    摘要: Compositions for use in treating and repairing orthopedic defects are provided. The compositions are especially useful for performing percutaneous vertebroplasty, percutaneous kyphoplasty and other procedures. When cured, the compositions are relatively solid but compressible, and prior to curing are viscous liquids with a low enough viscosity to fill voids in cavities such as voids within fractured vertebrae. Optionally, the properties of a composition according to the invention can be adjusted taking into account the hardness and density of the orthopedic structure to be repaired. Also disclosed are devices and methods for using the compositions, and a kit containing components for forming and utilizing the composition.

    摘要: By providing an elastic form stable material which is capable of being delivered directly to a specific desired location within a living creature and provides increased strength and rigidity to the injected location, disorders of the trabecular bone or subchondral tissue of a living creature are able to be effectively treated. Treatment of necrosis of the bone beneath the cartilage in skeletal joints and other defects in bony or cartilaginous structures is achieved with a variation of the subject material specific to each application. In the preferred method, the elastic form stable material is injected directly into the affected area, thereby achieving the desired result.
