Doctors like Dr. Johans will often attempt to recommend a disc replacement over a fusion for the same reason you would not fuse a hip or knee joint. The range of motion these joints have leads to a more enjoyable experience than if they could not move. This artificial disc helps maintain regular joint motion, just like when it was healthy and new. The new disc also helps reduce inflammation and pain that a fusion can cause so that you can enjoy greater flexibility, stability, and discomfort relief. Additionally, since the replaced disc is designed to move as your original one did, it can provide better balance and coordination in everyday activities. Ultimately, a disc replacement returns things to how they were originally meant to be - much more functional.
