A method for attaching a fixation system to the spine of a patient, the fixation system including at least two bone anchors and a spinal rod linking the at least two bone anchors, comprising the steps of: connecting a first bone anchor to a first retractor blade, the first retractor blade having a first length, advancing the first bone anchor and first retractor blade together to a first spinal vertebra, and anchoring the first bone anchor through a pedicle of the first spinal vertebra;connecting a second bone anchor to a second retractor blade, the second retractor blade having a second length different than the first length, advancing the second bone anchor and second retractor blade together to a second spinal vertebra, and anchoring the second bone anchor through a pedicle of the second vertebra, wherein the second vertebra is separated from the first vertebra by an intervertebral disc space and the first vertebra, second vertebra, and intervertebral disc space comprise a first spinal level;connecting a retractor body to the first retractor blade and the second retractor blade and operating the retractor body to expand an operative corridor formed between the first retractor blade and second retractor blade from the skin level of the patient to the spine;adjusting the angle of the operative corridor; andlinking the first bone anchor and the second bone anchor with the spinal rod. 89. The method of claim 88, adjusting the angle of the operative corridor is accomplished by moving a proximal end of the first retractor blade and a proximal end of the second retractor blade in the same direction while a distal end of the first retractor blade remains positioned adjacent the first pedicle and a distal end of the second retractor blade remains positioned adjacent the second pedicle. 90. The method of claim 88, comprising the additional step of advancing a third retractor blade towards the spine, connecting the third retractor blade to the retractor body, and operating the retractor body to further expand the size of the operative corridor. 91. The method of claim 88, wherein anchoring the first bone anchor to the first spinal bone comprises advancing a first anchor portion into said first spinal bone and subsequently attaching a first receiver portion to the first anchor portion and anchoring the second bone anchor to the second spinal bone comprises anchoring a second anchor portion to the second spinal bone and subsequently attaching a second receiver portion to the second anchor portion.
