DYNAMIC STABILIZATION DEVICES AND METHODS |
摘要 |
A dynamic stabilization device includes end caps that define a bore for receiving a corresponding bone screw therethrough. A spacer is engaged between each end cap and a cable passes through each of the components and is placed in tension to couple the spacer between the two end caps. The spacer is formed of a material that allows some flexible movement after implantation. An alternative stabilization device includes a spacer over- molded about two bushings defining the bores. According to a method of use, a stabilization device is passed along guide wires through a small incision. Once the device is in contact with the vertebrae, the bone screws are advanced along the guide wires and driven into the bone. One fastener bore may include a camming surface that causes distraction of the vertebrae as the bone screw is threaded into the vertebral bone.
