Have either of you looked into the new replacement disks that are now in
medical trials? I have several degenerated disks that I'm simply living
with so far and keeping at bay with exercise (I've forgotten what it is
like to be pain free) as I really don't want to lose mobility which occurs
with a fusion procedure.

I've been casually following these devices a hoping they become mainstream
before I can't take it any longer and have to do something.

Yes, and the candidate field is rather narrow. In my case, I was not a
candidate because of previous traditional surgery. Now, it is fused at that
level, so nothing else can be done, there.

From how it was explained to me, the level that would be replaced has to be
undisturbed by previous surgeries. The surrounding and muscle and
everything has to be strong, because that is all that holds the new disc in
place.

I wish that would have been an option, but it was not around when I had my
first surgery done.

That is my understanding also. That is one of the big reasons I'm
holding out.

That isn't quite my understanding, but my understanding is admittedly
feeble in this area. What I've read says that they remove the OEM disk
and then cut away part of each surrounding vertebrate. The artificial
disk unit has essentially a partial titanium vertebrate on each side of
the polymer disk. This is glued (maybe also screwed, I don't know) to
the OEM bone vertebrate much the way artificial hips and knees are put
in. In this scenario, I'm not sure why they couldn't break apart a
fused area, but maybe it is simply too aggressive a procedure to do with
the spinal cord in the middle.

Well, that is a bummer, but you did what you had to do when you had to
do it. Can't look back.

That sounds like a new technology disc, than the ones I looked at a couple
of years ago; they just sat in there, held in by the surrounding soft
tissue. That isn't surprising; medical tech move at a very fast rate.

I would think the amount of bone added in the fusion is the biggest factor.
Basically, all the space that the normal disc occupied, is filled with bone,
now. That would be a lot to remove, especially like you said, right next to
the spinal chord.
