During the screwing-in procedure, the thickened part widens the clamping sleeve, such that the latter is pressed with its jacket against the wall of the receiving seat. In this way, pressing at a stable angle is achieved in any desired orientation of the bone screw.WO 2012/072735 1/6 PCT/EP2O11/071504 I 46 46 46 4S4 12 g IA5 Fig I I 54 Fig. 2V
