a non-resorbable, structural framework having top and bottom bone-contacting surfaces and a plurality of support columns extending between proximal and distal ends of the structural framework, the plurality of support columns being spaced apart from each other to define vertical openings in the framework, the structural framework including at least one keyed opening;

a resorbable material component within and/or around the framework for resorption and formation of new bone to fuse the vertebral bodies together, at least a portion of the structural framework being interposed between the resorbable material component, the resorbable material component having top and bottom bone-contacting surfaces arranged to contact vertebral endplates over a contact surface area sufficient to reduce peak stresses between the structural framework and the vertebral bodies to reduce or eliminate subsidence of the structural framework into the vertebral bodies, and

at least one bone anchor received in the at least one keyed opening to secure the bone anchor to the implant.
