20100204736 | DYNAMIC STABILIZATION DEVICE FOR BONES, IN PARTICULAR FOR VERTEBRAE - A dynamic stabilization device for bones, in particular vertebrae, is made with two bone anchoring elements and a rigid rod with a longitudinal axis connecting them. An elastic element is inserted between the two bone anchoring elements. It acts on the bone anchoring elements to exert a force in a direction of the longitudinal axis. Each bone anchoring element has a first section to be anchored in a bone and a second section to be connected to the rod. At least one of the bone anchoring elements is fixedly connected to the rod to prevent translational movement of the rod relative to it. Further, at least one of the bone anchoring elements is a polyaxial bone screw. Also disclosed is a method for stabilizing vertebrae adjacent to a defective intervertebral disc. A dynamic stabilization device is provided. The anchoring elements are attached to two vertebrae on opposite sides of the defective intervertebral disc. Then, the bone anchoring elements are alligned to connect the rod therebetween with the elastic element positioned between the bone anchoring elements. Finally, one of the bone anchoring elements is connected fixedly to the rod to prevent translational movement of the rod relative to it. | 08-12-2010 |

20120277810 | INSTRUMENT FOR POSITIONING AN INTERVERTEBRAL IMPLANT FOR THE FUSION BETWEEN TWO VERTEBRAL BODIES OF A VERTEBRAL COLUMN - An instrument positions an intervertebral implant for the fusion between two vertebral bodies of a vertebral column. The instrument may include a handle having a proximal and a distal end, a locking shaft extended from the distal end of the handle, and a grasping head at the distal end of the shaft. The locking shaft may be cannulated, and a stem may be hosted inside the cannulated shaft passing through the handle. The stem may be free to rotate with respect to the locking shaft, or vice versa, while the grasping head may be formed at the distal end of the stem with a couple of prongs or clamps toward the other according to an angular relative rotation of the stem with respect to the locking shaft. The instrument may allow the surgeon to grip a corresponding implant with a simple rotation movement of his hand. | 11-01-2012 |
20120277869 | INTERVERTEBRAL IMPLANT FOR THE FUSION BETWEEN TWO VERTEBRAL BODIES OF A VERTEBRAL COLUMN AND CORRESPONDING POSITIONING INSTRUMENT - An intervertebral implant for the fusion between two vertebral bodies of a vertebral column may include a body having two opposite surfaces and holes or cavities for filling purposes during bone growth, and an engagement portion for receiving a gripping end of a positioning instrument. The engagement portion may be shaped as a splined shaft accessible through an opening of the body. | 11-01-2012 |
