Methods and devices for minimally invasive spinal fixation element placement
First Claim
1. A minimally invasive method for delivering a spinal fixation rod to a spinal anchor site, comprising:
- percutaneously delivering a spinal screw to a vertebra with a percutaneous access device mated to the spinal screw, the percutaneous access device including a lumen extending therethrough and defining a longitudinal axis;
manipulating a spinal fixation rod extending lengthwise through the lumen in the percutaneous access device in a first orientation substantially parallel to the longitudinal axis of the percutaneous access device to extend in a second orientation angled with respect to the first orientation to position the spinal fixation rod in relation to the spinal screw.

Abstract
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.

24. A minimally invasive surgical method, comprising:
-
making a first percutaneous incision in a patient; creating a first pathway from the first percutaneous incision to a single anchor site on a first vertebra; placing a first spinal screw through the first percutaneous incision, the first spinal screw having a percutaneous access device mated thereto; advancing the first spinal screw with the percutaneous access device mated thereto along the first pathway to the single anchor site; and placing a fixation rod lengthwise through the first pathway in an orientation substantially parallel to a longitudinal axis of the first pathway. - View Dependent Claims (25, 26, 27)
