Abstract

Instruments and methods are provided for manipulating a bone anchor and a spinal fixation element. The instruments and methods disclosed herein are particularly suited to facilitate rotation of a bone anchor relative to another bone to correct the angular rotation of the vertebrae attached to the bone anchor. The instrument does not require the spinal fixation element to be inserted into the bone anchor prior to manipulation. The instrument further may be used in the insertion of the spinal fixation element into the bone anchor.
