Spinal stabilization devices coupled by torsional member

Spine stabilization devices, systems and methods are provided in which torsion member extends between first and second stabilization devices that are oppositely positioned relative to the vertebrae. The torsion member includes a (i) a first segment that is substantially co-planar with and perpendicular to the axis of at least one of the stabilization devices; (ii) a second segment that extends from the first segment and that is angularly and upwardly oriented relative to the first segment; (iii) a third segment that extends from the second segment, is substantially perpendicular to at least one of the stabilization devices, and is oriented in a plane that is elevated with respect to, but substantially parallel to, the plane of at least one of the stabilization devices, (iv) a fourth segment that extends from the third segment and that is a substantial mirror image of the second segment; and (v) a fifth segment that extends from the fourth segment and that is a substantial mirror image of the first segment.. Methods for mounting the torsion member with respect to attachment members associated with opposed pedicle screws are also disclosed.
