The good news is that restraints in motor vehicles have become optimized so people have a lesser incidence of upper body damage. Little attention has been paid to lower extremity injuries, however, in part because they do not cause mortality in general and they carry low injury scores. They do, though, cause a great deal of disability in those who suffer them. Not only is there a great psychological burden from lower extremity injuries but there is a longstanding possible disability. Other, unrelated injuries and factors like depression influence how the patient does long term.
A patient can sustain a foot injury from slamming the foot into the seat or footboard ahead of them. Foot injuries may or may not need to be casted but certainly they impair the ability of the patient to get around. It can mean days or weeks off the job until the individual can bear weight. Fortunately there are few long term disabilities from foot fractures.
