SPINAL ROD-TO-ROD CONNECTORS

Abstract: a polyaxial rod connector comprising a body having an external surface. the connector body is intersected by an imaginary first reference plane and an imaginary second reference plane perpendicular to the first plane. the first body portion is on one side of the first plane and defines a first spinal rod passage defining a first passage axis and a first set screw opening defining a first axis perpendicular to the first passage axis. a second body portion is adjoined to the first body portion, defining a second spiral rod passage defining a plurality of passage axes, and a second set screw opening defining a second axis perpendicular to the plurality of second passage axes. the first passage axis is non-parallel with one of second passage axes in the second plane. either the first or second spinal rod passage have an hourglass shaped cross-section parallel to the second plane.
