A surgical fixation system includes at least one anchoring element with an anchoring portion for anchoring to a bone and with a receiving portion for a stabilization element for connecting to a further anchoring element. The stabilization element is arrangeable and fixable in the receiving portion with a fixing element. The fixation system includes an abutment element arranged on the receiving portion. The receiving portion abuts against the anchoring portion for the placement of the stabilization element. The abutment element has at least one deformation region for deforming in dependence on a fixing force of the fixing element acting on the stabilization element.

A medical cross connector, a corresponding matching torque wrench, and a corresponding medical product set that includes the medical cross connector in combination with at least one bone implant and/or other matching surgical accessory. The medical cross connector includes a cross strut for connecting two longitudinal rods that can be brought into operative engagement for orientation of vertebrae of a spinal column, and at least one clamping head mounted pivotably on the cross strut in an angular bearing. The clamping head has a rod receptacle and a clamping screw. A clamping tooth applies a clamping force to one of the longitudinal rods when the rod is inserted into the rod receptacle. The clamping tooth is mounted pivotably about a pivot axis via a floating bearing. The floating bearing permits a pivoting movement and a lateral movement of the pivot axis of the clamping tooth.

The present invention relates to a connection element for a spine stabilization system which comprises a first end for fixing to a first bone fixation device, a second end for fixing to a second bone fixation device and an intermediate portion arranged or formed between the two ends and defining a longitudinal axis. At least one of the two ends takes the form of a coupling element for fixing the connection element to a bone fixation device in at least one defined orientation relative to the longitudinal axis. The coupling element has a shape other than a circular cylinder.

The present invention relates to a connection element for a spine stabilization system comprises a first end for fixing to a first bone fixation device, a second end for fixing to a second bone fixation device and an intermediate portion arranged or formed between the two ends and defining a longitudinal axis. At least one of the two ends takes the form of a coupling element for fixing the connection element to a bone fixation device in at least one defined orientation relative to the longitudinal axis. The coupling element has a shape other than a circular cylinder.

A surgical device is used for temporarily stiffening an at least partially flexible intermediate section of a connecting element for a spinal column stabilization system. The connecting element includes a first attachment section for fixing to a first bone fixation device and a second attachment section for fixing to a second bone fixation device. The at least partially flexible intermediate section is arranged between the first and second attachment sections. The intermediate section defines at least one recess configured to enable deformation of the intermediate section. The surgical device includes at least one blocking element which is adapted to be brought into engagement with the intermediate section at least partially with a positively locking connection for temporarily preventing deformation of the flexible intermediate section. An improved spinal column stabilization system includes at least one first bone fixation device, at least one second bone fixation device and a connecting element.
