Claims32
An osteoimplant which comprises a coherent aggregate of elongate bone particles selected from the group consisting of substantially fully demineralized elongate bone particles, partially demineralized elongate bone particles, superficially demineralized elongate bone particles, and mixtures thereof, wherein mutually contacting elongate bone particles are mechanically entangled with each other, the coherent aggregate of elongate bone particles being shaped in a mold to predetermined dimensions in the substantial absence of pressure or mechanical shaping forming an open pore, sponge-like structure, wherein the open pore, sponge-like structure enables the osteoimplant to absorb fluids while generally retaining the predetermined shape.
