1. A surgical method for en bloc derotating a spinal column, the method comprising:
coupling a first clamp to a first screw extension coupled to a first vertebra;
coupling a second clamp to a second screw extension coupled to a second vertebra;
rotating the first and second clamps relative to one another to derotate the first vertebra and the second vertebra relative to one another; and
coupling a linkage directly to the first and second clamps and locking the linkage to maintain the first and second clamps in a fixed position relative to one another, thereby maintaining the first vertebra and the second vertebra in a derotated position relative to one another.
