Abstract
Precision recesses are cut in the end plates of vertebral bodies by inserting into the disc space a cutter having a pair of shell elements provided with cutting edges shaped to match bone growth apertures in a selected prosthesis. The remainder of the end plates are left undisrupted, to maximize bearing strength while promoting bone growth at the apertures.
