ASTM F2077: Test Methods For Intervertebral Body Fusion Devices
This test method describes the materials and methods for testing of intervertebral body fusion device assemblies, spinal implants designed to promote arthrodesis at a given spinal motion segment. Depending on the intended spinal location, the devices are tested in static and dynamic axial compression, shear compression and/or torsion mode. For testing, the implants are inserted between polyacetal test blocks for dynamic loading or stainless steel blocks for static loading.
TEST SYSTEM
An axial-torsion system is required to encompass all test types from this standard and will allow manufacturers and researchers to conduct both static and fatigue testing on a range of implant designs with a single test system. The HST-EFT-A Electric Dynamic Test Instruments, as well as the HFT-TA servohydraulic Dynamic test frame, all offer the necessary capabilities for testing to this standard with the use of specialised fixtures.Relate Products
