  • Publication number: 20020120338
    Abstract: Selectively partially and demineralized bone-derived implants, their methods of preparation and use are provided. In one embodiment, a cranial void filler preferably having a T-shape formed of an upper mineralized cortical bone section and at least a partially demineralized lower section adapted to fill a cranial void is disclosed. In another embodiment, a plate preferably having a dog-bone-shape having mineralized and at least partially demineralized sections is disclosed. In a further embodiment, a unitary cord having a first mineralized section with a plurality of slits to provide flexibility and a second at least partially demineralized section is described. Also disclosed is an implant for laminoplasty having at least a partially demineralized section and a mineralized section. A method of forming an implant of demineralized fibers also is disclosed.

  • Publication number: 20020120346
    Abstract: Selectively demineralized bone-derived implants are provided. In one embodiment, a bone sheet for implantation includes a demineralized field surrounding mineralized regions. In another embodiment, a bone defect filler includes a demineralized cancellous bone section in a first geometry. The first geometry is compressible and dryable to a second geometry smaller than the first geometry, and the second geometry is expandable and rehydratable to a third geometry larger than the second geometry.

  • Publication number: 20020120335
    Abstract: Implants for maintaining a distance between cut spinal bones are disclosed. The implants are made of metal, polymer or bone allograft having ends configured to conform to the cut bone ends. The implants have hollow regions for packing osteogenic material. The implant ends have surface projections to reduce slippage. Implants made of bone allograft also have spine contacting ends made of demineralized bone to speed fusion of spine and implant; they may also have bone flaps to fix the implant to the spine. Methods of using the implants are also disclosed.

  • Publication number: 20010056302
    Abstract: The present invention relates to skeletal reconstruction cages and a method of providing variable fit for a skeletal reconstruction cage. The skeletal reconstruction cages include a central body having first and second ends, a first end cap coupled to one end of the central body, and a second end cap coupled to the other end of the central body. At least two of the central body, first end cap, and second end cap are formed from bone. Each of the central body, first end cap, and second end cap may be provided in different sizes so that cages with varying overall heights, and related angulations, may be created.

  • Publication number: 20010039457
    Abstract: The present invention relates to plugs for filling vacancies in bone tissue. The plugs include a body and at least one end cap that are coupled together and may be formed from bone. The body of the plug may be a sleeve, and the plug may further include an insert configured and dimensioned to be received in the sleeve.
