An intervertebral implant may include an expandable implant including a superior endplate and an inferior endplate. Each of the endplates may include a first portion having a solid structure and a second portion having a porosity. The first portion comprises a plurality of transverse struts having voids located between the struts and the second portion comprises a lattice structure formed in the voids. A bone funnel assembly may be used to inject graft material into the implant.
