broke a hip/got broken her hip

  1. Just a couple of months ago, she fell and broke a hip.
  2. Just a couple of months ago, she fell and got broken her hip.
    Which of the two is more natural sentence to hear?

#2 is wrong.

#1 is closer, but normally one would say “she fell and broke her hip”.

Dozy,
“She got broken her hip.”
I think the above sentence is OK grammatically?
Then how could this sentence -
“Just a couple of months ago, she fell and got broken her hip.” is wrong?
Please explain with relevant grammar. Thanks.

Your sentence “She got broken her hip” is grammatically incorrect.

‘She got her hip broken’ would just about be acceptable grammatically, particularly if the meaning were that doctors deliberately broke her hip for some reason.

‘She broke her hip’ is the most natural correct form, as Dozy has already indicated.

  1. In the accident she got her hip broken.
  2. She got her hip broken in the accident.
    Are the above sentences are correct?

These both seem unnatural to me. You can say “She broke her hip in the accident”.

As I said, ‘she got her hip broken’ indicates that it was a deliberate act on her part to have it broken.
