If you've been researching disc replacement as an alternative to spinal fusion, you may have come across the idea that disc replacement is “experimental". You might have even see it in writing, in an insurance coverage decision or a denial letter.
Dr. Alex Sielatycki, an orthopedic spine surgeon, says disc replacement is not experimental. Disc replacement has been around for more than twenty years and has gone through rigorous testing and long-term follow-up. In studies, disc replacement has been found to be at least equivalent, if not superior, to spinal fusion, which is still the standard of care for chronic neck, arm, leg, and back pain.
Not every spine surgeon performs disc replacement, but a surgeon not offering a procedure isn't evidence that the procedure is unproven.
So if you hear that disc replacement is experimental, ask directly why they believe that and whether they have data to support it.
