Abstract
Tools for use in the creation of cavities in bones. The tools include a probe, a cannula that provides percutaneous passageway to the interior of the treated bone, a bone tamp, and a system for delivering bone filler material into the cavity. The bone tamp has a shaft that is inserted into the bone through the cannula. The end of the shaft that is inserted into the bone may have a flapper tip that extends out of axial alignment with the shaft upon deployment by the physician. Once the tip is deployed, the bone tamp can be rotated to form the cavity. The cavity may then be treated with a medicament, filled with bone filler material, or both. Other tools and materials described herein may be used to lift or restore the treated bone closer to its natural anatomy.
