Static and Fatigue Testing of Interconnections and Subassemblies in Spinal Arthrodesis Implants
Describes test methods to evaluate uniaxial static strength, fatigue strength and resistance to loosening of interconnection mechanisms of spinal arthrodesis implants. Mechanical static testing is performed to failure and fatigue testing is performed for components to a maximum of 2.5 million cycles. Load is applied to interconnections in relevant directions as outlined by the ASTM standard.
