Ice Bucket Challenge participant dislocates her jaw

THIS is the moment the ice bucket challenge went painfully wrong when a woman screamed so hard she dislocated her jaw.

A WOMAN has been hospitalised after screaming so hard during the Ice Bucket Challenge, that she dislocated her jaw.

Isabelle Roberts shouted so violently while freezing water was poured over her head that she damaged the structure of her face.

“The water was so cold so I screamed, but as I did it my jaw just started to stick,” she told The Mirror.

Unaware ... Isabelle Roberts moments before the accident

“I tried to close my mouth but it would not close, it was locked, and then I came to the realisation that something was up.

“Then my mum and sister came to the realisation and they started wetting themselves, but I had to be rushed to A & E (accident and emergency).”

The 20-year-old, from the UK, was taken to hospital to have her jaw repositioned after taking part in the viral craze on Tuesday.

The clip has become an internet sensation, having been shared thousands of times on Facebook and twitter.
