摘要： A fixation device for bones includes a member which has at least one bore for receiving a bone screw, wherein the at least one bore comprises a first internal thread portion. The bone screw has a first shaft section provided with a first external thread portion arranged to cooperate with the internal thread portion of the at least one bore, and a head section having a diameter larger than that of the shaft section to provide a catch arranged to engage with a stop formed in the bore. The bone screw further has a second shaft section which includes a clearance groove extending between the catch of the head section and the external thread of the first shaft section. The clearance groove allows disengagement of the two thread portions, such that the bone screw is prevented from being unscrewed off the bore when it is loosened within the adjacent bone.

摘要： A polyaxial bone anchoring device includes an anchoring element having a shaft and a head; a receiving part having a channel for receiving a rod therein, a coaxial bore and a seat portion for receiving the head; a pressure element having a head contacting surface portion; wherein the head is pivotable with respect to the receiving part and can be fixed at an angle by exerting pressure via the pressure element onto the head, and wherein the head has an oversize with respect to the head contacting surface portion such that an interference fit is achieved that clamps the head by the friction between the head and the head contacting surface portion. The curved outer surface portion has a largest diameter and the head contacting surface contacts the head at least in a region including the largest diameter.
