ASTM International Standard Specification for Elastomeric Flexible Hinge Finger Total Joint Implants ASTM F1781-21

This specification covers the biocompatibility and other performance requirements, and associated test methods for elastomeric flexible hinge finger total joint implants, used with and without metal grommets in the reconstruction of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. This specification excludes those implants that do not have an across-the-joint elastomeric linkage, and is limited to implants made from one material in a single one-step molding procedure.
