title: Demineralized bone matrix and native bone morphogenetic protein in orthopaedic surgery.
abstract: The recognition that demineralized bone matrix could induce bone formation when placed in mammalian skeletal muscle led to preclinical studies of crude native insoluble bone morphogenetic protein and noncollagenous protein, followed by the clinical application of demineralized bone matrix, chemosterilized autolyzed antigen-extracted allogenic bone, and autolyzed antigen-extracted allogenic bone matrix gelatin. Cultural norms and regulatory agencies influence the availability of different demineralized bone matrix preparations in different parts of the world, but there is continued interest in the biologic structure of native insoluble bone morphogenetic protein and noncollagenous protein aggregates and the applied science of osteoinduction and osteoconduction in reconstructive orthopaedic surgery. Demineralized bone matrix is not widely available in Asia, but tissue processing facilities in the United States distribute demineralized bone matrix materials with different carriers, handling properties, and possibly osteoinductive potential. The purpose of the current study was to review the development and use of various preparations of demineralized bone matrix materials.
