Magnetic resonance imaging clarity of the Bryan, Prodisc-C, Prestige LP, and PCM cervical arthroplasty devices.
“ CONCLUSIONS.: Postoperative visualization of neural structures and adjacent levels after cervical arthroplasty is variable among current available devices. Devices containing nontitanium metals (cobalt-chrome-molybdenum alloys in the PCM and Prodisc-C) prevent accurate postoperative assessment with magnetic resonance imaging at the surgical and adjacent levels. Titanium devices, with or without polyethylene (Bryan disc or Prestige LP), allow for satisfactory monitoring of the adjacent and operated levels. This information is crucial for any surgeon who wishes to assess adequacy of neural decompression and where monitoring of adjacent levels is desired.
You are reading and that is good in my limited opinon. Several journal articles cite the above difference, so I agree with the above in general. I am not MRI trained.

There are trade-offs, surgery v. no surgery, waiting time for symptoms to decrease, type of disc replacement, ...

A second medical opinon for surgery will encourage most patients to get serious about it. We can live with a lot of annoyance in life.

You mentioned ProDisc v. Bryan. There are stats/data on the FDA sites, but I did not compare them. The 2012 AANS/CNS annual meeting abstracts might compare them, but it is impossible to put it into a table with the software used on most any internet forum.

The type of disc replacement is of interest. You may want to browse through the FDA documents:

Bryan - FDA Link

The FDA clinical trials compared the Bryan to ACDF (fusion).
2 year overall success rates page 22

95.5% Bryan
85.4% ACDF (Control)

Of the 6 surgeries in the control group performed, 3 or 12% to date were for adjacent level degenerative disease and 1 or 4% for remote level degenerative disc disease. The remaining 2 surgeries were performed on the same patient for a pseudarthrosis. In the investigational group there was only 1 secondary surgery performed to date for adjacent level disease 5%"

I will try to post something about heterotopic ossification in the Articles section.
