1. A minimally invasive surgical method comprising:
- making a first incision in a patient;
expanding the first incision to create a first pathway from the first incision to a first vertebra and a second vertebra;
advancing a first anchor through the pathway to a first anchor site on the first vertebra;
advancing a second anchor through the pathway to a second anchor site on the second vertebra;
making a percutaneous incision in the patent;
advancing a third anchor through the percutaneous incision to a third anchor site on the third vertebra;
positioning a first end of a fixation element in the first pathway;
advancing the first end of the fixation element subcutaneously to the third anchor; and
coupling the fixation element to the first anchor, the second anchor, and the third anchor.

Abstract
A minimally invasive surgical method may include positioning a first anchor and second anchor in a first vertebra and a second vertebra, respectively, through a first incision made on a first side of a patient'"'"'s spine, percutaneously positioning a third anchor in a third vertebra through a second incision distinct from the first incision, advancing the first end of a fixation element from the first incision subcutaneously to the third anchor, and coupling the fixation element to the first anchor, the second anchor, and the third anchor.
