Abstract: The present invention is directed to a dynamic fixation system for engaging, via bone fixation elements, one or more parts of a patient's body. Preferably, the dynamic fixation system is used to engage one or more vertebrae for stabilizing the attached vertebrae with respect to one another while still permitting the vertebrae to move with respect to one another. The dynamic fixation system may include a first rod having first and second ends, a second rod having first and second ends, and a damping component and/or a damping mechanism for interconnecting the first and second rods. In one embodiment, the damping component is injection molded in-between the one of the ends of the first rod and one of the ends of the second rod so that the first and second rods are prevented from separating with respect to one another but are still permitted to move with respect to one another.
