This is depressing. 

I have/had a young violin student who lost his index finger in a freak accident over the holiday. 

I know of people play different instruments in unconventional ways in order to accomodate for missing fingers, e.g., [Jean “Django” Reinhardt](https://en.wikipedia.org/wiki/Django_Reinhardt). 

He really loves the violin. Does anybody have any experience in this area? Can anybody point to some resources or is there, even better, a similar violin player?
