Abstract
Alignment devices for promoting spinal fusion between neighboring vertebrae are disclosed. The alignment device may be use to alter the vertical height between the engaging plates to customize the apparatus to fit a given patient. In one embodiment, the alignment device includes two turnbuckles and two pairs of cam blocks for adjusting the height between a pair of engaging plates. The alignment device may be adapted to vary the height between the engaging plates such that the height of the apparatus proximate a first side edge is substantially different from a height of the apparatus proximate a second side edge.
