A soft fusion uses a system of screws, rods, and flexible bands. It stabilizes the spine but still allows motion at that levels. It also acts as a spacer and thus takes pressure off the nerve roots. It does not use a bone graft. It is supposed to avoid the complication of stressing the other levels of the spine when a bone fusion is done. Check out the zimmer spine site. They have a lot of information there on the dynesys systrem.
