Abstract
A method for postoperatively compressing a bone graft between adjacent spinal vertebrae utilizing first and second plates having openings at remote ends for receiving bone screws to fix the plates to respective vertebrae on opposite sides of a bone graft-receiving site. The first and second plates have male and female parts having interlocking elements cooperable with one another enabling movement of the plates and the adjacent vertebrae to one another to progressively compress the bone graft between the adjacent vertebrae and prevent movement of the first and second plates and adjacent vertebrae away from one another.

A method for postoperatively compressing a bone graft between adjacent spinal vertebrae comprising the steps of:
- securing a first plate of a spinal fixation device to a vertebra adjacent one side of a bone graft;
- securing a second plate of the spinal fixation device to a vertebra adjacent an opposite side of the bone graft;
- releasably interlocking said first and second plates in a first position relative to one another;
- postoperatively advancing the plates from said first position toward one another into a second position relative to one another in response to movement of the vertebrae toward one another;
- and
- locking the plates to one another in said second advanced position from said first position precluding movement of the plates away from one another to maintain the bone graft between the adjacent vertebrae under compression.
