35. A dynamic spine stabilization system comprising: a first anchor adapted to be anchored to a pedicle of a first vertebra, and a second anchor adapted to be anchored to an opposite pedicle of the first vertebra; a third anchor adapted to be anchored to a pedicle of a second vertebra, and a fourth anchor adapted to be anchored to an opposite pedicle of the second vertebra; a first horizontal rod connecting between the first anchor and the second anchor; a second horizontal rod connecting between the third anchor and the fourth anchor; a deflection rod having a first deflectable end and a second deflectable end; a connector which attaches a middle portion of the deflection rod to a middle portion of the first horizontal rod; a first vertical rod connected at one end by a first pivotable joint to the first deflectable end of the deflection rod and at another end to the second horizontal rod; and a second vertical rod connected at one end by a second pivotable joint to the second deflectable end of the deflection rod and at another end to the second horizontal rod.
