摘要: The present invention encompasses the finding that certain treatments (e.g., surface modifications) to particulate materials can provide surprising and unexpected benefits and/or features to composites and/or compositions as described herein. In some embodiments, such benefits and/or features may render particular composites and/or compositions particularly useful in a certain therapeutic context (e.g, for repair of tibial plateau, femoral head, craniofacial, or lateral mandibular body defects). The present invention demonstrates that certain composites and/or compositions wherein the particular material is or comprises defatted bone have surprising and beneficial attributes.

摘要: Present inventions present composites of bone particles and polyurethane(s), as well as methods of making such composite and uses thereof. A porous composite comprises a plurality of bone particles; and polyurethanes with which the bone particles are combined. To prepare a porous composite, a composition comprise a plurality of bone particles, polyurethane precursors including polyisocyanate prepolymers and polyols, water and catalyst. A composition is either naturally moldable and/or injectable, or it can be made moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength and supports the in-growth of cells. Inventive composites have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength for most orthopedic applications.

摘要: Embodiments of the present inventions comprise composites of bone particles and polyurethane(s), as well as methods of making such composite and uses thereof. Certain embodiments further comprise a growth factor that can be provided in powder form. Growth factors may be bone morphogenic proteins, such as rhBMP-2. A porous composite comprises a plurality of bone particles, polyurethanes with which the bone particles are combined, and at least one growth factor. A composition may be moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength and supports the in-growth of cells. Inventive composites have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength for most orthopedic applications.

摘要: Present inventions present composites of particles and polymers, as well as methods of making such composite and uses thereof. A low or non-porous composite comprises a plurality of bone particles; and polyurethane components with which the bone particles are combined. Provided composites can be prepared in a one-shot process. Alternatively or additionally, composites can be prepared by compression molding under a high pressure. Before or after implantation, provided composites may be set to form a hardened state of composites that provides mechanical strength and supports the in-growth of cells.
