Hi Andy,
Hopefully your daughter's talus wasn't badly dislocated or broken in too many places and she has healed up well. If it has, she still might want to slow down on any abuse she is putting her ankle through. It's no fun having ankle arthritis and affects your whole life. I have found a couple of groups dedicated to talus fractures. Check www.artificialankles.com and
http://health.groups.yahoo.com/group/Ankle_Joint_Replacement/

Best wishes,
Erick
