Abstract
A crosslink member for securing spinal rods is disclosed having connector ends that include a brace and a locking member, each having an arcuate face resting on and securing a spinal rod. The locking member is secured by a cam member that rotates relative to the locking member and that cams against the connector to displace the cam member. The crosslink includes a male connector with a cylindrical cross rod received by a cavity in a female connector. The cross rod is secured by a pivotable clamp device in the female connector, and the cross rod connector and female connector may pivot, rotate, and telescope relative to each other. To reduce size without sacrificing pivot sweep, the cross rod has beveled edges, and the cavity of the female connector has windows to provide pivot clearance.
