A thermally sterilized bone paste useful in the orthopedic arts, for example in the repair of non-union fractures, periodontal ridge augmentation, craniofacial surgery, implant fixation, impaction grafting, or any other procedure in which generation of new bone is deemed necessary, is provided by a composition comprising a substantially bioabsorbable osteogenic compound in a matrix of 11-19 %, and preferably about 15-19 % (w/w) or thermally sterilized gelatin. In various embodiments, the osteogenic compound is selected from (i) demineralized bone matrix (DBM); (ii) bioactive glass ceramic, BIOGLASS, bioactive ceramic, calcium phosphate ceramic, hydroxyapatite, hydroxyapatite carbonate, corraline hydroxyapatite, calcined bone, tricalcium phosphate, or like material; (iii) bone marrow extracts, vascular proliferation or regeneration growth factors, bone morphogenetic protein, TGF-.beta., PDGF, or mixtures thereof, natural or recombinant; and (iv) mixtures of (i)-(iii). The thermally sterilised gelatine may be a commercially available grade of gelatine which is both thermally and irradiatively sterilized. |
