1. A method of breaking a reduction tab, comprising:
advancing a distal end of a guide rod into a recess of a bone anchor;
advancing a tab breaker instrument distally over the guide rod to move a distal end of the instrument over first and second reduction tabs extending proximally from a receiver of the bone anchor such that the first reduction tab is received within a first opening of a first shaft of the instrument, such that the second reduction tab is received within a second opening of a second shaft of the instrument, and such that a central longitudinal axis of the instrument is collinear with a central longitudinal axis of the receiver; and
manipulating the first and second shafts to break the first and second reduction tabs off of the receiver.
