FE model of the lumbar spine. a (1) Intact model (L1–S1). Frontal and lateral view of the whole lumbar spine with a schematic representation of the boundary and loading conditions and the ligaments [antero-longitudinal ligament (ALL); postero-longitudinal ligament (PLL); intertransverse ligament (ITL); interspinous ligament (ISL); capsular ligaments (JC); flaval ligament (FL); supraspinous ligament (SSL)] (left). Top view of L5 and the disc between L4–L5 (right). b Stand-alone models. Two different cages were introduced in the L4–L5 interbody space: (2) OLYS cage and (3) NEOLIF cage. A lateral view of the whole lumbar spine and the top view of cages placement are shown. c Cage + PSF models. The stand-alone models have been supplemented with PSF after the perforation of L4 and L5 vertebrae: (4) OLYS + PSF and (5) NEOLIF + PSF
