A method for performing a surgical procedure on the spine of a patient comprises the steps of connecting a first bone anchor to a first retractor blade, 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, 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. The second vertebra is separated from the first vertebra by an intervertebral disc space and the first vertebra, second vertebra, and intervertebral disc space comprises a first spinal level. The method further comprises 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 and second retractor blades from the skin level of the patient to the spine; 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 operating corridor; operating on the first spinal level through the operating corridor; and linking the first bone anchor and the second bone anchor with a spinal rod after operating on the first spinal level. |
