A dynamic fixation medical implant having at least two bone anchors includes a longitudinal connecting member assembly having an elongate core that includes the following integral features: a stop plate; a slitted segment; and a threaded segment or a second stop plate. The assembly may further includes a spacer and a nut. The spacer surrounds the slitted segment and the nut is rotatingly mated with the threaded segment. The nut abuts and compresses the spacer against the stop plate and places distractive tension on the slitted segment. Alternative embodiments include a molded spacer cooperating with a neutral, tensioned or bent slitted segment and in some embodiments cooperating with a cable or elastic band.
