One technique of the present application includes: evaluating a patient having a previously implanted spinal construct and corresponding spinal fusion from an earlier procedure and determining a spinal segment adjacent to the spinal fusion is degenerating after completion of the earlier procedure. After this determination, the previously implanted spinal construct is augmented by attaching a flexible polymer elongated member to the spinal segment adjacent to the spinal fusion with a bone fastener and by coupling the flexible polymer elongated member to one or more elements of the previously implanted spinal construct. In one form, the elongated member is at least partially comprised of polyetheretherketone.
