Abstract
Instruments for inserting an implant in a space between adjacent bony portions include upper and lower guide members separated by a spreader with the implant positioned forwardly of the spreader. The spreader is movable forwardly between the guide members with a drive member to position the implant in a space between the bony portions. The spreader contacts the adjacent bony portions to facilitate withdrawal of the inserter instrument when the implant is positioned in the space.
