1-50. (canceled)
A vertebral replacement device, comprising:
- a connecting member including a body and first and second threaded extensions extending from said body along a longitudinal axis;
- a first member threadingly engageable to said first threaded extension, wherein said first member includes a body extending between a first end and a second end, said body including a height between said first and second ends and adapted to restore a spinal disc space when said first member is positioned therein;
- and
- a second member threadingly engageable to said second threaded extension, wherein said second member includes a body extending between a first end and a second end, said body having a height between said first and second ends and adapted to restore a spinal disc space when said second member is positioned therein,
- wherein at least one of said first and second members includes first and second ends that are each sloped relative to a longitudinal axis of the vertebral replacement device, and wherein at least one of said first and second members includes an outer surface defining a kidney-shaped cross-section extending between said first and second ends thereof.
