F Terminology Relating to Spinal Implants. It is not the intention of this guide to address the analysis of spinal implant constructs or subconstructs or to define levels of performance of spinal implants as insufficient knowledge is available to predict the consequences of the use of particular spinal implant designs.

The force-displacement curves are recorded and evaluated with regard to the mechanical properties including stiffness and strength. Please login to your authorized staff account to use this feature. This test method outlines standardized evaluations of different interconnection mechanisms to facilitate comparison between different designs.

Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct. Print 1 2 3 4 5 page sstarting from page current page.

Fatigue testing in a simulated body fluid f17988 saline may have a fretting, corrosive, or lubricating effect on the interconnection and thereby affect the relative performance of tested devices.

From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants:. Enter your personal account email address to request a password g1798 You may delete a document from your F178 Profile at any time.

Comparisons must be made cautiously and with careful analysis, taking into account the effects that design differences can have on the loading configurations. Following the dynamic tests, the axial joint strength is tested under torsion to determine residual stability. One side of the longitudinal element is firmly clamped while asrm other side remains free. Hence, the test environment, whether a simulated body fluid, saline 9g NaCl per mL H 2 Owith a saline drip, or dry, is an important characteristic of the test and must be reported accurately.

Flexion extension and transversal moment: The mechanical tests are conducted in vitro using simplified, unidirectional loads and moments.

A substructure consists of an element for the connection to a vertebral body hook or screw and a longitudinally proceeding element rod or platewhich are connected to one another via a connecting mechanism.

It is the responsibility of the user of this standard to asstm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. If the partial construct fails before reaching the 2.

We have no amendments or corrections for this standard. However, the results can be used to compare different component designs in terms of relative mechanical parameters.

From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants: The connecting element serves as a lever arm, so that a moment about the x- or y-axis is generated. In this test, the connection stability between the connecting element and the longitudinal element is determined under torsion.
