Test Methods for Spinal Implant Constructs in a Vertebrectomy Model
Describes static and fatigue testing of spinal implant assemblies in a vertebrectomy model which is simulated with a large gap between two UHMWPE test blocks adjoined by the implant assembly. Compression bending, tensile bending, torsion testing, and compression bending fatigue test methods are provided as well as guidelines for measuring displacements, determining yield load and evaluating stiffness and strength of the spinal implant assembly.
