Abstract
A vertebral body replacement or spacer that re-creates a lordosis angle (or other angle) of a human spine. An embodiment of the spacer may comprise contoured superior and inferior bearing surfaces. More particularly, the contoured surfaces may be defined by compound curves such as two radii substantially orthogonal to each other. As a result, the bearing surfaces may conform to the convex end plates of adjacent vertebra. In another embodiment, the present invention may provide a method of establishing a lordosis angle. The method may comprise inserting a spacer into an intervertebral space and positioning the spacer in such a manner that the contoured surfaces generally correspond to the end plates of the adjacent vertebra. However, the spacers and methods of the embodiments of the present invention may be used to re-create other angles in the human spine.
