2. A method of treating a vertebral body having a superior endplate and an inferior endplate, comprising the steps of:
-
inserting a container into a vertebral body;
deploying said container within said vertebral body;
injecting a bone filler material selected from the group of;
bone cement;
human bone graft allograft;
human bone graft autograft;
synthetic derived bone substitute;
sulfate and/or calcium phosphate, hydroxyapatite;
into said container under pressure;
whereby said pressure supplies a distraction force to move said inferior and superior endplates apart;
ending injection after said endplates have moved apart.

4. A method of treating an vertebral body comprising the steps of:
-
inserting a container into an vertebral body;
said container having a fill passage coupled to said container;
said container having a porous outer membrane sufficiently porous to allow filler material under pressure to leave the container after filling the container;
deploying said container within said vertebral body injecting a filler material into said container through said fill passage with bone filler material in a sufficient volume to allow the bone filler material to exit the container and interdigitates with cancellous bone within said vertebral body thereby reinforcing said bone and stabilizing fractures in said bone;
said container membrane porosity sufficient to provide resistance to the flow of said bone filler material to generate force to move the endplates of said vertebral body. - View Dependent Claims (5)
