    • 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。
