The images indicate that your father has severe central stenosis and cord injury. Does he have any of the spinal cord injury signs that I previously indicated (long tract signs like Hoffman’s sign)?
Bowel and bladder dysfunction can originate from the cord but there are physical examination findings that go along with this dysfunction. If the problems stem from the cord injury, he does need surgery. Recovery is an unanswered question as even with cord decompression surgery, there is no guarantee that the cord will fully recover.
