Abstract:
1. A method for enhancing an interbody device, comprising: securing a superior endplate having a porous bone interface surface to a superior surface of a preexisting interbody device, on a side opposite the bone interface surface; and securing an inferior endplate having a porous bone interface surface to an inferior surface of the device, on a side opposite the bone interface surface; each of the superior and inferior endplates comprising a central barrier layer and a porous device interface surface; wherein securing the endplates to the device comprises applying the endplates to the interbody device as a composite coating; and wherein securing each endplate to the device comprises applying a bonding agent to one or both of (a) the porous device interface surface and (b) the surface of the interbody device, the central barrier layer preventing diffusion of the bonding agent into the bone interface side.
