Medical research and clinical studies have shown that a lumbar disc replacement typically has a high success rate of 88%. The FDA has gone on record stating that the success rate average is about 90%, with the average replacement disk averaging a 70-year lifespan. While alternatives such as spinal fusion surgery have a success rate between 70-90%, disc replacement has shown to be a more effective and reliable procedure. For many, this makes it the preferred option as it shows more consistent results across the board.
