Do patients with spinal canal stenosis experience spontaneous quadriparesis without an injury?
Unlikely without injury
I went through the attached report. It says about mild to moderate lower thoracic spinal stenosis. I do not see any stenosis of cervical or lumbar spinal vertebrae to have paresis.
Although I do not have research on this kind of case, it is unthinkable to have quadriparesis in such people. Second spontaneous weakness or paralysis without injury is uncommon.
Quadriparesis is paralysis of all the four limbs which can never happen in thoracic spinal stenosis.
More over stenosis is restricted to T10-11 vertebrae which do not innervate lower limbs as well.
So paresis is distant. If the present stenosis progresses upwards into the upper thoracic vertebra there would be restrict of movements and paralysis of respiratory muscles which is quite serious.
So do not think about paresis but restriction of respiratory muscle movement is key.
Hope I made it clear.
I think the fusion was delayed in the case.
It is very common to see respiratory failure following spinal fusion.
It is good that the patient is breathing on his own. That means the thoracic spine stenosis is not quickly progressing. Since the thoracic spine does not move the chances of respiratory muscle paralysis is low.
I am not sure if the quadriparesis would recover. Rehabilitation is the only alternative without functional compromise.
The fusion was warranted before the event.
