Systems for vertebral adjustments and rod reduction

A system for one or more surgical procedures, comprising:

• a first arm including a first aperture for coupling with a first screw extender that attaches to a first vertebra;
• a second arm pivotably coupled to the first arm and including a second aperture having a first configuration and a second configuration;
• a removable sleeve for the second aperture in the first configuration for coupling with a second screw extender that attaches to a second vertebra;
• a reducer for the second aperture in the second configuration to reduce a surgical rod within the second screw extender;
• and
• a coupler that positions the first arm relative to the second arm for compression and distraction of the first vertebra relative to the second vertebra in the first and second configurations,
• wherein the first aperture includes a first diameter and the second aperture includes a second diameter greater than the first diameter, the second diameter configured to receive one of the removable sleeve and the reducer.
