A chisel guide (50), for use with the cutting guide (20), includes a first block member (54) adjacent the vertebral body. The chisel guide (50) also includes a second block member (52) connected to the first block member (54). An apparatus for creating a cavity in a vertebral body endplate and in an intervertebral disc may be a compressor (160) or a distractor (500) having at least one cutting implement thereon.
