The present invention broadly comprises an assembly for performing a gradual lateral spinal alignment of a spine. The assembly includes a toggle bolt that includes a shaft and a toggle wing, a rigid stabilizing rod with an orifice, a cable attached to the toggle bolt and a tube enclosing the cable and extending out of the patient's back. The toggle bolt extends through the stabilizing rod and is positioned against the misaligned spine. The toggle bolt is placed in a bore through the body of a vertebra and deployed. The attached cable is pulled using the stabilizing rod as a brace to pull the spine into alignment. The device allows the spine to be gradually placed into alignment helping to avoid trauma on the spine and surrounding tissue.
