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.
摘要翻译： 提供了用于治疗脊柱不稳定性的功能性动态稳定单元和系统。 每个单位，并且统称为系统，被配置为控制受影响的不稳定脊椎区域的屈曲，伸展和平移，从而通过恢复正常功能来稳定椎骨段。 这是通过提供允许横向弯曲，轴向压缩，旋转，前节段高度调节和后部段高度调节的单元和系统来实现的。 该单元和系统提供足够的节段刚度，同时还限制或控制运动范围（即，中性或活动区域中的足够的刚度，同时限制或防止活动区域外的运动）以稳定椎骨段。 在使用中，系统模仿正常脊柱的自然运动。 此外，该系统包括被配置为用于相邻级别的刚性，融合促进耦合器，或者作为功能动态单元的替代。 该系统的模块化允许随着时间的推移进行调整，并且更容易进行修复手术，并且被配置用于微创，输送或植入。

摘要： A knee joint for a leg prosthesis comprising an upper joint part (2) and a lower joint part (3) which can be rotated about a joint axis (5) relative to the upper part of the joint (2), and an upper brake device (14, 15, 20, 21). The brake device comprises a first force transmission element 14, upon which the force triggering the brake effect acts, and which transfers the force at a given transmission ratio to a second force transmission element (15), which, in relation to the joint axis, transfers the displaced force in a substantially parallel direction towards a brake disc (20, 21).
