Monteggia fracture aka night-stick fracture. Why night-stick # ? becos if u happen to sneak in the middle of the night to meet ur gf and her awake and alert father confronts u with a stick directed to ur head and u bring ur forearms up to cover ur head, then the ulna will take the brunt of the stick and b fractured.....no kidding :hhh: Note : I am not talking from experience.
