Abstract
Abstract The invention provides a method of correcting numerous bone abnormalities including bone tumors and cysts, avascular necrosis of the femoral head, tibial plateau fractures and compression fractures of the spine. The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and/or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and/or compaction of the damaged tissue the bone must be stabilized.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
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.
Claim 2
Independent Claim
133 words
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.
Claim 3
Independent Claim
66 words
A method of treating an vertebral body having a superior endplate and an inferior endplate, comprising the steps of: inserting a container into an vertebral body; deploying said container within said vertebral body; injecting a bone filler material into said container under pressure; whereby said pressure supplies a distraction force to move said superior and inferior endplates apart; ending injection after said endplates have moved apart.
Claim 4
Independent Claim
66 words
A method of treating an vertebral body having a superior endplate and an inferior endplate, comprising the steps of: inserting a container into an vertebral body; deploying said container within said vertebral body; injecting a bone filler material into said container under pressure; whereby said pressure supplies a distraction force to move said superior and inferior endplates apart; ending injection after said endplates have moved apart.
Claim 5
Independent Claim
58 words
A method of treating an vertebral body comprising the steps of: creating a cavity in the vertebral body through an access aperture; inserting a container into said vertebral body; said container having a fill passage coupled to said container; deploying said container within said vertebral body; injecting a bone filler material into said container through said fill passage.
Claim 6
Independent Claim
