Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patient's spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.

1. A minimally invasive method for delivering a spinal fixation rod to one or more spinal screw sites, comprising: percutaneously delivering a first spinal screw though a first incision, the first spinal screw having a first percutaneous access device mated thereto, the first percutaneous access device including a lumen extending therethrough and defining a longitudinal axis;advancing a second spinal screw through a second incision that is separate and distinct from the first incision, the second spinal screw having a second percutaneous access device mated thereto, the second percutaneous access device including a lumen extending therethrough and defining a longitudinal axis;introducing a leading end of a spinal fixation rod through a slot formed in a sidewall of the first percutaneous access device; andmanipulating the spinal fixation rod to position the spinal fixation rod to extend between the first and second spinal screws. 2. The method of claim 1, wherein the spinal fixation rod is manipulated with the leading end positioned subcutaneously. 3. The method of claim 1, further comprising percutaneously delivering a third spinal screw though a third incision that is separate and distinct from the first and second incisions, the third spinal screw having a third percutaneous access device mated thereto, the third percutaneous access device including a lumen extending therethrough and defining a longitudinal axis, and wherein the spinal fixation rod is manipulated to extend between the first, second, and third spinal screws. 4. The method of claim 1, wherein introducing the spinal fixation rod comprises manipulating a manipulator device coupled to the spinal fixation rod to introduce the spinal fixation rod into the first percutaneous access device, and wherein manipulating the spinal fixation rod comprises manipulating the manipulator device to position the spinal fixation rod to extend between the first and second spinal screws. 5. The method of claim 1, further comprising delivering first and second locking mechanisms through the first and second percutaneous access devices and applying the first and second locking mechanisms to the first and second spinal screws to fixedly couple the spinal fixation rod to the first and second spinal screws. 6. A minimally invasive method for delivering a spinal fixation rod to one or more spinal screw sites comprising: percutaneously delivering a first spinal screw though a first incision, the first spinal screw having a first percutaneous access device mated thereto, the first percutaneous access device including a lumen extending therethrough and defining a longitudinal axis;advancing a second spinal screw through a second incision that is separate and distinct from the first incision, the second spinal screw having a second percutaneous access device mated thereto, the second percutaneous access device including a lumen extending therethrough and defining a longitudinal axis;passing a spinal fixation rod through opposed sidewall openings in the first percutaneous access device; andmanipulating the spinal fixation rod to position the spinal fixation rod to extend between the first and second spinal screws. 7. A minimally invasive method for delivering a spinal fixation element to one or more spinal screw sites, comprising: forming first and second separate and distinct minimally invasive percutaneous skin incisions;delivering a first spinal screw with a first percutaneous access device mated thereto through the first skin incision to a first vertebra such that the first percutaneous access device mated to the first spinal screw extends from the first spinal screw up through the first skin incision;delivering a spinal screw with a second percutaneous access device mated thereto through the second skin incision to a second vertebra such that the second percutaneous access device mated to the second spinal screw extends from the second spinal screw up through the second skin incision;passing a leading end of a spinal fixation element through opposed sidewall openings formed in one of the first and second percutaneous access devices to position the leading end subcutaneously and to position the spinal fixation element to extend between the first and second spinal screws. 8. The method of claim 7, further comprising: forming a third minimally invasive percutaneous skin incision that is separate and distinct from the first and second skin incisions; anddelivering a spinal screw with a third percutaneous access device mated thereto through the third skin incision to a third vertebra such that the third percutaneous access device mated to the second spinal screw extends from the third spinal screw up through the third skin incision;wherein the spinal fixation element is positioned to extend between the first, second, and third spinal screws. 9. The method of claim 7, wherein the first and second spinal screws are delivered over a guidewire extending from the skin incision to the vertebra. 10. A minimally invasive method for delivering a spinal fixation rod to one or more spinal screw sites, comprising: transitioning a spinal fixation rod from a first orientation to a second orientation, wherein during transitioning a leading end of the spinal fixation rod is passed through a sidewall opening formed in a first percutaneous access device and the leading end of the spinal fixation rod is subcutaneously positioned, the first percutaneous access device being mated to a first spinal screw implanted in a first vertebra; andpositioning the leading end of the spinal fixation rod in a second spinal screw implanted in a second vertebra and positioning a trailing end of the spinal fixation rod in the first spinal screw, the second spinal screw having a percutaneous access device mated thereto. 11. The method of claim 10, wherein during transitioning the leading end of the spinal fixation element is moved beneath skin toward the second spinal screw. 12. The method of claim 10, further comprising, prior to transitioning, delivering the first spinal screw with the first percutaneous access device mated thereto through the first skin incision to implant the first spinal screw in the first vertebra, and delivering the second spinal screw with the second percutaneous access device mated thereto through the second skin incision to implant the second spinal screw in the second vertebra. 13. A minimally invasive method for delivering a spinal fixation rod to one or more spinal screw sites, comprising: forming first, second, and third separate and distinct skin incisions above first, second, and third adjacent vertebrae;delivering a first spinal screw with a first percutaneous access device mated thereto through the first skin incision to implant the first spinal screw in the first vertebra;delivering a second spinal screw with a second percutaneous access device mated thereto through the second skin incision to implant the second spinal screw in the second vertebra;delivering a third spinal screw with a third percutaneous access device mated thereto through the third skin incision to implant the third spinal screw in the third vertebra; andpositioning a spinal fixation rod to pass a leading end of the spinal fixation rod through a slot in a sidewall of the second percutaneous access device and to position the leading end in relation to the third spinal screw such that the spinal fixation rod extends between the first, second, and third spinal screws.
