    摘要: A functionally dynamic stabilization unit and system for treatment of spinal instability are provided. Each unit, and collectively, the system, is configured to control flexion, extension and translation of the affected unstable vertebral area, thereby stabilizing the vertebral segments by restoring normal function. This is achieved by providing a unit and system that allow for lateral bending, axial compression, rotation, anterior segmental height adjustment, and posterior segmental height adjustment. The unit and system provide sufficient segmental stiffness, while also limiting, or controlling, the range of motion (i.e., sufficient stiffness in the neutral or active zone, while limiting or preventing motion outside of the active zone) to stabilize the vertebral segments. In use, the system mimics the natural movement of the normal spine. Furthermore, the system includes a rigid, fusion-promoting coupler configured for use in an adjacent level, or as a substitute for the functionally dynamic unit. The modularity of the system allows adjustment over time and easier revision surgery, and is configured for minimally-invasive, delivery or implantation.

    摘要: The invention relates to the preparation of an intervertebral space with a trial implant (9), the insertion of an implant (5, 6, 7), the inserters (13, 16), and the method for feeding and inserting the implant (5, 6, 7) by means of an oblique anterior approach. In the novel improved method, the associated instruments (13, 16) for inserting an implant (5, 6, 7) into an intervertebral space, in particular for the lumbar spine at an oblique anterior angle of 45° was developed, the left side of the body being preferred for insertion of the implant (5, 6, 7). Either the implant (5, 6, 7) can be inserted all in one, or first the upper part (5) and lower parts (7) and then the inlay (6) may be inserted. By insertion by means of the left oblique anterior approach at 45°, optimum utilization of the area of the intervertebral space is ensured (footprint), and better retention of the implant is guaranteed by the exact chiselling at an angle of 90° normal to the respective intervertebral surface.

    摘要: A method of limiting the movability of an intervertebral disk prosthesis with regard to pivoting movements, and an intervertebral disk prosthesis. The method includes the step of asymmetrically limiting at least one of a flexion-extension movement, a lateral bending, and a rotation about a vertical axis in order to limit the movability of the prosthesis. The prosthesis comprises articulated prosthesis components, and movement-limitation measures configured to limit movability of the components with respect to flexion-extension movement, lateral bending and a rotation about a vertical axis of the prosthesis in a defined manner.

    摘要: A method for distracting at least two adjacent vertebrae and/or retaining them in a spaced apart position. Anchor screws are secured to the adjacent vertebrae and tubes of a retainer-distracter instrument frame are slid down over the anchor screws, after which the anchor screws are positively secured to the tubes of the frame. The frame includes a structure for moving the arms and hence the anchor screws and vertebrae toward and away from each other. After the anchor screws and frame are attached, a separate distracter distracts the vertebrae away from each other, whereupon the instrument acts only as a retainer to hold the vertebrae apart.
