replacing nucleus pulposus?

[helmut]

i had my first disectomy in may of 07, after about 6 years of repeating episodes of excruciating pain down my left leg. sitting, during those years was never really an option. MRI showed a very large bulge pressing on the nerve. finally after years of chiropractors the surgery in 07 removed the bulge and i was fine. it was quite perfect, simple mechanics, bulge presses on nerve, remove the bulge ... no more pain ... and i regretted not having done it way earlier. Then 2 years later it started again on my right side, not as painful by far but after about 10 months of it it grew to be pretty uncomfortable again. so i went to see the same surgeon again (who in the meantime also removed part of my right meniscus succesfully) and the MRI showed an almost exact mirrorimage of the previous one. Basically same situation, bulge presses on nerve... etc. so we decided to again remove the bulge, only this time when they removed the bulge, a hole must have opened in the annulus and the nucleus pretty much spilled out. i wasn't happy to hear about that as my "flat tire" just had gotten even flatter. now my mind is spinning. the doctor says that the nucleus would dry up eventually anyways and at least it can no longer cause the disc to bulge but that eventual diminished disc height can cause trouble down the line. my sense of mechanics tells me that i should avoid somehow for the remaining disc wall (annulus)b to be slowly crushed by my bodyweight.

I would love to hear some opinions on what I could?should do. It would seem logical to inject something solid forming, into the space where the nucleus was. wouldn't it?

Thanks,

Nucleus replacement technology has been around for several years. It will not be spread worldwide for at least next 5 years. You should choose something safer that is tested and proved.

Yeah, it does seem farfetched at this point and considering that my annulus is already damaged I would be having little success most likely.

My research at this point has brought me to 2 places, one is Dr. Bertagnoli and the other is Stenum. Dr. Bertagnoli has a device on his website called Barricaid which seems very interesting as it is designed to keep the remaining annulus in place but also keep the discspace from collapsing, so in a way that would provide a mechanical replacement for the nucleus.
Stenum has the M6 which they consider a fantastic new product and considering all the success this site has to report about stenum I am tempted to go with them as well.
My logic and sense of mechanics tell me that ADR could turn problematic due to fusing a organic element, the bone, with an inorganic one. How can such a fusion last for deades? What if the bone deteriorates, wouldnt that naturally affect the bond between the AD and the vertebrae?
Thats why the Barricaid sounds good as it basically keeps the natural bond of the annulus in place but adds the help of a mechanical device to keep discspace in check.

Any opinions out there

Thanks,

I want to know more about this.
