Repeating all or part of these test methods in simulated body fluid, saline 9 g NaCl per mL watera saline drip, water, or a lubricant should be considered. The results obtained here cannot be used directly to predict in vivo performance. We are confident that we have what you are looking for. Other mechanical variables, describing implant design were considered, and all parameters were investigated using a numerical parametric finite d1717 model.
Email addresses can only contain letters, numbers and the following special characters: Next Checking to see if you are a returning visitor…. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine asgm applicability of regulatory limitations prior to use.
ASTM F1717 Testing of Spinal Constructs, Static, Fatigue, Torsion
Concrete, Asphalt and Rock. This set-up should represent the clinical use, but available data in the literature are few. Onsite Training At Your Facility. Our universal testing systems are ideal for static tensile d1717 compressive tests.
Contact Us View Accessories Catalog. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies.
Simple static testing is able to evaluate the load required to result in spinal fracture.
Additionally fatigue tests are employed to quantify the static and dynamic mechanical characteristics of different designs of spinal implant assemblies. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies.

It is the ast of the user of this f717 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The mechanical tests are conducted in vitro using simplified load schemes and do not attempt to mimic the complex loads of the spine. 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 55MT MicroTorsion system can be used when multiple revolutions are required.
This test should be initially performed dry ambient room conditions for consistency. The ElectroPulsTM E is a state-of-the-art, all-electric test instrument designed for dynamic and static testing on a wide range of materials and components. Powered entirely from a single-phase mains supply, they feature the latest in testing technology and a host of other user-oriented features.
The mechanical tests are conducted in vitro using simplified load schemes. Software for Series Systems. The worst-case combination of parameters demonstrates that devices implanted below T5 could potentially undergo higher stresses than those described in the standard suggestions maximum increase of 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.
Preclinical evaluation f1177 spinal implants is a necessary step to ensure their reliability and safety before implantation. 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.
Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! 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.
