Tom,
My gut feeling is that you need to gather up all your pre surgery MRI, x-rays and any other tests that where done before surgery,
Also get your surgical reports and all the post surgery MRI, CT and x-ray films and get another opinion or even 2 or 3 other opinions as to what is going on now.
I would be looking for the best you can find in both an orthopedic as well as neurosurgeon that specialize in spines to seek other opinions.
A fresh pair of eyes on all of these results and knowing exactly what the spinal surgeon did in the OR is a good idea.
It's unfortunate that it happens but it is far too common, that a surgeon of any kind is reluctant or refuses to admit that there is something wrong with the surgery that he/she did.
It isn't just spinal surgeons, but doctors just don't want to admit that they are wrong or that they are unable to see anything wrong and suggest that you seek the opinion of another surgeon, or doctor for that matter.
In my own personal experience, I have found far too many spinal surgeons and even just orthopedic surgeons that specialize in various orthopedic problems are unable to read an MRI and base their entire opinion on the doctor that reads the MRI or CT or x-ray scans. That to me is criminal and should be required to be an ortho or spinal surgeon.
Possible problems that are causing your pain, could very well be a damaged nerve, but there are still reasons for it and possible things that can be done to prevent the continued pain you are having. But doing just the nerve tests only gives answers about the nerve and not a cause.
Though I am not saying that any of these following possibilities are the cause and I AM NOT A DOCTOR OR EVEN IN THE MEDICAL FIELD, I JUST DO KNOW SOME MEDICAL INFORMATION AND I DO PERSONALLY KNOW PEOPLE WHO HAVE HAD THE FOLLOWING PROBLEMS POST FUSION AND HAD TO SPEND A LOT OF TIME RESEARCHING AND GOING TO DIFFERENT DOCTORS FOR OPINIONS TO FIND THE CAUSE OF VERY SIMILAR OR THE SAME POST FUSION PROBLEMS.
I would be wanting to know if any of the following could be the cause of the pain you have now.
1. The most common cause of failed spinal surgery for nerve decompression, especially in the lumbar spine and also not always done with a fusion of the lumbar area is the widening of the lateral recess. If this is not done, even with a fusion, then the nerves can become entrapped in the lateral recess and then pain from the nerves will return and spread down the back butt, back of thigh and down through the leg, ankle and feet. Until this area is addressed it will not stop the pain.
2. Where the proper size screws, rods and cages used and are they still in place or have the moved and are causing pressure on the nerves.
3. Are there any bone fragments that where not removed during surgery and they are pressing on the nerves and starting to fuse with the fusing process.
4. Is there overgrowth of the bone that can happen and that is pressing on nerves. This can sometimes happen if BMP (bone morphogenic proteing) and becomes a problem in the formation of scar tissue.
5. Is there scar tissue forming that is wrapping around the S1 nerve and now causing the problem that you are having.
AGAIN, I AM NOT SAYING THAT ANY OF THESE ARE CAUSING THE PAIN YOU ARE HAVING, BUT THEY ARE POSSIBILITIES THAT COULD BE CAUSING IT.
They are things that should be checked into and the best way to have that done is with another, fresh pair of eyes looking at everything. I.E a new spinal surgeon.
One of the reasons that I suggest the above issues as a problem is I have a friend who lives in the midwest area and had the same surgery you had with the same hardware used.
She was doing fine post op for several months and then all the problems returned, with pain just like yours.
He return visits to her spinal surgeon, whom I might add was not of her choice but rather a WC spinal surgeon that she had to use, could not find anything wrong.
Same as yours.
All the same repeat tests where done and EMG for nerves.
Now this woman is in her late 30's and was an active nurse in a busy city ER.
The surgeons only suggestion was to have a SCS (spinal cord stimulator) permanently implanted to deal with the pain and retire from her career and live with the pain.
She was so desperate for pain relief, she has young children and was injured at work, that she decided to give the SCS a trial run before the permanent one was implanted. She had instant relief of pain for about 2 weeks before the temporary SCS was removed and she had to wait a month for the permanent one to be implanted.
During that time I was finally able to get her to fight WC and get a second opinion with another spinal surgeon.
WC agreed to pay for the second opinion because it was a lot cheaper to do that and maybe find out that she needed more surgery, which would also be cheaper than over $250,000 for the SCS implant.
A second set of eyes on her films had the second opinion doctor figuring out what was wrong, but to be sure that the S1 nerve was involved he did a brief diagnostic nerve block to the S1 nerve, using a small amount of lidocaine. She was with total pain relief for 2 hours. He also had a fresh set of MRI pics and CT scan done as well. He felt the MRI and CT scans she had done where not clear enough.
He found that the wrong size screw was used and the cage had moved. and there was scar tissue wrapped around the S1 nerve caused by bone fragments that where left.
She had surgery with this new spine surgeon a few days later. He removed the screw and cage, removed the scar tissue wrapped around the bone fragments on the S1 nerve.
10 weeks later she was back at work part time with no pain and going through PT.
It's know about 20 weeks post her revision surgery and she is back at work full time and has no pain problems.
All because she got a second set of eyes on everything and she almost settled for a life of pain with an SCS and retiring from nursing.
Tom, go get another set of eyes on all those films and see what you can find out.
Best of luck and keep us posted on all that happens.
