摘要：
The present invention relates to an intervertebral disc replacement assembly (1350) comprising:
a first member (1500) having a first vertebral contact surface for contacting a first vertebral body, a first bearing surface, and a first flange (1506) including a first hole;
a second member (1600) having a second vertebral contact surface for contacting a second vertebral body, a second bearing surface cooperating with the first bearing surface to facilitate articulation of the first and second vertebral bodies with respect to one another, and a second flange (1606) including a second hole (1609),
a third member (2500) having a third vertebral contact surface for contacting the second vertebral body, a third bearing surface, and a third flange (2506) including a third hole (2509); and
a fourth member (2600) having a fourth vertebral contact surface for contacting a third vertebral body, a fourth bearing surface cooperating with the third bearing surface to facilitate articulation of the second and third vertebral bodies with respect to one another, and a fourth flange (2606) including a fourth hole,
wherein the entirety of the second flange (1606) is offset to a first side of a midline of the assembly (1350), and the entirety of the third flange (2506) is offset to a second side of the midline of the assembly (1350).
