ASTM F2790: Standard Practice for Functional and Wear Evaluation of Motion-Preserving Lumbar Total Facet Prostheses

ASTM F2694 provides guidance for the functional, kinematic and wear testing of motion-preserving total facet prostheses for the lumbar spine. These implants are intended to allow motion and lend support to the functional spinal unit(s) through replacement of the natural facets. This test method is not intended to address the bone implant interface or the static characteristics of the prosthesis components. Fatigue characteristics are included, but only as a by-product of cyclic wear testing under facet load and thus are not addressed in the typical process of generating an S-N characterization.

ASTM F2790 describes static and dynamic tests by specifying load types and specific methods of applying these loads.
