    摘要: The use of autogenous bone graft is the current gold standard in the 1.5 million bone-grafting surgeries performed annually in the United States. Although this practice has resulted in high rates of fusion success, it is associated with increased operative time and blood loss, along with a significant degree of donor-site morbidity. Additionally, in certain settings such as revision cases, multilevel constructs, or in patients with medical comorbidities, autogenous bone graft may exist in limited quantity and quality. This significant need for a suitable alternative to autogenous bone graft has stimulated great interest in the exploration of bone graft substitutes and extenders.

    摘要: In one embodiment, the method comprises providing tissue, preparing the tissue, and treating the tissue to improve remodeling characteristics of the tissue. The tissue may be, for example, cortical bone. Treating the tissue to improve remodeling characteristics may comprise heating the tissue, treating the tissue with a chemical, or other. Heating the tissue may be done in the absence of oxygen and may comprise heating the tissue in a vacuum, heating the tissue in an inert atmosphere, heating the tissue in a reducing atmosphere, coating the tissue with a protective coating and heating the tissue, or other. Further embodiments comprise treating the tissue in supercritical fluids, for example, to dry or virally inactivate the tissue.

    摘要: The present invention provides methods of improving the osteogenic and/or chondrogenic activity of a bone matrix, e.g., a dermineralized bone matrix (DBM), by exposing the bone matrix to one or more treatments or conditions. In preferred embodiments the bone matrix is derived from human bone. The treatment or condition may alter the structure of the bone matrix and/or cleave one or more specific proteins. Cleavage may generate peptides or protein fragments that have osteoinductive, osteogenic, or chondrogenic activity. Preferred treatments include collagenase and various other proteases. The invention further provides improved bone and cartilage matrix compositions that have been prepared according to the inventive methods and methods of treatment using the compositions. The invention further provides methods of preparing, testing, and using the improved bone matrix compositions. On a assay comprises exposing relatively undifferentiated mesenchymal cells to a bone matrix composition and measuring expression of a marker characteristic of osteoblast or chondrocyte lineage(s). Increased expression of the marker relative to the level of the marker in cells that have been exposed to a control matrix (e.g., an inactivated or untreated matrix) indicates that the treatment or condition increased the osteogenic and/or chondrogenic activity of the bone matrix. Suitable cells include C2C12 cells. A suitable marker is alkaline phosphatase. The inventive methods increase the osteogenic and/or chondrogenic activity of human DBM when tested using this assay system.

    摘要: An osteoinductive composition, corresponding osteoimplants, and methods for making the osteoinductive composition are disclosed. The osteoinductive composition comprises osteoinductive factors, such as may be extracted from demineralized bone, and a carrier. The osteoinductive composition is prepared by providing demineralized bone, extracting osteoinductive factors from the demineralized bone, and adding the extracted osteoinductive factors to a carrier. Further additives such as bioactive agents may be added to the osteoinductive composition. The carrier and osteoinductive factors may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, can induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation. Also, in some embodiments, the osteoinductive composition can be used as a delivery device to administer bioactive agents.
