    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: 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.
