Theoretical model used as the basis for the beam-on-elastic-foundation analysis. A composite of the disc/PMMA and endplate was considered as the beam, and the trabecular bone was considered as the foundation. The properties of the beam and the foundation were based on mean values of the measurements for the 22 vertebral bodies used in our finite element analysis: d = 5.5 mm (endplate thickness 0.5 mm (Fields et al., 2010)); L = 26 mm; depth (into page) b = 28 mm; and the effective height of the elastic foundation H = 28 mm.
