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.

Claims

1. A method for repairing a joint formed by at least two adjacent vertebrae, the method comprising:

providing a biocompatible osteogenic band comprising bone having a first end and a second end, the osteogenic band comprising a plurality of braided or woven elongated sections of bone, and

affixing said first end of the biocompatible osteogenic band to a first vertebra and affixing said second end to a second vertebra, the first and second vertebrae being identical to, or encompassing, the adjacent vertebrae, to maintain the joint formed by the adjacent vertebrae under tension.

2. The method of claim 1 wherein the osteogenic band comprises cortical bone.

3. The method of claim 1 wherein the osteogenic band comprises bone selected from the group consisting of autogeneic bone, allogeneic bone and xenogeneic bone.

4. The method of claim 1 wherein the elongated sections of bone are demineralized.

5. The method of claim 1 wherein the elongated sections of bone are segmentally demineralized.

6. The method of claim 1 wherein the plurality of elongated sections of bone is demineralized.

7. The method of claim 6 wherein the plurality of elongated sections of bone is segmentally demineralized.

8. The method of claim 6 wherein the plurality of elongated sections of demineralized bone is chemically cross linked.

9. The method of claim 1 wherein the biocompatible osteogenic band further comprises one or more substances selected from the group consisting of an antiviral agent, antimicrobial agent, antibiotic agent, biocidal/biostatic sugar, amino acid, peptide, vitamin, inorganic element, protein synthesis cofactor, hormone, endocrine tissue, synthesizer, enzyme, polymer-cell scaffold with parenchymal cells, angiogenic drug, collagen lattice, antigenic agent, cytoskeletal agent, cartilage fragment, chondrocytes, bone marrow cells, mesenchymal stem cells, natural extract, genetically engineered living cells, tissue transplant, demineralized bone powder, DNA, bioadhesive, bone morphogenic protein, osteoinductive factor, fibronectin, transforming growth factor-beta, endothelial cell growth factor, cementum attachment extracts, ketaserin, insulin-like growth factor, platelet derived growth factor, epidermal growth factor, interleukin, human alphathrombin, fibroblast growth factor, periodontal ligament chemotactic factor, growth hormone, bone digester, antitumor agent, immuno-suppressant, permeation enhancer and nucleic acid.

10. The method of claim 1 wherein the biocompatible osteogenic band is affixed to the posterior side of a spine.

11. The method of claim 10 wherein the site of affixation of the osteogenic biocompatible band to the two or more vertebrae of the spine is selected from the group consisting of vertebral body, pedicle, transverse process, mamillary process, inferior articular process, superior articular process, spinous process and accessory process.

12. The method of claim 1 wherein the biocompatible osteogenic band has a dimension between about 1 cm and about 1 meter in length, between 2 mm and about 30 mm in thickness, and between about 2 mm and about 30 mm in width.
