A former rehab worker who is suing Lindsay Lohan is undergoing surgery to repair an injury she alleges was sustained in an altercation with the actress last year (10).
The Mean Girls star was accused of lashing out at Dawn Holland - who now uses the name Dawn Bradley - in December (10) during her stint at the Betty Ford clinic in California.
Bradley, who has filed a $1 million (£625,000) lawsuit against Lohan, claims the actress was violent towards her when she tried to administer a breathalyzer test, grabbing her wrist and "twisting and pulling it for 8-10 seconds".
Bradley's lawyer tells Tmz.com that ever since the reported incident, his client has been suffering from De Quervain syndrome, which causes pain, swelling and difficulty gripping.
Bradley is due to have an operation on her wrist on Thursday (28Jul11).
