Prisoner wrong to bend (7)

I believe the answer is:

contort

'bend' is the definition.
(thesaurus)

'prisoner wrong' is the wordplay.
'prisoner' becomes 'con' (abbreviation for 'convict').
'wrong' becomes 'tort' (a civil wrong in law).
'con'+'tort'='CONTORT'

'to' acts as a link.

(Another definition for contort that I've seen is " Twist out of shape".)

I've seen this clue in The Mirror.
