I have another thread on here on how my pro disc pops and clicks. My surgeon found out the acceptable 4° of extra motion is NOT allowable in my body. Words of my surgeon "...as usual Mr Mar**** you are the exception to every rule".
The fact of the matter is anytime they try something I'm in the 10% that gets worse or fails.
He noted, the way my spine is built that the 4° is actually too much extra motion and is causing the spinous process' to click on the surrounding process' and tissue.
SO now the deal is my surgeon believes that a spinous process fixation device at the pro-disc level will do something similar to a 60% fusion and it's reversible. here is a pichttp://www.alltecsurgical.com/images/aspen.jpg
