  • Patent number: 8858600
    Abstract: The present invention provides a dynamic stabilization device positionable about a portion of a spinal column. The stabilization device may generally include a first component and a second component, where the first and second components are movably coupled to one another to define an arcuate path of motion. The stabilization device may also include one or more adjustment elements positionable within first and second adjustment openings to affect the path of motion between the first and second components and/or the behavior and characteristics of the movement. In addition, one or more resistive elements may be adjustably positionable within either and/or both of the first and second adjustment openings to provide resistance and/or dampening of the forces experienced as the first and second components move relative to one another. The stabilization device may further define a joint having three degrees of freedom to adapt to movement of a spinal column.

  • Publication number: 20090222011
    Abstract: A targeting surgical instrument for use in spinal disc replacement includes a first arm, a second arm and a body portion. The first arm is configured to be longitudinally aligned with a mid-line of a spine and to be at least partially received on an endplate of a lower vertebra of spinal cavity. The spinal cavity is defined by a lower vertebra and an upper vertebra of the spinal cavity. The second arm is positioned at an angle relative to the first arm. The second arm defines an insertion angle for a spinal implant. The body portion connects the first arm and the second arm. The body portion includes a plurality of radial opaque markers located to allow alignment of the first arm on the mid-line of the spine.
