The human ligamentous lumbar spine was modelled in the frontal plane as an Euler column for the purpose of rigorously studying its mechanical stability. Using stiffness data obtained from testing cadaveric specimens, we simulated the vertebral bodies as rigid links and the intervertebral elastic behaviour as both linear (linear model) and exponential (exponential model). The linear model, with a higher initial stiffness, predicted a higher buckling load (67 N), and hence was more stable in… CONTINUE READING
