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.

The following tests are described:

• Static and dynamic compression test
• Static and dynamic compression-shear test
• Static and dynamic torsion test
