Fig. 3From: Biomechanical effects of an oblique lumbar interbody fusion combined with posterior augmentation: a finite element analysisComparison of experimental results among all models. Comparisons of a range of motion, b L4 superior endplate stress, and c posterior instrumentation stress for the intact model and surgical procedures. ROM, range of motion; Intact, intact model; SA, stand-alone; PSR, pedicle screw and rod; CSR, cortical screw and rodBack to article page
