1. A method to implant in a patient a dynamic spine stabilization, motion preservation system comprising the steps of: accessing the surgical site; implanting first and second anchor systems in a first vertebra; implanting third and fourth anchor systems in a second vertebra; positioning a first horizontal anchor system relative to the first and second anchor systems with a vertical rod system connected to the first horizontal anchor system; positioning a second horizontal anchor system relative to the third and fourth anchor systems; deploying vertical rods from a vertical rod system from a position about parallel to the first horizontal rod system to a position about perpendicular to the first horizontal rod system; and moving the vertical rods into engagement with mounts on the second horizontal anchor system.
10. The method of claim 1 including moving a saddle head of the anchor system about a spherical connection with a bone anchor until the desired position of the saddle head is reached with respect to the horizontal rod system and locking the saddle head against the horizontal rod system and locking the saddle head and the horizontal rod system against a spherical connector about which the saddle head moves about a bone anchor head.
