A method of compacting and stabilizing bone in the spine using an expandable screw and bone filler. The method comprises placing an expanding screw through a pedicle and into a fractured vertebral body using established techniques and expanding the screw within the body to create a cavity by tamping bone around the expanded aspect of the screw. The screw can be expanded and rotated about its rotational-axis to tamp bone adjacent to the expanded screw. After compaction, the screw is removed and the cavity is filled with bone filler.
