ASTM F2077 Intervertebral body fusion devices testing equipment

Static and dynamic testing - ASTM F2077 Test methods for intervertebral body fusion devices;

The ASTM F2077 test method covers the materials and methods for the static and dynamic fatigue testing of intervertebral body fusion devices, spinal implants that are designed to promote arthrodesis at a given spinal motion segment. Intervertebral body fusion cages are among this implant type.

ASTM F2077 Intervertebral body fusion devices tests include:

Axial-Compression

Compression-Shear

Torsion Testing

The standard specifies the testing materials and methods for interbody fusion devices used to promote fusion in a specific spinal segment, aimed at establishing standard principles for the comparison of mechanical properties of non-biological interbody fusion devices. A torsional fatigue test was conducted on the samples at a frequency of 5Hz, R=-1, for 5 million cycles or until sample failure.
