Claim:
1. An intervertebral fusion device comprising: a first component having i) a proximal component end, ii) a distal component end opposite the proximal component end along a proximal-distal direction, iii) a first outer surface that extends between the proximal and distal component ends, and is positioned and configured to contact a vertebral endplate, iv) a through hole that extends through the first outer surface and adapted to promote vertebral fusion through the first component, and v) a first translation surface extending between the proximal component end and the distal component end and oriented at an oblique angle to the first outer surface; a rail component having i) a proximal rail end, ii) a distal rail end, iii) a second outer surface that extends between the proximal and distal rail ends, iv) a hole extending distally from an opening in the proximal rail end, and v) a second translation surface that is oriented at an oblique angle to the second outer surface; and a threaded screw disposed within the hole of the rail component, wherein the first and second outer surfaces are configured to be substantially coplanar with each other when the rail component is movable with respect to the first component along the proximal-distal direction so as to cause the first and second translation surfaces to translate upon each other.
