Abstract

A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.
