  • Patent number: 10617526
    Abstract: Embodiments of the present technology include a method of making a bone composite graft for administration to a patient. The method may include combining a human cadaveric bone material with a plurality of polymethyl methacrylate binder particles and spincasting the combined human cadaveric bone material and polymethyl methacrylate binder particles to produce the bone composite graft. The method may also include ablating the bone composite graft to increase the surface area of bone material exposed. The human cadaveric bone material may be immobilized in the plurality of polymethyl methacrylate binder particles. The human cadaveric bone material may be present in an amount that is 50 weight percent of the bone composite graft, or less. Additionally, the bone composite graft may have a yield strength that is at least 13,000 N/cm2 and no greater than 15,000 N/cm2.

  • Publication number: 20170367826
    Abstract: Embodiments of the present technology include a graft for administration at a treatment site of a patient. The graft may include a human cadaveric bone material bonded together with a polymeric binder. The human cadaveric bone material may include demineralized bone particles. The demineralized bone particles may have an average diameter less than 1.1 mm, less than 750 ?m, less than 500 ?m, or less than 250 ?m. The human cadaveric bone material may include non-demineralized bone, cancellous bone, and/or cortical bone in embodiments. In some embodiments, bone from animals other than humans may be used, and the patient may be an animal other than a human.
