    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the adjacent vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion dynamically connected to a second rod portion at a retainer that has separate chambers for receiving rod portions. One rod portion is configured for longitudinal movement and the other rod portion is configured for polyaxial angulation relative to the retainer. The dynamic rod is configured such that the retainer is located proximate to one of the facet joints when implanted into a patient. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion, extension and rotation moments of the spine.
    • 提供了植入患者体内并可在相邻椎体内的两个椎骨锚固件之间连接的动态杆。 动态杆将相邻的椎体以动态方式固定在一起,提供立即的术后稳定性和支撑脊柱。 动态杆包括在保持器处动态地连接到第二杆部分的第一杆部分,其具有用于接收杆部分的单独的室。 一个杆部分构造成用于纵向移动,另一个杆部分构造成相对于保持器进行多轴成角度。 动态杆被构造成使得当植入患者时保持器位于小面关节之一附近。 动态杆允许第一和第二杆部分的相对运动,允许杆承载脊柱的一些自然弯曲,伸展和旋转力矩。

    • An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a receiving portion configured for seating a spinous process of a scoliotic spine or a spine with misaligned spinous processes. Each arm has a proximal caming surface and is capable of rotation with respect to the body. An actuator assembly is disposed inside the passageway and connected to the body. When advanced, a threaded shaft of the actuator assembly contacts the caming surfaces of arms to rotate them from an undeployed to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the superior and inferior arms of the spacer. Variations adapted for scoliotic curves are provided.
    • 提供了用于放置在脊柱运动节段中的相邻棘突之间的可植入间隔物。 间隔件包括限定纵向通道的主体。 第一臂和第二臂连接到身体。 每个臂具有一对延伸部和鞍座,该鞍座限定接收部分,该接收部分被配置为用于安置具有未对准的棘突的脊柱侧凸脊柱或脊柱的棘突。 每个臂具有近侧凸起表面并且能够相对于身体旋转。 致动器组件布置在通道内并连接到本体。 当推进时,致动器组件的螺纹轴接触臂的凸轮表面以使它们从未展开状态转变为展开状态。 在展开构型中,分散的相邻棘突坐落在间隔器的上臂和下臂中。 提供适用于侧弯曲线的变化。
