Abstract
A pedicle screw system includes a receiving sleeve for a longitudinal support, a bone screw and a shank head element. The bone screw has a bone thread configured as an outer thread and a connection thread configured as an inner thread. The shank head element has at the proximal end a head on which the receiving sleeve is mounted and, at the distal end, a connection thread configured as an outer thread screwed into the connection thread of the bone screw. The connection threads are configured as multi-threads, each with a distal connection thread portion and a proximal connection thread portion. The distal connection thread portion and the proximal connection thread portion have an identical thread pitch. The distal connection thread portion has a smaller diameter than the proximal connection thread portion.
