Abstract
A spinal fusion bone scaffold having a first member including a first base plate and a first plurality of struts each having a first end engaging the first base plate and a second, free end. The first plurality of struts is configured to form at least part of a hyperbolic curve such that said bone scaffold includes an overall optimized hyperboloid shape having an outer diameter and an inner waist diameter. The scaffold may include a second member including a second plurality of struts each having a first end and a second end, each of the second plurality of struts being configured to form at least part of the hyperbolic curve. The scaffold includes connecting means for connecting said second member to said first member, which are aligned so as to complete the hyperbolic curve while generating hyperboloid geometry of the bone scaffold.
