X-Stop Interspinous Spacers?

[lyndies]

Hi Paul,

I also have multi level Mobi-C implanted at C4-5, C5-6 which were placed in 2008. I am curious to know how they shifted after 3 years as I thought they fused into the vertebrae. I also have progressive radiating nerve pain from my neck into upper extremity with continued loss of strength and feeling, but Dr. Zigler at the Texas Spine Institute tells me everything looks great.

After reading your post, I am very curious to know how the shift occurred.

Thanks and I hope you find the relief you are looking for.

IMHO, multi-level constructs are not good candidates for mobile core devices. (Spinal Kinetics M6, mobi-c, mobi-l, Charite, .... ) If you search ispine for the words "tiddley winks", you should find my description of how if something pushes one core in one direction, it can cause the adjacent level cores to be pushed in the opposite direction. This sets up a configuration that is not secure and the problems at each level multiplies the problems at the next level. I've seen too many of these configurations require revision.

Please note that I have a 2-level Charite' with no problems. Properly implanted in a stable spine, they are fine. Unfortunately, it's too easy to have a problem with this configuration and a problem with multi-level mobile-core ADR's are much worse than the corresponding multi-level stationary core configurations. If you have this (as I do) and are doing well, don't look a gift horse in the mouth... you are fine. However, if you are considering multi-level ADR, consider the mobile core issue very carefully.
