Methods for treating a fractured and/or diseased and/or weakened bone

1. A method comprising

establishing a percutaneous path into a vertebral body having cortical bone enclosing a cancellous bone volume,

forming a cavity in the cancellous bone volume,

compressing at least a portion of the cancellous bone volume by injecting a pressurized flowable bone filler material directly into the cavity,

pushing the flowable bone filler material outward against the walls of the cavity to increase the size of the cavity by injecting additional flowable bone filler material into the cavity; and

moving a fractured cortical bone of the vertebral body to a pre-fractured position by injecting additional flowable bone filler material into the cavity.

2. A method according to claim 1 , wherein the flowable bone filler material comprises a bone cement.

3. A method according to claim 1 , wherein the bone filler material comprises a bone cement.

4. A method of claim 1 , wherein the flowable bone filler material comprises a bone cement.

5. A method comprising

establishing a percutaneous path into a bone structure having cortical bone enclosing a cancellous bone volume,

introducing a flowable bone filler material directly into at least a portion of the cancellous bone volume,

pressurizing the flowable bone filler material within the bone structure by continuing the introduction of the flowable bone filler material into the cancellous bone volume,

compressing the cancellous bone volume within the bone structure by the pressurizing of the flowable bone filler material; and

moving a fractured cortical bone of the vertebral body to a pre-fractured position by injecting additional flowable bone filler material into the cavity.

6. A method according to claim 5 wherein the pressurizing of the flowable bone filler material within the bone structure moves fractured cortical bone.

7. A method according to claim 5 wherein the bone structure comprises a vertebral body.

8. A method according to claim 5 wherein the flowable bone filler material comprises a bone cement.

9. A method according to claim 5 , wherein the flowable bone filler material comprises at least one of a bone filler, a bone cement, a synthetic bone substitute, a bone biomaterial, a hydroxyapatite material, a bone mineral material, a thixotropic material, a curable biomaterial, allograft tissue, and autograft tissue.

10. A method comprising

creating a cavity a vertebral body,

introducing a first amount of a flowable bone filler material directly into the cavity,

introducing a second amount of pressurized flowable bone filler material into the cavity such that the flowable bone filler material pushes outward against a wall of the cavity, thereby compressing a cancellous bone in the vertebral body and increasing the size of the cavity; and

moving the cortical bone until the fractured cortical bone regains a pre-fractured position.

11. A method according to claim 9 wherein introducing the second amount of the flowable bone filler material moves fractured cortical bone of the vertebral body.

12. A method comprising

compressing at least a portion of a cancellous bone volume within a vertebral body by injecting a flowable bone filler material directly into the cancellous bone volume,

moving fractured cortical bone of the vertebral body by injecting pressurized flowable bone filler material into the vertebral body,

comprising moving fractured cortical bone to a pre-fractured position.

13. A method according to claim 12 wherein the flowable bone filler comprises a bone cement.

14. A method according to claim 12 , wherein the flowable bone filler material comprises at least one of a bone filler, a bone cement, a synthetic bone substitute, a bone biomaterial, a hydroxyapatite material, a bone mineral material, a thixotropic material, a curable biomaterial, allograft tissue, and autograft tissue.
