A grandmother has been left with a shattered wrist and a long road to recovery after falling at her local Woolworths supermarket.

The slip happened less than a minute after a young girl sprayed cleaning product on the floor of a Woolies store in Melville, in Perth’s southern suburbs.

Dusanka Koljibabic, 69, had no idea what she was walking into until it was too late and she was on the floor.

“Very, very painful. I was in agony,” she told 7NEWS.

The grandmother suffered a shattered wrist, which required surgery to insert a metal plate.

“I was unable to shower, dress, or undress myself, cook, clean, do any gardening. Most definitely I wasn’t in the position to drive,” she said.

“I felt like my life has turned upside down in an instant.”

Five months on, Koljibabic says Woolworths continues to deny responsibility, but the retailer did offer her a single payment of $3000 dollars.

She has not accepted it, labelling it “insulting”.

Private health has covered some of the costs but Koljibabic needs ongoing rehabilitation..

She says it will take up to two years for her wrist to heal and claims she has been left at least $5000 out of pocket.

“I feel like as a customer I have been ignored and it’s through no fault of my own,” she said.

This case is all about timing. In 2012, the high court ruled supermarkets have a 15 to 20 minute window to identify and clean up hazards.

But Koljibabic says that policy is flawed.

“Whatever was on the floor was invisible to me and I don’t think even a staff member would have noticed it,” she said.

Personal injury lawyer Michelle Antunovich said: “For (the injury) to happen in such a short period is extremely uncommon.”

But there may be another avenue.

“I think there is certainly a claim against the guardian or the parent of the child that caused the damage,” Pragma Lawyers founding director Aaron McDonald said.
