Composite interbody device and associated manufacturing method

Abstract

A composite interbody device includes (a) a plastic core having a superior surface and an inferior surface, (b) a superior endplate and (c) an inferior endplate. Each of the superior and inferior endplates includes (i) a bone interface side for interfacing with bone and having a plurality of pores permitting bone growth therein, and (ii) a core interface side, opposite the bone interface side, having a plurality of voids that accommodate material of the plastic core to couple the endplate to a respective one of the superior and inferior surfaces, wherein the voids are isolated from the pores to prevent the material of the plastic core from entering the pores.

Dependencies are inferred from the claim text.
