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. The standard set-up represents quite well the anatomy of an instrumented average thoracolumbar segment.

Historical Version s – view previous versions of standard. 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 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.

Have a question about conducting the test for this standard? The 55MT MicroTorsion system can be used when multiple f717 are required. No other units of measurement are included in this standard.

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.

These test methods are not intended to define levels of performance, since sufficient knowledge is xstm available to predict the consequences of the use of a particular device. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies. Concrete, Asphalt and Rock. No other units of measurement are included in this standard. Our universal testing systems are ideal for static tensile and compressive tests.

Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies. ASTM F tests include static compression bending, tension bending, and torsion tests. 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, atsm mantenance costs than hydraulic equivalents. Spinal implant assemblies are designed to provide some stability to the spine while arthrodesis takes place.

They allow comparison of spinal implant constructs with different intended spinal locations and methods of application to the spine.

WaveMatrix 2 for Dynamic Testing. Additionally fatigue tests are employed to quantify the static and dynamic mechanical characteristics of different designs of spinal implant assemblies.

Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This set-up should represent the clinical use, but available data in the literature are few.

The mechanical tests are conducted in vitro using simplified load schemes and do not attempt to mimic the complex loads of the spine. 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. Other mechanical variables, describing implant design were considered, and all parameters were investigated using a numerical parametric finite element model.

Simple static testing is able to evaluate the load required to result in spinal fracture. Active view current version of standard. Spinal injuries often occur due to rotation, dislocation, bending, and axial loading. Cyclic testing is also performed in order to evaluate the amount of cycles it takes for fatigue failure to occur. By continuing to use our site, you accept our cookie policy. Service life testing of spinal constructs is critical as fatigue failure is more common than catastrophic failure.
