The invention relates to an intervertebral stabilisation system for at least three vertebra, comprising pedicle screws (67) that can be fixed to the vertebra, at least one bar (11) for connecting at least two pedicle screws to a rigid reinforcement system and at least one band (33), which can be pre-tensioned and which, when the stabilisation system is implanted, is surrounded by at least one compressible compression body (77) that is located between two neighbouring pedicle screws, said band connecting the pedicle screws to an elastic support system. According to the invention, a common pedicle screw is assigned both to the reinforcement system and to the support system and the band can be or is connected to the bar by means of a fixing element.
