摘要： Implants and methods for bone treatment, preferably minimally invasive 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. Such increase in diameter can push against the inner side of the endplates of the vertebral body, and augment the vertebral body to its original height. The implant may also take the form of a coiled sleeve which when inserted into the vertebral body is uncoiled. The force of the uncoiling sleeve pushes against the inner side o the endplates of the vertebral body, restoring the vertebral body to its original height. The implant may also take the form of fibrous masses comprised of a thread or other relatively thin structure, for example a fiber or strand, of any biocompatible material having desired characteristics, for example a shape memory alloy, titanium, stainless steel, another metal or metal alloy, a ceramic, a composite or any combination thereof. The, strand, thread or other fiber 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 within the vertebral body or other bone may reposition the fractured bone to a desired height and augment the bone to maintain the desired height. A bone cement or other filler can be added to further treat and stabilize the vertebral body or other bone.
