Standard Test Method for Functional and Wear Evaluation of Motion-Preserving Lumbar Total Facet Prostheses

Importancia y uso:

4.1 This test method can be used to describe the function, kinematics, and wear behavior of total facet prostheses subjected to cyclic loading/motion for relatively large numbers of cycles. (For example, various designs of total facet prostheses, as well as the effects of materials, manufacturing techniques, and other design variables on one particular design can be studied using this test method.)

4.2 This test method is intended to be applicable to total facet prostheses that support and transmit motion by means of an articulating joint or by use of compliant materials. Ceramics, metals, and/or polymers may be used in total facet prosthesis design, and it is the goal of this test method to enable a kinematic wear comparison of these devices, regardless of material and type of device.
