The dura is typically never deficient. The dura can be scarred to the walls of the canal from prior infection, surgery or immune disorders making the dura “look” deficient.
You had a fusion of your spine 15 years ago but do not mention why. I assume you had a fusion for scoliosis with 11 vertebra and 10 discs fused (two vertebra typically share one disc). X-rays noted broken rods in the fusion region. I assume you had no symptoms prior to the auto accident you describe. You note “MRI and CT showed normal” but I also assume that there was an undiagnosed pseudoarthrosis (lack of fusion) as the normal reason rods break is a pseudoarthrosis.
A surgeon typically would “not repair the spot where the rods were broken” unless there was a lack of fusion. If the surgeon was repairing the pseudoarthrosis, I am unclear why he or she performed a decompression of the canal at the same time as the fusion repair unless there was also a narrowing of the spinal canal (stenosis).
You appear to have developed arachnoiditis from the initial surgery “Failed to mention the Spinal MRI also showed an empty thecal sac with adhesive arachnoiditis in the Lumbar region” This may well be why the second surgeon could not find the dura as it was adhered to the walls of the canal. This also may be why you had lower extremity symptoms prior to the second surgery.
Your Multiple Sclerosis was not caused by either of the two prior surgeries. MS is an autoimmune phenomenon where your immune system attacks the myelin of the nerves.
