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 method for assembling a bone anchoring device includes inserting a bone anchoring element in a first holder of a tool and inserting a receiving part in a second holder of the tool, actuating the tool from a first configuration towards a second configuration to insert a head of the bone anchoring element into the receiving part; continuing actuation of the tool towards the second configuration to move a locking ring and a receiving part body of the receiving part relative to each other until the locking ring assumes a second position with respect to the receiving part body in which the locking ring is latched to the receiving part body in a position where the locking ring compresses a portion of the receiving part body to compress the head, such that the head is held in and cannot be removed from the receiving part body and the bone anchoring element is held adjustably at a first angular position relative to the receiving part, and removing the attached bone anchoring element and receiving part from the tool. The tool is configured for the execution of the steps according to the method.

摘要： A spacer for insertion between two vertebrae includes a variable axial length and comprises a first member having a hollow interior and a tubular wall and a second member having a hollow interior and a tubular wall the second member being slidable within the first member in an axial direction for adjusting an overall length. At least the first member or the second member comprises an access opening in its wall, the opening having a size which is adapted for inserting bone grafts through the opening into the interior. The spacer further comprises a length adjustment structure being engageable with an expansion tool for telescoping the second member relative to the first member and a locking structure for fixing the axial length. The access opening, the length adjustment structure and the locking structure are arranged so as to be accessible from the same side of the spacer. The spacer allows in situ filling of bone grafts into its interior and an improved handling.
