Abstract

A spinal rod connector assembly for use with a vertebral bone screw has an articulating clamp for 1) fixing an orientation of the spinal rod connector assembly relative to and on the vertebral bone screw, and 2) attaching a separate spinal rod onto the spinal rod connector assembly in concert with one another. The articulating clamp resides in a body of the spinal rod connector assembly and transfers a received downward force laterally to a spinal rod component of the spinal rod connector assembly which is configured to abut the spinal rod and hold the spinal rod between itself and a spinal rod holder of the spinal rod connector assembly. The articulating clamp thus improves the force transfer efficacy of the system.
