1. A method for treating bone after high velocity and/or trauma fracture comprising the steps of:
- inserting an insertion device percutaneously into a vertebral body;
inserting a cavity-forming device through the insertion device into an area of cancellous bone in the vertebral body;
displacing cancellous bone with the cavity-forming device to create a cavity and a barrier region of compressed cancellous bone substantially surrounding the cavity; and
filling at least a portion of the cavity with a bone filler.

12. A method for treating bone after high velocity and/or trauma fracture comprising the steps of:
-
inserting a spinal needle of a needle assembly percutaneously through a pedicle into a vertebral body;
inserting a balloon catheter through the spinal needle into an area of cancellous bone within the vertebral body, so that the distal end of the balloon catheter extends out of the distal end of the spinal needle;
inflating the balloon catheter with an inflation medium such that inflation of the distal end of the balloon catheter extending from the spinal needle displaces cancellous bone around the inflating balloon, forming a barrier around the balloon catheter that at least partly closes large cracks or veins within the cancellous bone area of the vertebral body;
deflating the balloon catheter and leaving a cavity within the cancellous bone area of the vertebral body;
removing the balloon catheter from the vertebral body through the needle assembly; and
filling the cavity with a bone filler. - View Dependent Claims (13, 14)

15. A system for treating bone after high velocity and/or trauma fracture comprising
an insertion device sized and configured to be inserted percutaneously into a vertebral body; -
a cavity-forming device sized and configured to be inserted through the insertion device into an area of cancellous bone in the vertebral body to displace cancellous bone and create a cavity; and
a bone filler including calcium phosphate for filling at least a portion of the cavity.
