DYNAMIC ANCHORING DEVICE AND DYNAMIC STABILIZING DEVICE, WHICH SERVES TO STABILIZE BONES, PARTICULARLY VERTEBRAE, AND WHICH HAS AN ANCHORING DEVICE OF THIS TYPE |
摘要 |
<p>A dynamic anchoring device is described. An element with a shank for anchoring in a bone or a vertebra and with a head connected to the shank is provided with a receiving part for the head and with an elastomeric pressure element acting on the head. The pressure element is formed and located in such a way that, upon a movement of the element from a first angular position of the shank relative to the receiving part into a second angular position, it exerts a return force on the head. Further, a dynamic stabilization device, in particular for vertebrae, is provided. In such a stabilization device, a rod is connected two anchoring devices. At least one of the anchoring devices is constructed as dynamic anchoring element.</p> |
