This is completely dependent on your local ortho.
What my ortho says and allows may be completely different from yours. Moreso, they may complain to your director. If it's bankers hours, call and ask. Get a rapport, even if they aren't on call. Just call the clinic you'll be sending people to and say "hey, what are your thoughts on this". You can do it on your off day if you don't want a major time suck.
