What is the difference between "apart", "except", "other than" and "besides"?

  • Fortunately, apart from a broken toe, she was not badly hurt after the car accident.
    -- while apart itself is acceptable, it is awkward in this particular example.
  • Fortunately, except (for) a broken toe, she was not badly hurt after the car accident.
    -- best option that conveys the meaning appropriately in the context.
  • Fortunately, other than a broken toe, she was not badly hurt after the car accident.
    -- fine; can be an alternative to except, which is the right word in this case.
  • Fortunately, besides a broken toe, she was not badly hurt after the car accident.
    -- inappropriate: avoid besides when showing an exception.
