E.g. Oliver, extremely emaciated and bent (7)

I believe the answer is:
twisted
'bent' is the definition.
('twist' can be a synonym of 'bend')
'e g oliver extremely emaciated' is the wordplay.
I cannot quite understand how this works, but
'e' is found in the answer.
'oliver' could be 'twist' (as in Oliver Twist) and 'twist' is found within the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for twisted that I've seen before include "Warped, perverted" , "Emotionally unbalanced" , "Turned round" , "like a pervert?" , "Coiled; distorted" .)
