A method and system for reducing and affixing two separated bone segments, the system having a bone plate with a pair of positioning slots, and a pair of elongated manipulating members with anchoring structures, the anchoring structures sized to pass through the positioning slots and for advancement into the bone segments. The bone plate is loosely mounted to the bone segments across the separation gap and a manipulating member is screwed into each bone segment through a positioning slot. The manipulating members are then used to reposition the bone segments by moving them together longitudinally within the slots. Fixation bone screws are inserted into the bone segments through screw receiving apertures to securely affix the bone plate to the repositioned bone segments. The manipulating members are then removed.
