Abstract

The pedicle screw comprises a head section (1) which is formed for the acceptance of a longitudinal support (4) and a shaft section (3) which is formed to be anchored in the bone. The shaft section (3) provides a double-threaded threading (4) which has an angle of inclination <beta> in the range of 5 DEG and 16 DEG.
