Patent ID: 8303660

Claim:
An orthopedic implant configured to be positioned within an intervertebral disc space between a first vertebral bone and an adjacent second vertebral bone, comprising: a first implant member configured to extend along a longitudinal axis from an anterior surface to a posterior end, the first implant member comprising a bone abutment surface configured to abut a surface of the first vertebral bone, and a first bearing configured to articulate with a bearing surface of a second implant member; an elongated member configured to extend posteriorly from an aperture of the anterior surface of the first implant member and in the direction of the longitudinal axis, the elongated member being coupled to a proximal aspect of at least one bone fixation member, the bone fixation member configured to extend to a distal segment along a first axis and configured to rotate in a curvilinear trajectory that is centered about the longitudinal axis, the first axis comprising a different axis than the longitudinal axis; a bone fixation member comprising a distal end configured to project from a distal aspect in a direction of a tangent to the curvilinear trajectory, the distal end being further configured to advance into the first vertebral bone when rotated in a direction of the distal end, and the rotated bone fixation member being separated from simultaneous anchor into each of the first and the second vertebral bones; and a second implant member comprising a bone abutment surface configured to abut a surface of the second vertebral bone, and a first bearing configured to articulate with the first bearing surface of the first implant member; wherein the articulation maintains motion between the first and second vertebral bones.
