Dear Sarah.
Reading your post today has filled me with both great sadness and frustration!
Sadness:
I am so very sad that you are still suffering so much, after such a long time, and after your 2 operations. I am also very sad that the new realisation and diagnosis of your present condition, is so poor! Many of us here understand and feel what your going through! I am also sad that you are still not sure how to proceed in future.
Frustration:
I truly believe that your Surgeon, does not deserve your kind words, faith or admiration.
Oh, I'm sure he/she is nice, kind and holds the relevant medical qualifications for his/her role, but, (and i'm very sorry to be so blunt Sarah) I believe that everyone should seriously question, any Surgeon's treatment pathway plan when (within 12 months or so) it goes from prioritising a minimal, low invasive and revesable approach to release you from the hell of your spinal pain, to a 'blunderbus' of a procedure, that is normally a highly invasive, very destructive and is (I believe) an irriversible procedure. In my opinion, It should only be considered as a last resort! (If irriversability is incorrect, I would appricate information from members)
I am not sure if you have just forgotten the name of the device used in you 1st procedure Sarah, or whether it's name was never told to by your Surgeon, in my experience, I found this very common, but I think it would have been something like a Wallace Stablisition Device or the more widely used X-stop. Basically, both are designed to to increase the gap between the vertibrae and thereby decompressing the disc and reducing the risk of nerve impingement by both bone and disc material. They are also designed to reduce the amount of backward extension, thereby reducing the contact between nerve and bone in the dorsal and foraminal areas.
They are both 'stop gap' devices and are meant to be removable, in order to replace them when they fail, wear out 'or' in order to upgrade to newer devices in the future. They are not a 'cure' and dont cure osteoarthritis, disc herniations and so on. Did yours fail or were there other problems?
I appologise again for my forthrightness Sarah, but in the world of back pain, knowledge helps our understanding of our conditions, although I must admit, it does not always gurantee the best clinical outcomes for us suffers. I would respectfully ask you to seek a 'second opinion' before committing to any further procedures! kvdp and Keano (below) both raise good points, you need much more information than you seem to have at present, before making any further decisions or commitments.
Please contiue to read the threads on the HP back problems pages, as some of the answers you seek, may already be posted, and don't forget Sarah, we are all here together!
Best wishes
