ASTM F2346: Standard Test Methods for Static and Dynamic Characterization of Spinal Artificial Discs
These test methods specify the materials and methods for the static and dynamic testing of artificial intervertebral discs.
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.
The load blocks are prepared in advance to match the geometry of the cage. The load blocks can either be designed based on CAD data of the cages provided by the client, or the cages can be digitally captured at EndoLab® using a high-resolution 3D scanner.
