    • Spine stabilization systems are disclosed. One spine stabilization system includes a bone screw assembly including a coupling member and a screw member received therein. The coupling member includes a pair of extension elements that form a pair of slots. The slots include bottom angled surfaces. An angled wedge member having a substantially horizontal bottom surface and an angled top surface is delivered on top of the screw member within the coupling member. A rod member can be delivered down the coupling member such that it rests on the slots and on top of the angled wedge member. A locking assembly comprising a cap member and set screw can be delivered down the coupling member to secure the rod member to the coupling member. The rod member and locking assembly components can be delivered through a single incision and at a same or similar angle as the screw member during surgery.
    • 公开了脊柱稳定系统。 一个脊柱稳定系统包括骨螺钉组件,其包括联接构件和容纳在其中的螺钉构件。 联接构件包括形成一对狭槽的一对延伸元件。 插槽包括底部倾斜的表面。 具有基本上水平的底表面和成角度的顶表面的成角度的楔形构件在联接构件内的螺钉构件的顶部上被输送。 杆构件可以沿着联接构件传送,使得其支撑在狭槽上并且在倾斜的楔形构件的顶部上。 包括盖构件和固定螺钉的锁定组件可以沿着联接构件递送以将杆构件固定到联接构件。 杆构件和锁定组件部件可以在手术期间通过单个切口和与螺钉构件相同或相似的角度被输送。

    • A spinal stabilization system for surgical implantation in the spine having a bone fastener. The bone fastener is provided with a head portion and a shaft portion. A housing is also provided with a recess defined by sidewalls and an opening for receiving the head portion of the bone fastener. A seating element is disposed within the housing and positioned over the head portion of the bone fastener. An elongate rod is positioned on the seating element within the recess of the housing. The system also includes a cap capable of engaging with a top portion of the housing and capturing the elongate rod within the recess of the housing when the cap is rotated. The bone fastener articulates in a single plane with respect to the housing and the seat element.
    • 一种用于在具有骨紧固件的脊柱中进行手术植入的脊柱稳定系统。 骨紧固件设置有头部和轴部。 壳体还设置有由侧壁限定的凹部和用于接收骨紧固件的头部的开口。 座部元件设置在壳体内并且定位在骨紧固件的头部之上。 细长的杆位于壳体的凹部内的座椅元件上。 该系统还包括能够与壳体的顶部接合并且当盖旋转时将细长杆捕获在壳体的凹部内的盖。 骨紧固件相对于壳体和座椅元件在单个平面中铰接。
