Usable elastic element (20) in a stabilization device (100) for bones or vertebrae, which is designed as an essentially cylindrical body with a first end (22) and a second end (22 ) opposite the first and with an elastic section between the first end and the second end, the elastic section by at least two helical springs (26, 27) arranged coaxially thereby being formed that the turns (3) of a helical spring (26) at least in a spring section extend between the windings (4) of another coil spring (27), including the resilient section two recesses (24, 25) formed in the cylindrical body constituting the at least two helical springs (26, 27), it is provided with to a first cylindrical projection (23) first end with an external thread intended to join with a stem (62) or a head (63) of a bone screw (61), to attach a rod section (51) or torque to attach it to a plate (92), and being provided adjacent the second end (22 ) a cylindrical second projection (23), characterized in that the second cylindrical projection is provided with an external thread for attachment to a rod (62) or a head (63) of a bone screw (61), to a rod section (51 ) or to attach it to a plate (92), and because there is no provision bore coaxial to the central axis M of the element elastic (20).Elemento elástico (20) utilizable en un dispositivo de estabilización (100) para huesos o vértebras, que está configurado como un cuerpo esencialmente cilíndrico con un primer extremo (22) y un segundo extremo (22) opuesto al primero y con una sección elástica entre el primer extremo y el segundo extremo, estando formada la sección elástica por al menos dos resortes helicoidales (26, 27) dispuestos coaxialmente de tal modo que las espiras (3) de un resorte helicoidal (26) al menos en una sección del resorte se extienden entre las espiras (4) de otro resorte helicoidal (27), incluyendo la sección elástica dos escotaduras (24, 25) configuradas en el cuerpo cilíndrico, que constituyen los al menos dos resortes helic
