Polyaxial pedicle screw having provisional fastening means

Abstract

A polyaxial pedicle screw includes a screwed shaft section for anchoring the pedicle screw in a vertebra, on one axial end of which a shaft head is configured which is coupled in a rotating and/or pivoting manner as well as in a tensile-force transmitting manner to a receiving sleeve for a longitudinal support. The receiving sleeve has a fastening means for selective positional fastening of the receiving sleeve with respect to the shaft section, the fastening means at least consisting of an inlay/pin mounted in the receiving sleeve and acting on the shaft head, and a locking element acting on the inlay/pin. The inlay/pin is configured with attachment points or engagement elements, which are not covered or overlapped by the locking element, for the provisional introduction of a compressive force on the inlay/pin parallel to the locking element.
