ABSTRACT:
An apparatus, method and system for treating spinal conditions by moving or spatially fixing at least one vertebra relative to another vertebra. The invention includes a link member the ends of which are configured to be secured to adjacent vertebrae and which are offset from a central portion of the link member. The link members can be in the form of a C-shaped or V-shaped rod or plate to form the offset. The offset provides increased bone volume that can be used for grafts or fusion. Attachment structure in the form of bone screws, bolts, or hook members are provided to secure the link members to respective vertebrae. A plurality of link members can be connected in chain-like fashion to connect multiple points on a plurality of vertebrae even though those points are nonlinear. In another aspect of the invention, the links are pre-curved in the lateral plane for use in correcting spinal conditions or deformities.
