Abstract
A dynamic vertebral stabilization device for constraining motion of adjacent vertebrae is provided. The bone stabilization device comprises a first plate having a vertebral mating surface for positioning against a vertebrae, wherein the first plate defines a recess. The device further comprises a second plate having a vertebral mating surface for positioning against an adjacent vertebrae. The second plate includes a projection configured to travel in the recess of the first plate. The vertebral mating surface of the first plate is non-coplanar with respect to the vertebral mating surface of the second plate.
Claims24
A dynamic vertebral stabilization device for constraining motion of adjacent vertebrae, said stabilization device comprising:
- a first plate having a vertebral mating surface for positioning against a vertebrae, said first plate defining a recess;
- and
- a second plate having a vertebral mating surface for positioning against an adjacent vertebrae, said second plate including a projection configured to travel in said recess of said first plate,
- wherein said vertebral mating surface of said first plate is non-coplanar with respect to said vertebral mating surface of said second plate.
A dynamic vertebral stabilization device for constraining motion of adjacent vertebrae, said stabilization device comprising:
- a first plate configured to be fixedly coupled to a vertebrae, said first plate defining a thru-hole;
- and
- a second plate configured to be fixedly coupled to an adjacent vertebrae, said second plate including a projection configured to travel in said thru-hole of said first plate.
A method of installing a dynamic vertebral stabilization device comprising a superior plate and an inferior plate onto adjacent vertebrae comprising the steps of:
- coupling the superior plate to the inferior plate;
- mounting the superior plate to a lumbar vertebrae;
- and
- mounting the inferior plate to a sacral vertebrae.
