1. A structure for use in medical implants, the structure comprising:
a three-dimensional lattice structure configured to extend between two adjacent bony structures and provide sole mechanical spacing between the two adjacent bony structures, the three-dimensional lattice comprising:
a plurality of repeating unit cells; and
a plurality of fluidly interconnected openings disposed within a volume of the three-dimensional lattice, the plurality of fluidly interconnected openings comprising a first group of openings comprising a first width and a second group of openings comprising a second width, the second width being greater than the first width and number of openings in the second group of openings being a ratio of about 1:1 to 1:25 of number of openings in the first group of openings.
