Hi,
Are you certain it isn't a neurological or musculature problem rather than the bones themselves?
Sorry to ask but it just occured to me looking at the way she moves - but I have zero experience of anything like this so figured I would ask.
If your tube feeding would it be possible to put the vitamin supplements we sprinkle onto crickets through it if you made the mixture slightly more liquid or thicker (say with AD )?
What mixture are you tube feeding them at the moment?
Just in case the answers help someone think of any more suggestions or something.
