Abstract: A procedure for determining a plan for cutting a bone sample for use as an implant provides scanning the bone with a CT scanning system to provide slice images of the bone. The scanning system then determines the cortical or cancellous bone dimensions and density of the bone. Determining such dimensions and density permits accurate planning and preparation of an implant graft that is correlated to the predetermined plan without waste of bone through cutting test specimens to determine the bone parameters. Other images techniques that provide slice images are also disclosed.

Abstract: An osteoimplant composite comprising a plurality of particles of an inorganic material, a bone substitute material, a bone-derived material, or any combination thereof; and a polymer material with which the particles are combined. The composite is either naturally moldable or flowable, or it can be made moldable or settable. After implantation, the composite may be set to provide mechanical strength to the implant. The inventive composite have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength required for most orthopedic applications. The invention also provides methods of using and preparing the moldable and flowable composites.

Abstract: The present invention is an osteoimplant that comprises two or more portions, wherein two or more of the portions are self-interlockable with one another to form the desired osteoimplant. The components of the osteoimplant may be of the same material or of different materials. Suitable materials may include cortical bone, cancellous bone, structural polymer, other biomaterial, or any combination thereof.

Abstract: 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.

Abstract: Biological-based polyurethanes and methods of making the same. The polyurethanes are formed by reacting a biodegradable polyisocyanate (such as lysine diisocyanate) with an optionally hydroxylated biomolecule to form polyurethane. The polymers formed may be combined with ceramic and/or bone particles to form a composite, which may be used as an osteoimplant.

Abstract: Osteoinductive compositions and implants having increased biological activities, and methods for their production, are provided. The biological activities that may be increased include, but are not limited to, bone forming; bone healing; osteoinductive activity, osteogenic activity, chondrogenic activity, wound healing activity, neurogenic activity, contraction-inducing activity, mitosis-inducing activity, differentiation-inducing activity, chemotactic activity, angiogenic or vasculogenic activity, and exocytosis or endocytosis-inducing activity. In one embodiment, a method for producing an osteoinductive composition comprises providing partially demineralized bone, treating the partially demineralized bone to disrupt the collagen structure of the bone, and optionally providing a tissue-derived extract and adding the tissue-derived extract to the partially demineralized bone.

Abstract: Methods of repairing a joint formed by at least two bone sections are provided wherein a biocompatible osteogenic band fabricated from an osteogenic biological material such as bone, tendon, ligament and collagen is affixed to two or more bone sections.

Abstract: A load-bearing osteoimplant which comprises a shaped, coherent aggregate of bone particles.

Abstract: Present inventions present composites of particles and polymers, as well as methods of making such composite and uses thereof. A low or non-porous composite comprises a plurality of bone particles; and polyurethane components with which the bone particles are combined. Provided composites can be prepared in a one-shot process. Alternatively or additionally, composites can be prepared by compression molding under a high pressure. Before or after implantation, provided composites may be set to form a hardened state of composites that provides mechanical strength and supports the in-growth of cells.

Abstract: A cortical bone implant is formed of two or more planks of bone which are connected with one or more offset pins. The pins may be right circular cylinders inserted into a corresponding offset bore which offset bends the inserted pin. The bending creates compression and tensile loads in the pin which loads creates friction compression forces on the planks connecting them to the pins by friction. The pins may have different shapes to form offset configurations in place of the offset bores for friction attachment to the planks. The implants may be formed of flat or L-shaped planks or bones formed into other shapes including interlocking arrangements. Processes and fixtures are disclosed for forming the pins, planks and implants. Various embodiments of the pins, planks, implants and processes are disclosed.
