Abstract
A spinal stabilization system for installation to the posterior of the spinal column that includes a pair of anchoring members affixed to adjacent vertebrae and which may have screw threads to carry out that affixation. The anchoring members each have external head ends for the attachment of a flexible shaft that thus spans between the vertebrae and allows motion between those adjacent vertebrae. The flexible shaft is made of a monolithic body having no moving components that could generate debris and fail mechanically. Exemplary flexible shafts suitable for use in this system includes one having at least one slot that may be a spiral slot, a shaft having pairs of oppositely disposed slots formed in the body with adjacent pairs angularly displaced apart or a flexible shaft having a serpentine slot formed therein. The flexible shaft is controlled to have a desired flexibility.
