Claim 17:
18. An intervertebral implant comprising:
a first plate including a first bone contacting surface configured to contact an endplate of a first vertebral body and a first articulation surface opposite the first bone contacting surface, the first plate further including a first elongated osseous anchorage member extending between opposing trailing and leading peripheral edges and along a longitudinal axis of the first plate and configured to anchor the first plate into the first vertebral body;
a second plate including a second bone contacting surface configured to contact an endplate of a second vertebral body and a second articulation surface opposite the second bone contacting surface, the second plate further including a second elongated osseous anchorage member extending between opposing trailing and leading peripheral edges and along a longitudinal axis of the second plate and configured to anchor the second plate into the second vertebral body; and
a core disposed between the first plate and the second plate configured to enable relative movement between the first plate and the second plate, wherein one or more of the leading peripheral edges of the first and second bone contacting surfaces comprises a bevel to facilitate insertion of the intervertebral implant between the first and second vertebral bodies, wherein one or more of the trailing peripheral edges of the first and second bone contacting surfaces is unbeveled, and wherein only a portion of one or more side peripheral edges of the first and second bone contacting surfaces comprises the bevel with a remaining portion of the one or more side peripheral edges being unbeveled,
wherein translation of the core relative to the second plate is restricted by engagement of pairs of male and female members,
wherein the male members are located on sided edges of the core and the female members are located on the second plate, and
wherein each of the male members is slightly smaller than an engaging female member to allow slight travel between the core and the second plate.
