Methods for push distraction and for provision of therapy to adjacent motion segments

A method to selectively provide distraction to two different adjacent motion segments comprising:

• providing a selected spinal therapy to a first motion segment through use of a first assembly engaged with at least a first vertebral body;
• engaging a second assembly with a second vertebral body immediately caudal to the first vertebral body;
• pushing a proximal end of the first assembly with a rotating portion of the second assembly to push the first assembly axially away from the second vertebral body without rotating the first assembly;
• engaging a third assembly with a third vertebral body caudal to the second vertebral body;
• and
• pushing a proximal end of the second assembly with a rotating portion of the third assembly to push the second assembly axially away from the third vertebral body without rotating the second assembly.
