Abstract
A vertebral replacement device for supporting adjacent vertebrae includes a vertebral body or vertebral body member having at least one of an upper or lower member adjustably engaged at one end thereof. A spacer can be engaged to the upper or lower member to further increase the height of the vertebral replacement device. The vertebral replacement device can have a chamber extending therethrough for fusion of the supported vertebrae.
Claims20
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.

- a connecting member including a body and a first threaded extension extending from said body along a longitudinal axis;
- and
- 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, wherein said first and second ends are sloped toward one another and are each sloped relative to said longitudinal axis, wherein said first member includes an outer surface defining a kidney-shaped cross-section extending from said first sloped end to said second sloped end of said body of said first member.
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, said body including an outer surface defining a circular cross-section;
- and
- 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, wherein said first and second ends are each sloped relative to said longitudinal axis and said body includes an outer surface defining a kidney shaped cross-section extending from said first sloped end to said second sloped end.
