Fractured right radial head on saturday. Er doc said it was non surgical and put it in a splint. Can't afford an ortho visit (no $ no ins). What to do?

Ask for help. While health insurance is expensive, you should not compromise your health. The hospital where you were seen may have assistance programs or you may qualify for government insurance. They should have counselors who can help you. If you don't qualify, you need to take care of your health and that might mean having to borrow money or make payment arrangements with the orthopedist. Talk to them.
