1. A cross-connector system for use during a spinal fixation procedure comprising:
at least one coupling device defining a coupling bore and having a pair of downwardly extending arms adapted to be coupled to a rod or a bone engaging member;
a contoured bar having a first end offset from a second end, the first end defining a bore having a central axis and the second end defining a slot;
an expansion ring received within the bore of the contoured bar, the expansion ring including a slot configured to expand the expansion ring in a circumferential direction;
a locking device received through the expansion ring and the coupling bore for coupling the at least one coupling device to the contoured bar, the locking device operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar is fixed relative to the central axis of the bore so as to fixedly couple the contoured bar to the at least one coupling device; and
a planar bar having a first end and a second end, the first end of the planar bar coupled to the slot to enable relative movement between the contoured bar and the planar bar.
