A reducer for seating a spinal rod in two bone anchors in a spinal fixation procedure, the reducer comprising:

• a) a connector comprising a connector body having a guide cavity, the guide cavity configured for securely but releasably receiving a guide assembly from a distal end of the connector thereby connecting the reducer to the guide assembly;
• b) a reduction shaft comprising an upper shaft with exterior threading, a lower shaft coupled to the upper shaft, and a pair of reduction legs at or near a distal end of the lower shaft;
• c) a central shaft positioned at least partly within a hollow bore of the reduction shaft, the central shaft comprising a rotational grip fixedly attached at or near a proximal end thereof;
• and
• d) a reduction grip positioned proximal to the connector, wherein the exterior threading of the upper shaft mates with an interior threading of the reduction grip.
