SETH Muller walked out of Kingaroy Hospital thinking himself lucky to escape with minor injuries after a motorbike crash.
But three days later the 15-year-old Maryborough boy was struggling to breathe.
He was admitted to Maryborough Base Hospital, where tests revealed he had a broken back, collapsed lung and damaged kidney - and was told he should not have been walking.
An overnight stay and X-rays taken at Kingaroy Hospital had failed to identify the seriousness of Seth's injuries.
Seth's father Shane was shocked at the misdiagnosis. "Potentially this could have been absolutely horrible where he ended up in a wheelchair," Mr Muller said.
"Any degree of broken back should be treated seriously."
Seth suffered the injuries from a motorbike accident at Manar Park on Sunday when he landed on his back from a height of six metres.
"He was told (by Kingaroy Hospital staff) not to lie in bed for too long so he wouldn't seize up," Mr Muller said.
"When we got to the Maryborough Base Hospital he was put into a bed straight away and told he couldn't move until they got approval from the spinal unit in Brisbane."
Darling Downs Hospital and Health Service Cluster Operations Manager for South Burnett Peta Rutherford said a review had been opened into the incident.
"We take all complaints very seriously and in light of the information received from South Burnett Times both Kingaroy Hospital and DDHHS management have begun an immediate review of the case," she said.
