An improved flexible component used for dynamic stabilization of spinal segments for the treatment of vertebrae deformities and injuries and for the replacement of a complete or segment of the body of a vertebra in the spine is described. The flexible component is comprised of a suitable implant material with a longitudinal bore the entire length and an appropriately formed slots that extend spirally around the flexible spinal element either continuously or segmentally. The flexible component can be encapsulated, fully or partially, in a suitable implant grade elastomeric resilient material. When used for a dynamic stabilization device, the element is attached to the vertebral bodies by pedicle screws know to those in the art.
