Disclosed are methods and apparatus for the provision of spinal therapy to three or more adjacent motion segments accessed through a trans-sacral approach. The spinal therapies include fusion and dynamic stabilization with and without a distraction of the most cephalad motion segment of the two or more adjacent motion segments provided therapy. The disclosure includes methods and apparatus to impart a distraction on a second more caudal motion segment after providing therapy to the more cephalad motion segment.
