A court has heard that a baby allegedly abused by his father suffered injuries consistent with being hit multiple times and burned with a hot bottle.

A baby boy allegedly abused by his father was likely hit multiple times with a blunt object, a Queensland court has heard.

The 11-month-old child was found burned, bruised and with two broken bones after spending the weekend at his father’s house southeast of Brisbane last June.

The 25-year-old man denies abusing his son and has pleaded not guilty to assault and child cruelty in the District Court in Brisbane.

Two doctors told the second day of the man’s trial that the injuries were unlikely to have been accidental.

Pediatric radiologist Dr Michael Guandalini said the child had suffered a broken rib that could have been caused by someone holding him around the rib cage and squeezing.

“To cause a break in that location, it would require a significant amount of force,” he said.

A broken bone in the baby’s lower leg could have been caused by the child having its limb twisted with significant force, he told the court.

Pediatrician Dr Matthew Wakeley said a large burn next to the baby’s mouth was consistent with a bottle carrying a hot liquid being applied to the area.

A missing tooth and several bruises found on the boy’s body – including a 7cm bruise on his chest – were consistent with forceful blows from a fist or other blunt object.

Dr Wakeley said the child, who was in hospital for two weeks, would have suffered significant pain.

“We were very concerned about the number and type of the different injuries,” he said.

Under cross examination Dr Wakeley agreed the child’s liver had shown elevated enzymes but ruled out liver disease as a cause of the bruises.

No other tests had shown abnormal liver functioning, he said.

The trial continues.
