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 method for implanting a rod implant along a spine of a patient back, the method comprising: a) minimally invasively passing the rod implant distally through a first minimally invasive incision in the patient back by causing a first end of the rod implant to distally displace along a first central longitudinal channel of a first elongated guide tool minimally invasively extending through the first minimally invasive incision from a first connection of a distal region of the first elongated guide tool to a head of a first bone anchor at a proximal region of the first bone anchor, the first bone anchor implanted in a first vertebra of the spine, and the head comprising a first rod-receiving channel;b) after the first end has minimally invasively passed through the first minimally invasive incision as recited in step a), exiting the first end from the first central longitudinal channel via a first longitudinally extending side slot of the first elongated guide tool and displacing the first end towards a second elongated guide tool along a trajectory diagonal to a longitudinal axis of the first elongated guide tool, the second elongated guide tool minimally invasively extending through a second minimally invasive incision from a second connection of a distal region of the second elongated guide tool to a head of a second bone anchor at a proximal region of the second bone anchor, the second bone anchor implanted in a second vertebra of the spine, and the head of the second bone anchor comprising a second rod-receiving channel;c) entering the first end into a second central longitudinal channel of the second elongated guide tool via a second longitudinally extending side slot of the second elongated guide tool; andd) causing the rod implant near the first end to enter the second rod-receiving channel and the implant rod near a second end of the rod implant opposite the first end to enter the first rod-receiving channel. 2. The method of claim 1, wherein, in achieving the steps recited in step d), the first end projects through a third longitudinally extending side slot of the second elongated guide tool opposite the second side slot. 3. The method of claim 2, wherein, further in achieving the steps recited in step d), the second end projects through a fourth longitudinally extending side slot of the first elongated guide tool opposite the first side slot. 4. The method of claim 3, wherein the first and fourth longitudinally extending side slots comprise different lengths. 5. The method of claim 4, wherein the first longitudinally extending side slot is longer than the fourth longitudinally extending side slot. 6. The method of claim 2, wherein the second and third longitudinally extending side slots comprise different lengths. 7. The method of claim 6, wherein the second longitudinally extending side slot is longer than the third longitudinally extending side slot. 8. The method of claim 1, wherein the first connection is a result of spaced-apart opposed legs of the distal region of the first elongated guide tool splaying apart as the head of the first bone anchor is forced proximally between the spaced-apart opposed legs, a feature of at least one of the legs snapping into engagement with a groove defined in a radially outward cylindrical surface of the head of the first bone anchor. 9. The method of claim 8, further comprising application of a force directed to proximally displace the spaced-apart opposed legs relative to the head of the first bone anchor once the feature is received in the groove. 10. The method of claim 9, wherein the groove comprises a planar boundary perpendicular to a longitudinal center axis of the head of the first bone anchor and perpendicularly intersecting the radially outward cylindrical surface of the head of the first bone anchor, the planar boundary making complementary planar surface contact with the feature when the feature is received in the groove. 11. The method of claim 8, further comprising application of a force directed to proximally displace the spaced-apart opposed legs relative to the head of the first bone anchor, thereby setting the feature in the groove in a manner that inhibits splaying apart of the spaced-apart opposed legs. 12. The method of claim 11, wherein the groove comprises a recessed overhanging configuration at a proximal boundary of the groove, and the feature comprises a proximally pointing free extent that is received by the recessed overhanging configuration. 13. The method of claim 1, further comprising delivering a threaded closure top into the first rod-receiving channel via a route extending along the first central longitudinal channel, and threading the threaded closure top into the first rod-receiving channel to secure the rod implant within the first rod-receiving channel. 14. The method of claim 1, further comprising rotating the first elongated guide tool relative to the head of the first bone anchor to disconnect the first elongated guide tool from the head of the first bone anchor. 15. The method of claim 1, wherein the first and fourth side slots are aligned with the first rod-receiving channel when the rod implant enters the first rod-receiving channel. 16. The method of claim 1, wherein a width of the first side slot along a length of the first side slot is narrower than another width of the first side slot near a distal end of the first side slot. 17. The method of claim 1, wherein, in achieving the steps recited in step d), an elongated member distally displaces along the first central longitudinal channel of the first elongated guide tool to distally drive the rod implant from the first central longitudinal channel into the second rod-receiving channel. 18. The method of claim 1, wherein step b) further comprises causing the first end to pass through a fifth longitudinally extending side slot of a third elongated guide tool and a sixth longitudinally extending side slot of the third elongated guide tool as the first end is displaced towards the second elongated guide tool from the first longitudinally extending side slot of the first elongated guide tool, the fifth and sixth longitudinally extending side slots opposite each other and the third elongated guide tool minimally invasively extending through a third minimally invasive incision from a third connection of a distal region of the third elongated guide tool to a head of a third bone anchor at a proximal region of the third bone anchor, the third bone anchor implanted in a third vertebra of the spine, and the head of the third bone anchor comprising a third rod-receiving channel. 19. The method of claim 18, wherein step d) further comprises causing the rod implant intermediate the first and second ends to enter the third rod-receiving channel. 20. The method of claim 18, wherein the fifth and sixth longitudinally extending side slots comprise different lengths. 21. The method of claim 1, wherein at least one of the first or second bone anchor comprises a bone screw. 22. The method of claim 21, wherein the bone screw is at least one of polyaxial or cannulated.
