Abstract
A flexible, nonstress-bearing bone prosthesis is disclosed that comprises demineralized bone powder contained within a medical grade porous flexible casing made from polymeric fibers or a micro-porous membrane. The pores of the casing are smaller than the particle size of the bone powder but large enough to permit ingress of body cells associated with bone formation.
Claims6
An implantable nonstress-bearing bone prosthesis comprising particulate demineralized bone, dentin, or mixtures thereof contained within the interior of a medical grade flexible porous closed container made of bioerodible collagen, the pores of which are smaller than the particle size of the particulate demineralized bone or dentin, but large enough to permit passage of osteogenic and/or mesenchymal cells.
