Abstract

Osteogenesis scaffold such as for spinal fusion or an intermedullary nail includes a number of arcuate struts. The scaffold may have a functional modulus of elasticity that is a result of the modulus of the material of the struts together with the architecture of the struts, and may be within the range of 5 GPa and 75 GPa. An anisotropy of a physical property such as stiffness, compressive strength or elastic modulus corresponds to the same physical property of native bone in the vicinity of the intended implantation site.

Claims

1. An osteogenesis scaffold configured for spinal fusion, comprising:

a superior support surface;

an inferior support surface;

a plurality of arcuate struts separating the superior and inferior support surfaces, the struts comprising a material having a strut modulus;

the scaffold having a functional modulus which is different than the strut modulus and is the result of the strut modulus and the architecture of the implant.
