Systems and methods for vertebral or other bone structure height restoration and stabilization

1. A method for stabilizing a fractured bone structure of a patient, the fractured bone structure having a fractured height, the method comprising:

expanding the bone structure to a restored height greater than the fractured height by transitioning at least a first expandable member inserted into the bone structure from a contracted state to an expanded state;

delivering a curable material into a first cavity formed in the bone structure while the first expandable member maintains the bone structure at the restored height;

allowing the curable material to harden while the first expandable member maintains the bone structure at the restored height; and

after the curable material has hardened, removing the first expandable member from the bone structure.

2. The method of claim 1 , wherein the bone structure is a vertebra.

3. The method of claim 1 , wherein a second cavity is defined in the bone structure following removal of the first expandable member, the method further comprising:

delivering a curable material into the second cavity.

4. The method of claim 1 , wherein the step of expanding the bone structure further includes transitioning a second expandable member inserted into the bone structure from a contracted state to an expanded state.

5. The method of claim 4 , wherein the first and second expandable members are balloons.

6. The method of claim 1 , wherein the first expandable member includes a balloon exteriorly coated with anti-sticking material.

7. The method of claim 1 , wherein the step of delivering a curable material includes a portion of the curable material coming into contact with the first expandable member, and the step of allowing the curable material to harden includes the portion of the curable material in contact with the first expandable member not bonding to the first expandable member.
