1. A spinal fixation system, comprising: a first bone anchor having a bone engaging portion and a spinal fixation element receiving portion with opposed arms extending substantially parallel to a longitudinal axis that extends from a proximal end to a distal end of the bone anchor and configured to receive a spinal fixation element therebetween; a cross connector rod having first and second ends; and a connecting assembly including a clamp and a laterally offset cross connector receiving portion configured to receive one of the first and second cross connector ends such that when a portion of the cross connector rod is disposed therein, the cross connector rod is offset from the longitudinal axis of the bone anchor, wherein the connecting assembly is configured to fix a location of the cross connector rod with respect to the spinal fixation element receiving portion.
