摘要:
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.
