Abstract

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.
