ASTM F1717 Spinal Implant Static and Fatigue Test Equipment

Spinal implant assemblies are designed to provide some stability to the spine while arthrodesis takes place. No other units of measurement are included in this standard.

Repeating all or part asfm these test methods in simulated body fluid, saline 9 g NaCl per mL watera saline drip, water, or a lubricant should be considered. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! ASTM F tests include static compression bending, tension bending, and torsion tests. The mechanical tests are conducted in vitro using simplified load schemes and do not attempt to mimic the complex loads of the spine.

By means of our orthopaedic testing expertise and modular product design, we will help find the testing solution that is right for you. ASTM F covers the materials and methods for the static and fatigue testing of spinal implant assemblies in a vertebrectomy model.

ASTM F Spinal Implant Static and Fatigue Test Equipment

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

Email addresses must contain the symbol. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies. Spinal Fixtures ASTM F – CP During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure.

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.

ASTM F – 18 Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model

Link to Active This link will always route to the current Active version of the standard. Software for Series Systems. 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.

Static and fatigue forces up to 50 kN 11, lbf Frequency ratings up to 75 Hz Oil-free, all electric actuator for clean test conditions Lower purchase, operating, and mantenance costs than hydraulic equivalents. The mechanical tests are conducted f11717 vitro using simplified load schemes. The American Society for Testing and Materials reapproved F standard for the assessment of mechanical f17177 of posterior spinal fixators, which simulates a vertebrectomy model and recommends mimicking vertebral bodies using polyethylene blocks.

We propose to revise F in order to describe the anatomical worst case condition we found at L1 level: Powered entirely from a single-phase mains supply, they feature the latest in testing technology and a host of other user-oriented features. Email addresses can only contain letters, numbers and the following special characters: Contact Us View Asym Catalog. For application of torsional strain, we recommend any of our torsion tabletop testing systems. Onsite Training At Your Facility.

Our universal testing systems are ideal for static tensile and compressive tests. They allow comparison of spinal implant constructs with different intended spinal locations and methods of application to the spine.

Subscribe to Our Newsletters. Service life testing of spinal constructs is critical as fatigue failure is more common than catastrophic failure. During normal patient activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure.

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. This test should be initially performed dry ambient room conditions for consistency. 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.

The stress on the pedicular screw is significantly influenced by g1717 lever arm of the applied load, the unsupported screw length, the position of the centre of rotation of the functional spine unit and the pedicular inclination with respect to the sagittal plane. 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. Preclinical evaluation of spinal implants is a necessary step to ensure their asmt and safety before implantation.

Concrete, Asphalt and Rock. Glossary of Materials Testing Terms. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F Additionally fatigue tests are employed to quantify the static and dynamic mechanical characteristics of different designs of spinal implant assemblies.
