Patent ID: 7618439

Claim:
An intervertebral disc replacement assembly for replacing at least portions of at least two intervertebral discs in a spinal column, comprising: a first member having a first vertebral contact surface, a first articulation surface, and a first flange including a first through hole for receiving a bone screw for fastening the first member to a first vertebral bone of a spinal column, and a first fastener hole; a first intermediate member having a first intermediate vertebral contact surface, a first intermediate articulation surface, and a first intermediate flange including a second fastener hole offset from the first fastener hole of the first member, the entirety of the first intermediate flange offset to one side of a midline of the assembly, the first intermediate vertebral contact surface being operable to contact an endplate of an intermediate vertebral bone adjacent to the first vertebral bone of the spinal column, the first articulation surface and the first intermediate articulation surface cooperating to facilitate articulation of adjacent vertebral bones of the intervertebral disc space when the intervertebral disc replacement device is disposed in the intervertebral disc space; and a first insertion plate for engaging the first member and the first intermediate member, the first insertion plate cooperating to orient the first articulation surface and the first intermediate articulation surface in substantial registration with one another for simultaneous insertion into the intervertebral disc space, wherein the first and second fastener holes of the first flange and the first intermediate flange are sized and positioned to receive at least one fastener operable to couple to the first insertion plate thereto such that the first member and the first intermediate member are oriented in registration with one another for simultaneous insertion into a first intervertebral disc space defined by respective endplates of the first and intermediate vertebral bones.
