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 (▪).
