A method of repairing a bone joint by using a simple and flexible artificial ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis to return stability to the spine subsequent to a surgical spine procedure, is disclosed. The method includes anchoring the artificial ligament to at least two vertebrae to aid in restoring stability to the compromised joint. The artificial ligament is also disclosed.

The invention claimed is: 1. A method of repairing a joint formed by at least two bone sections, said method comprising: positioning a body fabricated from a generally flexible material that permits a degree of flexibility approximating a natural ligament, said body having a first end with at least one aperture extending therethrough and a second end with at least one aperture extending therethrough, across said joint such that said first and second ends are, respectively, aligned with one of said at least two bone sections; and anchoring said first and second ends, respectively, to one of said at least two bone sections to facilitate flexible movement between said at least two bone sections, wherein said body facilitates movement between said body and at least one of the two bone sections. 2. The method of claim 1, wherein said at least two bone sections are vertebrae. 3. The method according to claim 1, further comprising: anchoring an intermediate portion of said body to an intermediate bone section located between said at least two bone sections to which said first and second ends are anchored. 4. The method of claim 3, further comprising: forming at least one anchoring bore on said body at said intermediate portion to facilitate anchoring said body to said intermediate bone section. 5. The method of claim 1, wherein said body is anchored to said at least two bone sections in a manner allowing controlled relative movement between said body and said at least two bone sections. 6. The method of claim 1, wherein anchoring is achieved with elements selected from the group consisting of expandable bolts, screws, non-threaded fasteners, and bone screws. 7. A method of repairing a portion of a vertebral column, said method comprising: positioning a body fabricated from a generally flexible material, that permits a degree of flexibility approximating a natural ligament, said body having a first end with at least one aperture extending therethrough, a second end with at least one aperture extending therethrough, and an intermediate portion having a width substantially less than corresponding widths of said first and second ends, across a joint such that said first and second ends are, respectively, aligned with a first and a second bone section, wherein said first and second bone sections are on opposite sides of said joint; and anchoring said first and second ends of said body, respectively, to said first and second bone sections to facilitate flexible movement between said first and second bone sections, wherein said body facilitates movement between said body and at least one of said bone sections. 8. The method of claim 7, further comprising: determining at least one intermediate anchoring position between said first and second bone sections; forming at least one intermediate anchoring bore on said body at a position corresponding to said at least one intermediate anchoring position; and anchoring said body to a structure at said at least one intermediate anchoring position. 9. The method of claim 8, wherein anchoring is achieved with elements selected from the group consisting of expandable bolts, screws, non-threaded fasteners, and bone screws. 10. The method of claim 7, wherein anchoring is achieved with elements selected from the group consisting of expandable bolts, screws, non-threaded fasteners, and bone screws. 11. The method of claim 7, wherein said bone sections are vertebrae. 12. The method of claim 7, wherein said at least one aperture is slotted. 13. The method of claim 7, wherein the method provides a body that replaces part or all of the supporting function of a ligament previously resected at the joint. 14. The method of claim 7, wherein the method accompanies a procedure selected from the group consisting of bone graft, bone fusion, implant, artificial disc, anterior spinal ligament, ligament replacement, intervertebral prosthesis, and ligament repair. 15. The method of claim 12, wherein the at least one aperture is slotted in the longitudinal direction with respect to a long axis of the body. 16. The method of claim 1, wherein said at least one aperture is slotted. 17. The method of claim 1, wherein the method provides a body that replaces part or all of the supporting function of a ligament previously resected at the joint. 18. The method of claim 1, wherein the method accompanies a procedure selected from the group consisting of bone graft, bone fusion, implant, artificial disc, anterior spinal ligament, ligament replacement, intervertebral prosthesis, and ligament repair. 19. The method of claim 16, wherein the at least one aperture is slotted in the longitudinal direction with respect to a long axis of the body. 20. A method of repairing a joint formed by at least two bone sections, said method comprising: positioning a body fabricated from a generally flexible material that permits a degree of flexibility approximating a natural ligament, said body having a first end with at least one aperture extending therethrough and a second end with at least one aperture extending therethrough, across said joint such that said first and second ends are, respectively, aligned with one of said at least two bone sections, wherein the at least one aperture at the first end or second end provides translational movement of the body with respect to one of said at least two bone sections; and anchoring said first and second ends, respectively, to one of said at least two bone sections to facilitate flexible movement between said at least two bone sections, wherein said body facilitates movement between said body and at least one of the two bone sections.
