1. 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 interdigitate 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.
