I have fractured my c2 axis vertebra. I have little or no problem turning my head, though I wear a cervical brace to prevent head movement and help the fractured bones rejoin. I am concerned that inadvertently I am disrupting this healing process by mybody position in sleep for example, or by bending my head or chest to lower them. Is there a written source that lists the dangerous, disruptive body positions (the ones likely to force the bones apart that have started to join and heal)? YYYY@YYYY
