US 8932334 B2
1. In subcombination, an intervertebral bridge linkage device for flexibly fixating a first vertebra of a patient's spine to a second vertebra of the patient's spine, the linkage configured for posterior implantation and used in combination with a first connector mechanism and a first pedicle screw for interconnecting the linkage to the first vertebra, and a second connector mechanism and a second pedicle screw for interconnecting the linkage to the second vertebra, the linkage device comprising:
a rod portion configured for posterior interconnection to the patient's spine when implanted, the rod portion including a first end having a first transversely-oriented cross-sectional area and having a substantially circular cross-sectional area shape, a second end having a second transversely-oriented cross-section area, and a single section disposed between said first end and said second end, said single section having a smaller transversely-oriented cross-sectional area than either said first transversely-oriented cross-sectional area or said second transversely-oriented cross-sectional area;
wherein said single section expands and rotates forward up to 10 degrees when the patient bends their spine in flexion, and
wherein the smaller transversely-oriented cross-sectional area of said single section has a crescent cross-sectional area shape.
2. The subcombination as claimed in claim 1, wherein said rod portion comprises a metal alloy.
3. In subcombination, an intervertebral bridge linkage device for flexibly fixating a first vertebra of a patient's spine to a second vertebra of the patient's spine, the linkage configured for posterior implantation and used in combination with a first connector mechanism and a first pedicle screw for interconnecting the linkage to the first vertebra, and a second connector mechanism and a second pedicle screw for interconnecting the linkage to the second vertebra, the linkage device comprising:
wherein said single section expands and rotates forward up to 5 degrees when the patient bends their spine in flexion, and
4. The subcombination as claimed in claim 3, wherein said rod portion comprises a metal alloy.
This application is a continuation application of U.S. patent application Ser. No. 10/406,895 filed on Apr. 4, 2003, now U.S. Pat. No. 6,966,910, which claimed the benefit of U.S. Provisional Patent Application No. 60/370,708 filed Apr. 5, 2002 entitled “Dynamic Fusion System” which is incorporated herein by reference in its entirety.
