    Abstract: The present invention provides a pedicle screw system, which may include a bone fixation element having an elongate body. The elongate body may include a threaded segment having one or more spiral-oriented grooves, a neck segment adjacent to the threaded segment, and a head segment which is able to receive and/or couple to an orthopedic instrument or implant. The pedicle screw system may further include an anchoring element movably positionable about the bone fixation element. The anchoring element may include one or more elongate teeth which may be slidably positionable into a desired tissue region.

    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.
