Median percent error for FE-computed axial displacements compared to the measured displacements, for the CF and VM yield criteria and both loading modes. For both loading modes and both yield criteria, the median percent errors were lower for the Experimental Matched vs. all other boundary conditions (* p < 0.001). For flexion loading and both yield criteria, the errors were lower for the IVD-Generic vs. Idealized boundary condition (# p = 0.004).
