Abstract

The invention concerns a posterior dynamic spinal stabilisation device (10) which can be used to stabilise a spinal section, typically in the lumbar region. The device includes pedicle screws (12) which can be screwed into holes reamed in respective spinal vertebrae. A flexible cable (14) connects the protruding heads (26) of the screws to one another with a spacing structure (16) between the screw heads. The spacing structure is used to set the distance between the screw heads and is of adjustable, preferably telescopically adjustable, length.
