies as they aredeveloped.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, healt
