Abstract
An instrument set 120 and method for preparing a site between adjacent bones for insertion of an implant includes an alignment probe 122 with a head end 124 and a cutter 134 which fits over the alignment probe 122. The alignment probe 122 can be appropriately positioned using imaging techniques and then given a quarter turn in order to anchor the head end 124 in the bones at the appropriate depth and with the appropriate alignment. The cutter 134 is then inserted over the alignment probe 122 in order to sever bone and tissue. After this is accomplished, the head end 124 is given another quarter turn freeing itself from the bone, and then the alignment probe 122 and the cutter 134 are removed with the tissue and bone captured therebetween.
