Ok....I put in a call to Boston Scientific waiting for a reply. Here are my thoughts. Stenosis is the formation of bony material that interferes with the opening where the nerves go through, so I am thinking, that if the Vertiflex opens up this area more, this will allow for more bony growth, then if the Vertiflex needs removal the pinch to the nerve with the now extra bony growth would cause intractable pain. I am waiting for a call back from the rep. I will see what he says about this theory. I want to speak with someone who has had the Vertiflex implanted for 2 or 3 years and then have had it removed and I want to see if their pain was significant. I wish some doctor would address my concerns honestly.
