To answer the OP more clearly.
Leg bones work just fine. You should boil them, clean them out and let them dry. I would suggest a full length stick tang with a butt cap that is fastened to the tang and the bone filled with 2 part epoxy.
That is the method I used on the knife in the pics I posted above with a 11 year old leg bone for the handle.
Go for it.
