For application of torsional strain, we recommend any of our asm tabletop testing systems. Description Literature Contact Us During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure. The mechanical tests are conducted in vitro using simplified load schemes and do not attempt to mimic the complex loads of the spine.

We are confident that we have what you are looking for. Methods for three static load f11717 and one fatigue test are defined for the comparative evaluation of spinal implant assemblies. No other units of measurement are included in this standard. During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure.

ASTM F1717 Spinal Implant Static and Fatigue Test Equipment

The mechanical tests are conducted in vitro using simplified load schemes. Stress values were calculated by considering either the combination of the average values for each parameter or their worst-case combination depending on the spinal level.

For asmt majority of spinal construct testing, ultra high molecular weight polyethylene UHMWPE blocks are used rather than vertebrae to eliminate the variances that bone properties and geometry may introduce. The effect of environment may be significant. Historical Version s – view previous versions of standard. Asmt addresses can only contain letters, numbers and the following special characters: Spinal implant assemblies are designed to provide some stability to the spine while arthrodesis takes place.

Powered entirely from a single-phase mains supply, they feature the latest in testing technology and a host of other user-oriented features. Additionally fatigue tests are employed to quantify the static and dynamic mechanical characteristics of different designs of spinal implant assemblies.

By means of asmt orthopaedic testing expertise and modular product design, we will help find the testing solution that is right for you. Contact Us View Accessories Catalog. Loading is r1717 applied with a constant-amplitude, load-controlled sinusoidal waveform, running in excess of five million cycles.

These test methods outline standard materials and methods for the evaluation of different spinal implant assemblies so that comparison between different designs may be facilitated.

Subscribe to Instron News! Repeating all or part of these test methods in simulated body fluid, saline 9 g NaCl per mL watera saline drip, water, or a f717 should be considered. The standard set-up represents quite well the anatomy of an instrumented average thoracolumbar segment. No other units of measurement are included in this standard.

Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies. Glossary of Materials Testing Terms.

These test methods are not intended to define levels of performance, since sufficient knowledge is not available to atsm the consequences of the use of a particular aatm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Service life testing of spinal constructs is critical as fatigue failure is more common than catastrophic failure. Subscribe to Our Newsletters. The test materials for most combinations of spinal implant components can be specific, depending on the intended spinal location and intended method of application to the spine.

The 55MT MicroTorsion system can be used when multiple revolutions are required. Preclinical evaluation of spinal implants is a necessary step to ensure their reliability and safety before implantation. Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water.
