摘要：

In a bone screw (1) with an open receptacle for a connection element, in particular a connection rod, the risk of jamming is reduced by avoiding beveled flights at the lead-in of the thread pair, at least on the thread halves (2) of the receptacle or the attachment element (4, 6, 7, 9) which can be placed onto the head of the screw.
