Abstract

A transverse connector for coupling between first and second elongate members of a spinal stabilization system. The transverse connector includes a connector arm, a first coupling assembly proximate a first end of the arm, and a second coupling assembly proximate a second end of the arm. The first and second coupling assemblies are secured to the connector arm through a plurality of mating engagement features, such as dovetail grooves.
