Figure Legend:
Fracture pattern per simulation. Simulations that lied within the final domain of solution (gray area) resulted in superior endplate fractures of L3 (•), as observed experimentally. Other simulations either resulted in superior endplate fractures of L3 (•), vertebral body collapse of L2 (▴) or inferior endplate fracture of L2 (▪).

Figure Legend:
Simulated load-displacement curves versus experimental corridor. Simulations #10 and #21 used calibrated material constants (C10-Annulus and C10-Nucleus within the final domain of solution) while simulation #35 used material constants derived from quasi-static experiments [].
