Testing for Occipital-Cervical and Occipital-Cervical-Thoracic Spinal Implants in a Vertebrectomy Model
This standard includes three static test methods (compression bending, tensile bending, and torsion) and two dynamic test methods (compression bending fatigue and torsion fatigue) that may be applied to occipital-cervical and occipital-cervical-thoracic spinal implant constructs. The spinal implant construct may include bone screws, rods, set screws, hooks, transverse elements, cables, wires, and/or bolts. The spinal implant construct is assembled into specified test blocks to simulate a vertebrectomy model. Spinal implant assemblies are tested accordingly to determine their yield load, stiffness, and strength. Fatigue tests shall reach a run-out of 5 million cycles or failure.
