Implants and methods for minimally invasive bone treatment, including repositioning of vertebrae, may comprise insertion of a bobbin having a wire, string, thread or band, coiled around the bobbin. During coiling, the diameter of the bobbing/band complex may increase to push against the inner side of the endplates of the vertebral body, and augment the vertebral body. The implant may also take the form of a coiled sleeve which when inserted into the vertebral body is uncoiled and pushes against the inner side of the endplates of the vertebral body, restoring height of the vertebral body. The implant may also take the form of fibrous masses comprised of a thread or other relatively thin structure. The fibrous mass may be coiled, woven, matted, tangled or otherwise formed into a wool-like mass or body having a desired configuration. Expansion of the expandable member may reposition fractured bone to a desired height. |
