The disclosure generally relates to rod-coupling assemblies for coupling rods from separate pedicle screw systems. The rod-coupling assemblies generally include at least one rod-receiving body and at least one cam mechanism. The rod-receiving body and cam mechanism cooperate to capture and retain a distraction rod therewith. The cam mechanism includes a helical cam surface that mates with the rod and urges the rod into a retained position by rotation of the cam mechanism. In one embodiment, the assembly is configured to capture and retain two rods with one rod-receiving body. In another embodiment, the assembly is configured to capture and retain a rod and a head portion of a pedicle screw in one rod-receiving body. In yet another embodiment, the assembly includes a lever that is actuated to fix a first rod-receiving body to a second rod-receiving body.
