Abstract
A method for stabilizing a bone structure including directing first and second expandable members in contracted state to a first location within the bone structure. The expandable members are expanded, forming first and second cavities within the bone structure. The first expandable member is then transitioned back to the contracted state while maintaining the second expandable member in the expanded state. The first expandable member is removed, and curable material delivered into the first cavity. The second expandable structure is contracted and removed. A curable material is delivered into the second cavity. A height of the bone structure is restored via expansion of the two expandable members, and is retained throughout the procedure first by the second expandable member during delivery of curable material into the first cavity, and then by the hardened material in the first cavity during removal of the second expandable member.
