ASTM WK28778

    New Test Method for Determination of Friction Torque and Friction Factor for Hip Implants Using an Anatomical Motion Hip Simulator

    (What is a Work Item?)

    Developed by Subcommittee: F04.22 | Committee F04 | Contact Staff Manager


    1. Scope

    1.1 This test method provides a method of evaluating the friction torque and friction factor of artificial hip joint bearings used in total hip replacement systems. This test method was based on a published study and is compatible with and capable of being carried out during actual wear testing of total hip replacement implants on wear simulators equipped with multi-degree-of-freedom force and moment sensors. 1.2 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.

    Friction can have a significant effect on wear. The ability to measure the friction in an articulating hip joint will be useful in understanding the long-term wear character of a new hip joint system.

    The title and scope are in draft form and are under development within this ASTM Committee.
