    • 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.
    • 本发明提供了可围绕脊柱的一部分定位的动态稳定装置。 稳定装置通常可以包括第一部件和第二部件,其中第一和第二部件彼此可移动地联接以限定弓形运动路径。 稳定装置还可以包括可定位在第一和第二调节开口内的一个或多个调节元件,以影响第一和第二部件之间的运动路径和/或运动的行为和特征。 此外,一个或多个电阻元件可以可调节地定位在第一和第二调节开口内和/或两者中,以提供当第一和第二部件相对于彼此移动时所经受的力的电阻和/或阻尼。 稳定装置还可以限定具有三个自由度以适应脊柱的运动的关节。
