Abstract
Abstract A variable position bone drilling guide apparatus for aiding a surgeon in preparing a bone site. The guide apparatus includes a template that is formed to include apertures therethrough and drill towers extending form the template in general alignment with the apertures. The first drill tower includes at least one drill passage therethrough and the second drill tower includes two drill passages therethrough. The duel passages in the second tower provide a surgeon with greater than one drill alignment option for a bone plate.
