Abstract: Embodiments of the present inventions comprise composites of polyurethane(s), osteoconductive matrix, and, optionally, a growth factor. Embodiments further comprise methods of making such composite and uses thereof. The osteoconductive matrix can be a tricalcium phosphate, bioglass, or the like, and can include particles that are surface modified. Growth factors can be provided in powder form, including bone morphogenic proteins such as rhBMP-2. 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.

Abstract: 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.

Abstract: Embodiments of the presently-disclosed subject matter provide composites that comprise a tissue graft and a biofilm dispersal agent. The tissue graft can be bone tissue graft, a soft tissue graft, or the like. In specific embodiments the tissue graft is a polyurethane graft and in other embodiments the tissue graft is bone particles, such as demineralized bone matrix. The biofilm dispersal agent can be one or more D-amino acids. The presently-disclosed subject matter further includes methods for treating tissue of a subject that comprise administering the present composites as well as methods for manufacturing the present composites.
