LEARNING OBJECTIVES To evaluate and determine whether the hypothesis is true Test a mock Interbody fusion device in static axial compression testing, static compressive shear testing and static torsion testing in a constrained test setup, a semi-constrained test setup and an unconstrained test setup per ASTM F2077. Null Hypothesis: There is no difference between the mechanical performance of static axial compression testing, compressive shear testing and torsion testing in a constrained test setup, a semi-constrained test setup and unconstrained test setup per ASTM F2077 Click here to download full study
