Update:. Last week she had the surgery, and so far, it has been extremely successful. Surgeon used a prodisc-c (the video is fascinating). It is a t shaped device with a ball and socket. I had expected the "hockey puck" style rather than this, so I am very pleased. The surgeon said that the placement was perfect and looking at the X-ray it certainly looks that way.
Pain has already gone from her arms and chest and feeling and strength is already returning in her hands. She has an incision in the front only, they did not go through the back of the neck at all.
She does have significant pain in her shoulders, back and rear of neck and the bruising is beginning to surface. She is doing her best to limit meds only for when. She feels she needs them (staying off oxy as much as possible).
So far, very pleased. Feel very blessed to have family that have been helping her around the house whilst I am at work and taking our disabled dog out for us.
