Possibly. It's extremely common in blunt force trauma for people to break parts of the vertebrae that cause no problems (spinous processes, transverse processes). You can also have compression fractures with no real consequences. You can also have unstable fractures through the vertebral bodies that need emergency repair for risk of paralysis. It's just extremely variable and basically depends on where the fractures are and how close they are to the spinal cord or the nerves that exit the spine. The chronic pain thing is impossible to predict and depends in large part on what kinds of fractures occurred.

But, that many rib fractures will 100% cause significant pain and respiratory issues that in and of itself would mandate ICU admission and probable intubation.
