Methods and apparatus for treating bones, including, in one or more embodiments, methods and apparatus for treatment of vertebral fractures that include a containment assembly for cement containment and/or a balloon assembly for maintaining vertebral height. Methods for treating a bone comprising: creating a cavity in the bone; inserting a containment jacket into the cavity; inserting a balloon into the containment jacket; inflating the balloon; and introducing a filler material into the containment jacket with isolation of the balloon from the filler material.

1. A method for treating a bone comprising: creating a cavity in the bone, wherein the cavity has a proximal end and a distal end;inserting a containment jacket into the cavity through the proximal end of the cavity;inserting a balloon into the containment jacket, wherein the balloon has a proximal end closer to the proximal end of the cavity and a distal end closer to the distal end of the cavity, wherein an enclosure is disposed over the balloon, the enclosure having a proximal end closer to the proximal end of the balloon and a distal end closer to the distal end of the balloon, wherein the distal end of the balloon extends past the distal end of the enclosure;inflating the balloon, wherein the enclosure remains generally unstressed and completely intact when the balloon is in a fully inflated working state; andintroducing a filler material into the containment jacket while the balloon remains inflated within the containment jacket, wherein the filler material is introduced into a space in the containment jacket that is more distal than a distal most end of the balloon; andpermanently positioning the containment jacket in the bone,wherein the containment jacket allows for interdigitation of the filler material with cancellous bone. 2. The method of claim 1 wherein threads hold the enclosure in place over the balloon. 3. The method of claim 1 wherein the enclosure comprises a nose that is bonded to a nipple of the balloon. 4. The method of claim 1 wherein the containment jacket comprises a dividing wall, the dividing wall separating the containment jacket into a first section and a second section. 5. The method of claim 4 wherein the dividing wall includes an opening for providing access to the second section from the first section. 6. The method of claim 5 comprising threading the balloon through the opening over a guide wire. 7. The method of claim 4 wherein the filler material is inserted into the second section, and wherein the balloon is inflated in the first section. 8. The method of claim 1 further comprising: deflating the balloon;removing the balloon from the containment jacket; andintroducing an additional volume of the filler material into the containment jacket after removal of the balloon. 9. The method of claim 8 wherein the containment jacket is attached to a tubular member, and the method further comprises detaching the containment jacket from the tubular member. 10. The method of claim 9 comprising: providing a cutting mechanism having a distal end and that comprises an outer tube, cutting tips at the distal end of the cutting mechanism, and a plunger for forcing the cutting tips outward;introducing the cutting mechanism into the tubular member;moving the plunger down the outer tube to force the cutting tips outward and into engagement with the containment jacket; androtating the cutting mechanism to cut the containment jacket and detach the containment jacket from the tubular member. 11. The method of claim 9 comprising: providing a cutting mechanism having a distal end and that comprises a main body with an inner cavity that includes an opening at the distal end of the cutting mechanism, an elongated member disposed in the inner cavity, and a cutting tip disposed on the elongated member;introducing the cutting mechanism into the tubular member;moving the elongated member down the cavity of the outer tube to extend the cutting tip from the opening at the distal end of the cutting mechanism and into contact with the containment jacket; androtating the cutting mechanism to cut the containment jacket and detach the containment jacket from the tubular member. 12. The method of claim 1, wherein the cavity is created in a vertebral body, and wherein the balloon is inflated in the cavity to maintain the height of the vertebral body. 13. The method of claim 1, wherein the cavity is created in a vertebral body, and wherein the balloon is inflated in the cavity to increase the height of the vertebral body. 14. The method of claim 1, wherein the filler material is introduced into the containment jacket through an inner lumen of the balloon. 15. The method of claim 14, wherein the inner lumen extends through the entire length of the balloon. 16. The method of claim 1, wherein the balloon occupies less than half the volume of the containment jacket. 17. The method of claim 1, wherein the filler material passes through the balloon and into the containment jacket, such that the filler material accumulates on an outer face of the balloon and not within the balloon. 18. A method for treating a bone comprising: creating a cavity in the bone, wherein the cavity has a proximal end and a distal end;inserting a containment jacket into the cavity through the proximal end of the cavity;inserting a balloon into the containment jacket, wherein the balloon has a proximal end closer to the proximal end of the cavity and a nipple at a distal end closer to the distal end of the cavity, wherein an enclosure is disposed over the balloon, the enclosure having a proximal end closer to the proximal end of the balloon and a nose at a distal end closer to the distal end of the balloon, wherein the nipple of the balloon extends beyond the nose of the enclosure;inflating the balloon, wherein the enclosure remains generally unstressed and completely intact when the balloon is in a fully inflated working state; andintroducing a filler material into the containment jacket while the balloon remains inflated within the containment jacket, wherein the filler material is introduced into a space in the containment jacket that is more distal than a distal most end of the balloon; andpermanently positioning the containment jacket in the bone,wherein the containment jacket allows for interdigitation of the filler material with cancellous bone.
