  • Publication number: 20160250025
    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.

  • Publication number: 20160243284
    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.

  • Publication number: 20160231056
    Abstract: Methods for treating bulk bone tissue are provided. The methods comprise contacting bulk bone tissue or frozen bulk bone tissue with an effective amount of a supercritical fluid so as to dry the bulk bone tissue. In various embodiments, the supercritical fluid destroys contaminants such that the frozen bulk bone tissue is 99.9% substantially pure. In various embodiments, contaminants removed from the frozen bulk bone tissue include lipids, viruses, bacteria, pyrogens, prions, micro-organisms and/or pathogens. In some embodiments, the supercritical fluid causes a 3 log reduction of bacteria within the frozen bulk bone tissue.

  • Patent number: 8672980
    Abstract: There is provided an implant retaining device, which has the effect of preventing an intervertebral implant from jutting out of the receiving bed. The implant retaining device generally includes a plate having at least one throughbore to receive a screw, and a screw for securing the plate to the vertebrae. The plate may be dimensioned to cover a portion of the opening of a receiving bed, and thus, need only be secured to a single vertebral body. In an alternate embodiment, the plate may be used during bone fracture correction procedures to prevent a bone screw from backing out of engagement with adjacent bone sections. A method of retaining an intervertebral implant using the device is also provided.

  • Patent number: 8562648
    Abstract: An implant unit used in surgery has a body made from osteogenic implantable material and including an implant portion and a retaining portion, which is coupled to and extends transversely to the implant portion. The retaining portion is attached to the sidewall of the adjoining vertebral body or mammal bone to prevent displacement of the implant portion relative to the vertebral body or mammal bone and to accelerate fusion therebetween.
