A dynamic stabilizing device ( 1 ) for bones ( 3 ), in particular for vertebrae, includes two bone anchoring elements ( 2 ) spaced from one another, which are connectable via fastening elements ( 4 ) with at least one rod ( 5 ) that is at least partly elastic. The rod ( 5 ) has an adjustable device ( 7 ) for affecting its elasticity, which is adjustable before and/or after the implantation of the stabilizing device ( 1 ). The adjustable device ( 7 ) is formed, such that it changes the free length of an elastic section ( 11 ) of the rod ( 5 ). The adjustable device ( 7 ) includes a carriage that is displaceable over the rod ( 5 ), and the carriage ( 20 ) engages the rod ( 5 ) on a peripheral side at least partially. |
