Abstract
A prosthetic device for insertion into a spondylosed intervertebral space is provided. The prosthetic device includes a first component having a first flange for longitudinally engaging a first vertebra during longitudinal insertion therein, and a second component having a second flange for longitudinally engaging a second vertebra during longitudinal insertion therein. One of the first and second components comprises a projection and the other of the first and second components comprises a recess, the projection and recess being adapted to engage one another. One of the projection and the recess are offset relative to the other of the projection and the recess to accommodate the spondylosed relationship between the first and second vertebrae.
