    摘要: An implant is provided as a solid aggregate of bone-derived elements, e.g., particles, powders, granules, fibers, strips and/or large pieces of xenogenic, allogenic, transgenic, tissue engineered or autologous cortical and/or cancellous bone, employing as binding agent for the bone-derived elements a precipitate or crystalline bridge of metal oxide, metal hydroxide, metal salt of an inorganic acid, metal salt of an organic acid, metal-containing silica based glass, or mixture thereof, the binding agent possessing at least slight solubility in polar solvent, adjacent bone-derived elements being bonded to each other through engagement with particles or bridge-like structures of bonding agent.

    摘要: An osteoinductive demineralized bone matrix, corresponding osteoimplants, and methods for making the osteoinductive demineralized bone matrix are disclosed. The osteoinductive demineralized bone matrix may be prepared by providing demineralized bone and altering the collagenous structure of the bone. The osteoinductive demineralized bone matrix may also be prepared by providing demineralized bone and compacting the bone, for example via mechanical compaction, grinding into a particulate, or treatment with a chemical. Additives such as growth factors or bioactive agents may be added to the osteoinductive demineralized bone matrix. The osteoinductive demineralized bone matrix may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, may induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation. The osteoinductive demineralized bone matrix may also be used as a delivery device to administer bioactive agents.

    摘要: A non-destructive method for evaluating the strength of cancellous bone includes the steps of performing at least two of the following tests on each cancellous bone of a population of cancellous bones: a manual compression test, an apparent density test, and an appearance test; determining a compressive strength for each cancellous bone based on the two tests performed; comparing the determined compressive strength of each cancellous bone against a predetermined compressive strength requirement; and, eliminating a subset of cancellous bone from the population of cancellous bone, which subset of cancellous bone fails to meet the predetermined compressive strength requirement.
