Method and apparatus for promoting a spinal fusion between neighboring vertebrae. The apparatus may be located in an intervertebral disc space and the apparatus preferably includes a pair of engaging plates for contacting the vertebrae. An alignment device of the apparatus may be used to alter the vertical distance between the engaging plates to customize the apparatus to fit a given patient. In an embodiment, the alignment device includes a rotatable connector and cam pins for adjusting the distance between the engaging plates. The alignment device is preferably adapted to vary the distance between the engaging plates such that the height of the apparatus proximate the anterior end is greater than the height of the apparatus proximate the posterior end whereby the natural lordosis of the spine is maintained after the apparatus is installed. The apparatus may further include a load-sharing member to allow stress to be imparted to bone in the vicinity of the apparatus to promote bone growth in accordance with Wolff's law.
