Please confirm that you agree with our privacy and cookies policy to submit this form. This test should be initially performed dry ambient room conditions for consistency. How can we help you? Spinal implant assemblies are designed to provide some stability to the spine while arthrodesis takes place. The ElectroPulsTM E is a state-of-the-art, all-electric test instrument designed f17177 dynamic and static testing on a wide range of materials and components.
They allow comparison of spinal implant constructs with different intended spinal locations and methods of application to the spine.
The test materials for most combinations of spinal implant components can be f17117, depending on the intended spinal location and intended method of application to the spine.
Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, asstm air, hydraulics, or water.
ASTM F Spinal Implant Testing – ADMET
f17717 Contact our Engineers Today! 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.
Work Item s – proposed revisions of this standard. Sales Support Calibration Calculators.
ASTM F Spinal Implant Construct Biaxial Testing – ADMET
Compressive Bending Fatigue Test — Apply a constant load amplitude sinusoidal control profile at no faster atm 5Hz. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Simple static testing is able to evaluate the load required to result in spinal fracture. The ElectroPulsTM E Linear-Torsion is a state-of-the-art, all-electric test instrument designed for dynamic and static testing on a wide range of materials and components.
Didn’t get the message? 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.
Email addresses can only contain letters, numbers and the following special characters: A constant load ratio, R, for all tests should be established and should be greater than or equal to The results can be used to compare different component designs in terms of the relative mechanical parameters.

Historical Version s – view previous versions of standard. The three static tests are compression bending, tension bending and torsion.
Featured Configurations for Spinal Implant Testing. Spinal injuries often occur due to rotation, dislocation, bending, and axial loading. Loading is typically applied with a constant-amplitude, load-controlled sinusoidal waveform, running in excess of five million cycles.
The mechanical tests are conducted using simplified loading schemes and do not attempt to mimic the complex loads of the spine. The 55MT MicroTorsion system can be used when multiple revolutions are required.
The fatigue test is a compression bending test. 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.
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.
ASTM F1717 Spinal Implant Testing
These test methods are not intended to define levels of performance, since sufficient knowledge is not available to predict the consequences of the use of a particular device.
Automotive Interior Mechanical Testing Guide. Cyclic testing is also performed in order to evaluate the amount of cycles it takes asm fatigue failure to occur.
Email addresses must contain the symbol. Preclinical evaluation of spinal implants is a necessary step to ensure their reliability and safety before implantation. The American Society for Testing and Materials reapproved F standard for the assessment of mechanical properties of posterior spinal fixators, which simulates a vertebrectomy model and recommends mimicking vertebral bodies using polyethylene blocks.
ASTM F1717 Testing of Spinal Constructs, Static, Fatigue, Torsion
Spinal Fixtures ASTM F astj CP During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies.
How to Build a New Test.
Epub Oct The results obtained here cannot be used directly to predict ff1717 vivo performance. ASTM F is intended to provide a basis for the mechanical comparison among past, present and future spinal implant assemblies.
