A vertebral column implant for the elastic stabilization of motion segments ( 1, 2 ) comprising an elastically bendable connecting element ( 5 ) which can be passed through the seats ( 4 ) of a number of pedicle screws ( 3 ) having offset seat axes ( 6 a , 6 b , 6 c) and be anchored. The connecting element is bendable elastically about every axis of its cross-section in such a way that the connecting element can be passed through, or inserted in, the seats of the screwheads, one behind the other, even when the seats are not situated on one and the same axis. The connecting element and the seat in the screwhead each have wholly, or in part, a structured surface, in such a way that the structured surface of the seat engages the structured surface of the connecting element, and shifting can be prevented in assembled condition.
