They were either referring to vertebral instability, where the vertebrae may not line up, and part of the spinal cord is compressed there, or there may be a herniated disk that is compressing on the spinal cord. You cannot see the spinal cord on an x-ray, though, because it has the same density as the fluid that surrounds it. You can only really diagnose it with an MRI or CT scan accurately. Again, compression on the spinal cord would not cause generalized disorientation. It would affect the limbs, depending on the location. It wouldn't be a bad idea to have a radiologist look at the x-rays. I probably wouldn't pursue referral to a neurologist quite yet, though. If his symptoms are improving, there is nothing wrong with just monitoring him. Hope this helps.
