    • A posterior spinal fusion system may include pedicle screws and one or more segments designed to be attached to the implanted pedicle screws via nuts to fuse spinal motion segments in a modular fashion. The pedicle screws may have semispherical receiving surfaces, and each segment may have mounting portions at both ends, with corresponding semispherical engagement surfaces. The nuts may also have semispherical surfaces. The semispherical surfaces permit polyaxial adjustment of the relative orientations of the segments and pedicle screws. Each mounting portion may have a passageway therethrough to receive the proximal end of the corresponding pedicle screw; each passageway may intersect the edge of the corresponding engagement surface to facilitate percutaneous placement. Such placement may be carried out through cannulae to provide a minimally invasive (MIS) implantation procedure.
    • 后部脊柱融合系统可以包括椎弓根螺钉和一个或多个设计成通过螺母连接到植入的椎弓根螺钉上的节段,以模块化方式融合脊柱运动节段。 椎弓根螺钉可以具有半球形接收表面,并且每个部分可以在两端具有相应的半球形接合表面的安装部分。 螺母也可以具有半球面。 半球形表面允许多段调节片段和椎弓根螺钉的相对取向。 每个安装部分可以具有通过其的通道,以容纳对应的椎弓根螺钉的近端; 每个通道可以与相应的接合表面的边缘相交以便于经皮放置。 这种放置可以通过套管进行以提供微创(MIS)植入程序。

    • An intervertebral stabilization device and method is disclosed. The device preferably includes a planar spring enclosed within a housing. The housing is joined to an articulation component at either end, and the articulation components have couplings connectable to anchoring components which are securable to adjacent vertebrae. The planar spring can flex and retract providing relative motion between the adjacent vertebrae. The articulation components are ball and socket joints which allow the entire assembly to flexibly follow the curvature of the spine. A fusion rod with articulation components and couplings at either end may be substituted for the spring device. The couplings enable interchangeability between a fusion rod assembly and spring assembly, so that dynamic stabilization can occur at one vertebral level and fusion at the adjacent vertebral level. An overhung spring assembly with a sideways displaced housing which allows for a shorter pedicle to pedicle displacement is also disclosed.
    • 公开了一种椎间稳定装置和方法。 该装置优选地包括封装在壳体内的平面弹簧。 壳体在任一端连接到关节元件,并且关节元件具有可连接到相邻椎骨上的锚固部件的联接件。 平面弹簧可以弯曲和缩回,提供相邻椎骨之间的相对运动。 铰接部件是球窝接头,允许整个组件灵活地跟随脊柱的曲率。 在任一端具有铰接部件和联轴器的熔接杆可以代替弹簧装置。 联轴器使得熔接杆组件和弹簧组件之间可互换,使得动态稳定可以在一个椎体水平处发生并且在相邻椎骨水平处发生融合。 还公开了一种具有允许较短椎弓根向椎弓根移位的侧向移位的外壳的悬臂弹簧组件。

    • A modular implant for stabilizing the relative motion of spinal vertebrae comprises at least two pairs of plates which connect to two adjacent spinous processes, a spacer configured to be positioned between the spinous processes, and a fastener which pivotably connects to the plates and the spacer. The spacer is interchangeable and may comprise a variety of materials, each providing a different level of elasticity to the spinous processes. Relative motion between vertebrae can also be controlled by varying the surface configuration of the plates and by varying threading of the fastener. Several implants may be linked to provide stabilization across multiple vertebral levels, and the relative motion provided at each vertebral level may differ. A method for revising the implant is provided which comprises accessing the implant and replacing the spacer.
    • 用于稳定脊椎椎体的相对运动的模块化植入物包括连接到两个相邻棘突的至少两对板,被配置为定位在棘突之间的间隔件和可枢转地连接到板和间隔件的紧固件。 间隔物是可互换的并且可以包括各种各样的材料,每种材料提供与棘突不同的弹性水平。 椎骨之间的相对运动也可以通过改变板的表面形状和通过改变紧固件的螺纹来控制。 可以将多个植入物连接以提供跨多个椎骨水平的稳定性,并且在每个椎骨水平处提供的相对运动可以不同。 提供了修改植入物的方法,其包括进入植入物并且更换间隔物。
