A two-year-old who fractured her arm after falling off a bed was given Calpol and sent home by a doctor at St George's Hospital.

The toddler spent three days with a swollen and painful arm after the doctor failed to diagnose the break.

Laura Ward, 27, and partner Jamie Pautsch, 32, waited for four hours with daughter Rebecca in accident and emergency only to be denied an x-ray - despite the girl being in so much pain she would not let the doctor touch her arm.

According to Rebecca's mother, the doctor told her it was "very unlikely" the toddler's arm had been broken after she fell between her cot and a bed on April 25, and sent her home with painkillers.

Ms Ward said: "I can't imagine what it was like for her. When adults break their arm, they're in agony. To have to go through that for three days without a plaster on it must have been awful. And she missed out on her brother's birthday party fun."

Ms Ward, who cares full-time for Mr Pautsch, who has multiple sclerosis, took Rebecca back to their Fayland Avenue flat near Tooting but when she continued to scream in pain they took her back to A&E on April 28.

After another battle to get an x-ray, two broken bones were found, but nurses refused to disclose the name of the junior doctor who made the mistake, claiming any complaint should be made against the department and not the individual.

Ms Ward said: "How is it that this doctor will not be investigated as a single individual for failure to do his job correctly?"

In an investigation released last week, chief executive David Astley apologised for the junior doctor's mistake and the failure to disclose his name, but added the doctor had been spoken to at length.

He also said radiation risk meant staff were wary of offering x-rays to children and added that no permanent damage had been done by the mistake.

A spokesman for St George's Healthcare NHS Trust added: "Firstly, we would like to repeat the apology, already given to Rebecca's family, for our failure to diagnose her fracture to her forearm on her first visit to A&E. An investigation has taken place into Rebecca's treatment and a detailed response has been sent to her family. This explains how we believe the mistake occurred.

But Ms Ward said: "I've completely lost faith in them. If a child has had a fall and they're too young to speak, they should be x-rayed."
