摘要：
The present application is directed to methods and devices that provide for asymmetrical movement of vertebral members. In one embodiment, first and second anchors connect the rod to the vertebral members. The rod may be fixedly connected to the first anchor, and movably connected to the second anchor. A limiting device may be positioned on one or both sides of the second anchor. The limiting device or devices control an extent of movement between the rod and the second anchor during vertebral motion. In one embodiment, the device controls an amount of flexion and extension of the vertebral members.
