Prodisc ADR fusing and not moving

[energyofhope]

Interesting thought, Katie. Is there a specific blood test for nickel allergy?
How do you know about your allergy? From reaction to jewelry?

I don't have any known allergies, but that does not mean I am not allergic to something I don't know about (I am a guy, so I don't wear earrings, maybe if I did, I would discover a nickel allergy

They did all the standard blood work on me before every surgery and it was good enough to send me into space. I did ask them if the material in the Prodiscs may cause rejection or some reaction and they said "no," for whatever that is worth. My disks cemented themselves well and there were no issues with them sliding out, no infection, no excessive swelling, or other red flags, so I don't know what to think.

There may still be a subtle reaction that manifests itself as this fusing over but I have yet to see anything in scientific literature that would shed light on it.

I do know that I am not alone. As more ADR is done, there are more reports of autofusion happening. I, personally, still suspect facet joint hypertrophy as an under-appreciated predisposition for ADR problems down the road. IMHO, from what I've read by now, fusion is probably better than ADR in cases like this.

eOh, I don't think that pre-existing facet issues are under-appreciated as a source of post-adr problems. This is extensively discussed at every meeting and in most presentations about ADR. More severe facet issues are an absolute contra-indication for ADR.

Having said that, the discussions of facet issues also demonstrate the unpredictability of spine surgery. I've seen cases presented with grade III facets pre-pop in which the facets have recovered and improved in the years following ADR. (Facets are graded I to IV with grade III representing moderate to severe degeneration, IV being severe.). I have also seen cases presented where pre-op good facets go bad after ADR.

Some might make an assumption that the cases going bad after ADR would have been successful if a fusion was done instead of ADR. In the discussions we had regarding failed back surgery syndrome with Dr. Hochschuler of TBI at the GPN symposium, he reiterated what I hear at all the conferences. "A very high percentage of the patients that fail ADR would have likely failed with fusion as well." (<-- paraphrased by mmglobal) This is evidenced by the number of cases in which the patient has an apparently successful ADR surgery that they tolerate well and recover from well... they just do poorly on all clinical outcome measurements. This is followed by an apparent successful fusion that they tolerate well and recover from well... but they just to poorly on all clinical outcome measurements.

I have seen many successful fusions in the patient community... both as a first surgery and as a revision for failed ADR surgery. Yes, the facets are key players in many failed surgeries. I think that 2 things are very clear:

1. Either we don't yet understand the system well enough and there (currently) no way to effectively predict success/failure for any/most spine procedures... or:

2. There is a randomness of failures that will never be understood...

I have a theory that I've been discussing with the spine surgeons for years. Most of them will first laugh at it, then they will agree with it:

All major spine procedures come with a success rate that is at best, about 85%.As the technologies develop, we get improvements in the system and get better and better options. I believe that 15 years from now, what we do today will seem barbaric and outdated... but the success rates will still be 85%!

Energy, I got the information and hint of possible allergy problems from people on here and another board. Liz recommended I look up another person's post about her problems after ADR surgery, and it made a lot of sense to me.

Here's the link. Check out Carrie's post half way down the page. Her story carries on through several pages.
Lumbar L5/S1 - Surgery Failed, Advice Needed (carrief) - Page 2 - ADRSupport Community

Here is the email address to Rush University where I am getting the blood test. Just Google the information you find in Carrie's posts. Marco_Caicedo at rush.edu (Just change the @ sign and join things together )

Yes, I am allergic to most jewelery unfortunately. No dressing up for me

I've also developed quite a number of sensitivities to food and related chemicals (preservatives, etc.), plus environmental 'stuff' over the past year, which I think are related to the massive amounts of narcotics I am taking. My allergist thinks that my immune system has taken a tailspin. While I can't eat any grains, I've had all the testing and am not positive for Celiac disease. The reactions are bad enough that I need to use and carry two Epi-pens and have been in the hospital by ambulance three times.

Here's another thought about your problem. Would your surgeon have carved down the end face of the vertebrae to make room for the ADR? Maybe that could have promoted an accelerated bone growth?

I have very little medical training, just some health sciences stuff. Peanuts in the face of all this, so take this with a grain of salt. I have found the experiences of others to be a great tool for educating myself though.

Good luck with everything. When it comes to things like this, nothing is too weird to investigate

Thank you all for your input!

Katie, your information about Carrie is very interesting! Thank you.

I did not experience the symptoms Carrie described nor did I have any of the red flags that would point at a metal allergy after ADR implantation. But, never say never. I will definitely bring up metal allergy testing with my doctors.

I also need to find out if this test is covered by Medicare (in the U.S.)

Does anyone know?

[Katie]

Liz deserves all the credit She pointed out that thread to me, and brought the metal allergy question to the forefront. While I always had it in the back of my mind, since I have so many new allergies on top of nickel, she really made me take a hard look at it.

It is just 'pay it forward' time I really hope you get to the bottom of this soon.

Though I doubt this will work for metal allergies - a home remedy for indoor and outdoor allergies is a tablespoon of honey and applecider vineger daily. I've since forgotten what the applecider does but the honey contains small amounts of most allergens, slowly building up your own immunities.

I premix them, keep them in a jar in frig and add 2 tablespoons to a class of orange juice. Warning - this is a very slow process, taking about 1 year before you realize the benefit.
