London: A former rehab worker, who has filed a lawsuit against Lindsay Lohan, is undergoing surgery to repair an injury which she alleges was caused by the troubled star.
Dawn Holland, who now uses the name Dawn Bradley, is due to have an operation on her wrist on Thursday, reported Contactmusic.
Bradley has alleged that Lohan, 25, lashed out at her in December last year, when she checked into the Betty Ford clinic in California for treatment.
Bradley, who has recently filed a USD 1 million lawsuit against Lohan, claims that the `Mean Girls` star was violent towards her when she tried to administer a breathalyzer test.
She alleged that Lohan grabbed her wrist and "twisted and pulled it for 8-10 seconds".
Bradley`s lawyer said that ever since the reported incident, his client has been suffering from De Quervain syndrome, which causes pain, swelling and difficulty in gripping.
