Cervical spine fusion

Hi, I have had RA now for 40+ years and have had several operations in that time. I have both wrists fused, a total elbow replacement and are having Infliximab infusions every 6 weeks. I take Mtx and other anti-Inflammatories and pain relief drugs. I had a MRI recently on my spine due to excessive pain in my neck which I have had for a couple of years and although I kept telling my Rheumy nurse of this pain she seemed to be reluctant to do anything about it until more recently. They have found that I have excessive wear in the cervical area and the discs are almost non existent. So the cervical vertebrae are bone on bone with spur extensions that are putting pressure on the spinal cord. I have been offered a full cervical fusion or a series of injections first to see if this will relieve some of the pain. I have accepted the injections as I am hoping that this will give me the relief I need without having to have this dramatic operation which will make my neck rigid. I guess that in time I will have to have this op' as I believe the injections will only be a temporary measure and will not last indefinitely. Has anyone else been faced with this decision and what was the outcome. I would love to hear your experiences. Thank you, Brian
