Damage dislocated arm (3)

I believe the answer is:

mar

'damage' is the definition.
(to mar is to spoil or damage)

'dislocated arm' is the wordplay.
'dislocated' indicates an anagram.
'arm' anagrammed gives 'MAR'.

(Other definitions for mar that I've seen before include "Disfigure" , "hurt" , "Cause harm" , "Blight" , "Ruin" .)

I've seen this clue in The Times.
