ASTM F Partial constructions for spinal implants – Innoproof
Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct. Subscription pricing is determined by: Today, adtm 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
However, the results can be used to compare different component designs in terms of relative mechanical parameters. 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. Please login to your authorized staff account to use this feature. The force-displacement curves are recorded and evaluated with regard to the mechanical properties including stiffness and strength.

Remember me for one month. Historical Ast, s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard.
Proceed astk Checkout Continue Shopping. As the voice of the U. In this test, the connection stability between the connecting element and the longitudinal element is determined under torsion.
We offer various test methods for the mechanical characterization of partial constructions of spinal implants according to ASTM F Please first log in with a verified email before subscribing to alerts. A moment-angle curve can be used to determine a significant drop in the torque, which marks the exceeding of the connection strength. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Dynamic test methods Following the static tests, the tests with new test specimens are performed dynamically over 2. Hence, the test environment, whether a simulated body fluid, saline 9g NaCl per mL H 2 O aetm, with a saline drip, or dry, is an important characteristic of the test and must be reported accurately.

It is not the intention of this test method to address the analysis of spinal aetm 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.

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