National fractured his rib touring Thailand (7)
I believe the answer is:
british
'national' is the definition.
'fractured his rib touring thailand' is the wordplay.
'fractured' indicates an anagram.
'touring' indicates putting letters inside (touring can mean going round).
'thailand' becomes 't' (abbreviation on car registration plates).
'his'+'rib'='hisrib'
'hisrib' anagrammed gives 'briish'.
'briish' going around 't' is 'BRITISH'.
(Other definitions for british that I've seen before include "M [MUSEUM]" , "As people under a monarchy" , "Like these old pieces" , "Is birth necessary for nationality? (7)" , "Hits rib of this nationality" .)
