1. A method of reducing multiple levels of a spinal column in a surgical procedure to correct a spinal deformity, the method comprising:
implanting a first bone anchor to a first vertebra, the first bone anchor including a first housing having a first opening to receive a rod;
implanting a second bone anchor to a second vertebra, the second bone anchor including a second housing having a second opening to receive the rod;
implanting a third bone anchor to a third vertebra, the third bone anchor including a third housing having a third opening to receive the rod;
positioning the rod in the first opening;
securing the rod to the first housing;
positioning the rod proximate the second opening and the third opening;
coupling a first rotating rod reducer to the second housing, the first rotating rod reducer comprising: first and second reducing elements that are configured to slide relative to each other; and a first pair of handles configured to slide the first and second reducing elements relative to each other when actuated; wherein the first pair of handles are configured to rotate about an axis of the first and second reducing elements;
reducing the rod into the second housing using the first rotating rod reducer;
rotating the first pair of handles into a transverse plane of the spinal column;
reducing the rod into the third housing using an additional rod reducer; and
securing the rod to the second and third housings.
