ABSTRACT:
A unitary instrument for providing a step-down screw hole in a pedicle is provided. The tool includes an end member for rotatable connection with a power source, the probe for providing a pilot hole in the pedicle and a side-cutting reamer member for providing an anchor hole for a pedicle screw positioned about the pilot hole. The arrangement is such that the instrument is self-centering in part due to the presence of the probe in the pilot hole.
