Abstract
An instrument set 20 and method for preparing a site between adjacent bones for insertion of an implant includes an alignment probe 22 with a head end 24 and a cutter 34 which fits over the alignment probe 22. The alignment probe 22 can be appropriately positioned using imaging techniques and then given a quarter turn in order to anchor the head end 24 in the bones at the appropriate depth and with the appropriate alignment. The cutter 34 is then inserted over the alignment probe 22 in order to sever bone and tissue. After this is accomplished, the head end 24 is given another quarter turn freeing itself from the bone, and then the alignment probe 22 and the cutter 34 are removed with the tissue and bone captured therebetween.
