DYNAMIC MOTION SPINAL STABILIZATION SYSTEM AND DEVICE

摘要

Provided are a system and device for dynamically stabilizing a spine. In one example, the device includes one member having one end configured to rotatably couple to a bone anchor and another end having a curved channel. Another member of the device has one end configured to rotatably couple to another bone anchor and another end having a curved shaft positioned at least partially within the curved channel. A curvature of the curved channel and curved shaft restrains relative movement of the two members to a three dimensional curved surface.
