Fatigue testing in a simulated body fluid or saline may have a fretting, corrosive, or lubricating effect on the interconnection and thereby affect the relative performance of tested devices. This standard is not included in any packages. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct. A force-displacement curve reveals a significant drop in force, which marks the exceeding of the ast strength.

It is not the intention astj this test method 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.
A moment-angle curve can be used to determine a significant drop in the torque, which marks the exceeding of the connection strength. The force-displacement curves are recorded and evaluated with regard to the mechanical properties including stiffness and strength.

Land Use and Development. We offer various test methods for the mechanical characterization of partial constructions of spinal implants according to ASTM F The connecting element serves as a lever arm, so that a moment about the x- or y-axis is generated.

Comparisons must be made cautiously and with careful analysis, taking into account the effects that design differences can have on the loading configurations.

Flexion extension and transversal moment: Within the scope of the test, loads and moments are applied in three directions corresponding to a vertebral body: Already Subscribed to this document.

One side of the longitudinal element is firmly clamped while the other side remains free. You can download and open this file to your own computer ff1798 DRM prevents opening this file on another computer, including a networked server.
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 adtm connecting mechanism. There were no books found for the applied search filters. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. We have no amendments or corrections for this standard.

In this test, the connection stability between the connecting element and axtm longitudinal element is determined under torsion.
Spinal implant constructs are designed to provide some stability to the spine while arthrodesis takes place.
Accreditation certificate arrived 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 longitudinal component is firmly clamped in the test device and a load max. Need more than one copy? Are you sure you want to empty the cart? 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.

Anterior-posterior and lateral loading: Dynamic test methods Following the static tests, the tests with new test specimens are performed dynamically over 2. From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants:. If the partial construct fails before reaching the 2.
