A case of traumatic osteomyelitis in a victim of child abuse.

A premature black female infant born at 31 weeks gestation with history of 4 weeks in the newborn intensive care unit was discharged healthy to the care of her mother and was lost to follow-up. At age 4 months the infant was found dead in bed. There was no history of trauma and no external injuries were noted. There was no attempt at resuscitation. Coroner's autopsy showed acute bronchopneumonia, 3 partially healed skull fractures, a chronic subdural hematoma, chronic intracerebral hemorrhage, retinal hemorrhages, multiple healing rib fractures, a fractured fibula, and a partially healed fracture of the distal right radius. The fracture of the right radius showed a medullary abscess of the bone surrounded by scar tissue and containing pus and granulation tissue. We believe this inflicted fracture became secondarily infected by a hematogenous route. The final diagnosis of the cause of death was pneumonia secondary to multiple blunt force trauma, and the manner of death was diagnosed as homicidal. This is believed to be the first reported case of osteomyelitis in a context of child abuse.
