Abstract
A connection element (1) for stabilizing vertebral bodies that has a variable stiffness along its longitudinal axis in that particularly the cross-section of the connecting element varies along its longitudinal axis and extends over a plurality of bone screws (6). In spite of the varying cross-section (h1, h2), in a preferred embodiment, the same bone screws (6) may be used in all locations by inserting clamping elements (9, 10) of different lengths.
