1. A polyaxial rod connector, the polyaxial rod connector comprising a connector body, the connector body having an external surface, the connector body being intersected by an imaginary first reference plane and an imaginary second reference plane perpendicular to the imaginary first reference plane,
a. a first body portion being on a first side of the imaginary first reference plane, the first body portion defining openings to a first spinal rod passage defining a first spinal rod passage axis and a first internally threaded set screw opening defining a first set screw axis, the first internally threaded set screw opening positioned on the first body portion to intersect the first spinal rod passage;
b. a second body portion adjoined to the first body portion on a second side of the imaginary first reference plane, the second body portion defining openings to a second spinal rod passage defining a plurality of second spinal rod passage axes, and a second internally threaded set screw opening defining a second set screw axis, the second internally threaded set screw opening positioned on the second body portion to intersect the second spinal rod passage;
c. wherein the first spinal rod passage axis is non-parallel with at least one of the plurality of second spinal rod passage axes in the imaginary second reference plane; and
d. wherein one of the first spinal rod passage and the second spinal rod passage comprises a generally hourglass shaped cross section parallel to the imaginary second reference plane.
