8. A prosthetic disc assembly comprising:
a first vertebral plate including a first endplate surface configured to engage an endplate of a first vertebral body and a first internal surface opposite the first endplate surface;
a second vertebral plate including a second endplate surface configured to engage an endplate of a second vertebral body and a second internal surface opposite the second endplate surface, each of the first and second vertebral plates further including one or more guide openings;
a core disposed between the first vertebral plate and the second vertebral plate configured to enable relative movement between the first vertebral plate and the second vertebral plate, wherein the first internal surface is curved to enable pivoting of the first vertebral plate relative to the second vertebral plate and wherein the core includes a planar surface configured to translate or rotate on the second internal surface of the second vertebral plate; and
a plurality of bone anchors configured to couple the first and second vertebral plates to the first and second vertebral bodies upon implantation using the one or more guide openings, wherein leading peripheral edges of the first and second endplate surfaces each comprise an exteriorly facing bevel to facilitate insertion of the implant between the first and second vertebral bodies and wherein trailing peripheral edges of each of the first and second endplate surfaces are unbeveled, wherein each bone anchor of the plurality of bone anchors are respectively positioned between a corresponding one of the first and second endplate surfaces of the first and second vertebral plates, respectively, and a corresponding endplate surface of a corresponding one of the first and second vertebral bodies when the prosthetic disc assembly is inserted between the first and second vertebral bodies, and wherein each bone anchor of the plurality of bone anchors is inserted with the first vertebral plate and the second vertebral plate.
