1. An interbody fusion device comprising top and bottom endplates, first and second lateral sides, anterior and posterior ends, and a body; said body positioned between said top and bottom endplates, said first and second lateral sides, and said anterior and posterior ends; each of said top and bottom endplates configured to interface or engage with bone when said interbody fusion device is positioned between adjacent vertebra of a spine; said body includes a body cavity; said first lateral side includes a plurality of first lateral openings that terminate in said body cavity; said second lateral side includes a plurality of second lateral openings that terminate in said body cavity; cavity; said posterior end includes a first posterior opening that terminates in said body cavity; said anterior end absent an opening that terminates in said body cavity; said top endplate is formed of a top lattice structure and a top frame surrounding said top lattice structure; said bottom endplate is formed of a bottom lattice structure and a bottom frame surrounding said bottom lattice structure; said top lattice structure on said top endplate forming a plurality of top openings that terminate in said body cavity; said bottom lattice structure on said bottom endplate forming a plurality of bottom openings that terminate in said body cavity; said top frame of said top endplate includes a top micro-aperture region that fully encircles said top lattice structure; said top micro-aperture region includes a plurality of top micro-apertures having an average size of 2-10 micrometers (μm) and a plurality of top macro-apertures having an average size of 300-800 micrometers (μm); one or more of said top micro-apertures terminating in said body cavity; one or more of said top macro-apertures terminating in said body cavity; each of said top openings has a size that is greater than each of said top micro-apertures and each of said top macro-apertures; said bottom frame of said bottom endplate includes a bottom micro-aperture region that fully encircles said bottom lattice structure; said bottom micro-aperture region includes a plurality of bottom micro-apertures having an average size of 2-10 micrometers (μm) and a plurality of bottom macro-apertures having an average size of 300-800 micrometers (μm); one or more of said bottom micro-apertures terminating in said body cavity; one or more of said bottom macro-apertures terminating in said body cavity; each of said bottom openings has a size that is greater than each of said bottom micro-apertures and each of said bottom macro-apertures.
