Materials: Biomedical, Biomaterials
Standard: ASTM F2077
Intervertebral Body Fusion devices are used to promote arthrodesis of a spinal motion segment, following disc degeneration. The implant acts as a support of the anterior column whilst the two vertebral discs grow together and fuse the spine. Intervertebral Body Fusion is an alternative technique to that of Intervertebral Disc replacement.

The tests include:Axial-Compression, Compression-Shear, Torsion Testing
We recommend that you review the standard to fully understand its requirements. An alternative test for intervertebral body fusion devices is specified in ASTM-F2267.

Challenges of ASTM F2077 Testing:
Machining/manufacture of test blocks to match specimen shape
Monitoring of intradiscal height during test
Assessment of mechanical failure during test
Avoidance of self-heating in test blocks
Maintaining load peaks at high frequency
Test duration for in vivo tests
