Are you sure you want to empty the cart? It is not the intention of this test method to ast, 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. In this test, the connection stability between the connecting element and the longitudinal element is determined under torsion.
The results obtained here cannot be used directly to predict in vivo performance. Flexion extension and transversal moment: Your Alert Profile lists the documents that will be monitored.
From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants:.
No items in cart. Subscription pricing is determined by: Dynamic test methods Following the static tests, the tests with new test specimens are performed dynamically over 2.
Within the scope of the test, loads and moments are applied in three directions corresponding to a vertebral body: Historical Version s – view previous versions of 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.
This standard is not included in any packages. We offer various test methods for the mechanical characterization of partial constructions of spinal implants according to ASTM F This standard is also available to be included in Standards Subscriptions. Already Subscribed to this document.

Spinal implant constructs are designed to provide some stability to the spine while arthrodesis takes place.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

ASTM F1798 Partial constructions for spinal implants
The longitudinal component is firmly clamped in the test device and a load max. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct.
Standards Subsctiption may aatm the perfect solution. In this test, the connection stability between the connecting element and the longitudinal element is determined.
The connecting element serves as a lever arm, so that a moment about the x- asfm y-axis is generated.

Accreditation certificate arrived F Terminology Relating to Spinal Implants. 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.

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. Today, some 12, ASTM standards are atsm around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Following the dynamic tests, the axial joint strength is tested under torsion to determine residual stability.
