摘要
A bone screw includes a screw head and a seating sleeve or tulip on the screw head. The bone screw includes two sleeve flanks having a thread. A seat for a rod for surgical connection of adjacent bone screws is formed between the sleeve flanks. On at least one of the sleeve flanks, a guide surface extending in the circumferential direction for a clamping screw to be screwed into the thread is configured on the run-in side, with the guide surface offset in the radial direction vis-à-vis the thread diameter of the female thread.
