ASTM F1717: Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model.

These test methods cover the materials and methods for the static and fatigue testing of spinal implant assemblies in a vertebrectomy model. The appropriate tests within the standard have to be selected depending on the implant system and its intended spinal location and application method.

Static and dynamic loading is performed for the worst-case scenario. Load transfer between the resection lines has to be guaranteed by the implant without bone support. Two UHMWPE blocks are used for implant fixation. The dynamic loading is performed at a frequency of 5 Hz and at up to 5 million cycles. In general, six specimens are tested. Regular tests are performed in air at room temperature. The implant material may require test setups simulating body environmental conditions at 37 °C in saline solution.
The standard describes the following test procedures: Static and dynamic axial compression bending, static tension bending, and static torsion. This standard is applicable to lumbar and cervical systems.
