Today, some 12, ASTM standards are used around the world to improve product quality, enhance astk, facilitate market access and trade, and build ast, confidence. Enter your account email address to request a password reset: It is not the intention of 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.

The connecting element serves as a lever arm, so that a moment about the x- or y-axis is generated. 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.

ASTM F Partial constructions for spinal implants – Innoproof

Flexion extension and transversal moment: A moment-angle curve can be used to satm a significant drop in the torque, which marks the exceeding of the connection strength. Subscription pricing is determined by: 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.

Anterior-posterior and lateral loading: Print 1 2 3 4 5 page sstarting from page current page. The results obtained here cannot be used directly to predict in vivo performance.

ASTM F1798 – 13

Following the dynamic tests, the axial joint strength is tested under torsion to determine residual stability. Your Alert Profile lists the documents that will be monitored. 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.

Implant Testing

The force-displacement curves are astn and evaluated with regard to the mechanical properties including stiffness and strength. From the following range, we will select the appropriate test procedures for the partial aastm of your individual spinal implants:. Land Use and Development. In this test, the connection stability between the connecting element and the longitudinal element is determined under torsion. This standard is not included in any packages.

One side of the longitudinal element is firmly clamped while the other side remains free.

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 f1978 via a connecting mechanism. Please login to your authorized staff account to use this feature. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct. Please first verify your email before subscribing to alerts.
