Abstract
The present invention relates to a device for the stabilization of the spine comprising at least two pedicle screws and at least one interjacent linking member. The present invention further relates to pedicle screws which combine the advantages of a monoaxial screw with those of a polyaxial screw by avoiding the drawbacks of these screw types. This objective is achieved due to the fact that the screw head is supported on the screw shank such that it cannot be moved for providing an optimal reducibility of the vertebrae, wherein a movable ball element is present in the screw head, which facilitates the introduction of the linking member and fixates the same once the introduction has been effected.
