摘要:

A pedicle screw (1) for use in the monosegmental or multisegmental stabilization of the spinal column comprises a thread and a receiver portion. In order to facilitate the mounting and to reduce the stress of the screw and the threaded rods for connection therewith, a threaded shaft part (2) and a receiver part (3) are mutually connected in an articulated manner.
