Standard Practice for Fretting Corrosion Testing of Modular Implant Interfaces: Hip Femoral Head-bore and Cone Taper Interface

This document outlines a standardized method for evaluating the effects of fretting corrosion on modular implant interfaces, specifically focusing on the head stem hole and conical stem interface in hip prostheses. It provides detailed procedures for conducting tests that simulate the mechanical and environmental conditions experienced by these components within the human body. The practice includes specifications for test apparatus, materials, and conditions necessary to replicate the micro-motion and corrosive environments that may occur during implantation and long-term use. The method is intended to support the assessment of implant performance and reliability, ensuring consistent and repeatable results across different testing facilities. The procedure encompasses the preparation of test specimens, the application of cyclic loading, and the measurement of corrosion-related damage. The standard is applicable to the development, testing, and evaluation of modular orthopedic implants used in hip replacement applications.
