1. An implant comprising:
a pair of endplates having a posterior surface, an anterior surface, and opposing sides, wherein the pair of endplates are movably attached to one another by a sliding dovetail joint located on the posterior surface of the implant, and further wherein a range of motion of the pair of endplates at the posterior surface is less than a second range of motion of the pair of endplates at the anterior surface;
at least one structurally encoded member; and
a wedge component positioned at least partially between said pair of endplates, wherein the positioning of the wedge component modifies the height and lordotic angle of the implant.
