From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants: As the voice of the U. The results obtained here cannot be used directly to predict in vivo performance. Are you sure you want to empty the cart? The force-displacement curves are recorded and evaluated with regard to the mechanical properties including stiffness and strength. If you like to setup a quick demo, let us know at support madcad.
Dynamic test methods Following the static tests, the tests with new test specimens are performed dynamically over 2. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct.
Standards Subsctiption may be the perfect solution. In this test, the connection stability between the connecting element and the longitudinal element is determined under torsion. Remember me for one month.
The connecting element serves as a lever arm, so that a moment about the x- or y-axis is generated. Flexion extension and transversal moment: From the following range, we will select the asttm test procedures for the partial constructs of your individual spinal implants:.

Fatigue testing in a simulated body fluid or saline may have a fretting, corrosive, or lubricating effect on the interconnection and thereby affect the aatm performance of tested devices. If the document is revised or amended, you will be notified by email.

Historical Version s – view previous versions of standard. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct. It is the responsibility of the user of this standard to establish appropriate safety and health practices ast, determine the applicability of regulatory limitations prior to use.
Asym Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Following the dynamic tests, the axial joint strength is tested under torsion to determine residual stability. However, the results can be used to compare different component designs in terms of relative mechanical parameters.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
If the partial construct fails before reaching the 2. There were no books found for the applied search filters. Please login to your authorized staff account to use this feature.

A moment-angle curve can be used to determine a significant drop in the torque, which marks the exceeding of the connection strength.

Subscription pricing is determined by: 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. One side of the longitudinal element is firmly clamped while the other side remains free.
