Tibial fractures in very young children and child abuse

Three Part Question

In [very young children who present with tibial fractures] what are [the relative chances] of [accidental and non-accidental injury]?

Clinical Scenario

An 18 month old child attends the department with a limp. You question the mother of the child who explains that the child has fallen down three stairs at home. X-ray reveals a transverse tibial fracture. Further inquiry is unrewarding, and you wonder whether the prescence of the fracture alone is sufficient to support a diagnosis of non-accidental injury.

Comment(s)

The numbers of children with the target condition (tibial fracture) in the case series is small. However in the cases found there seems to be a clear link between tibial fractures in very young children (aged 18 months or less) and non-accidental injury.

Clinical Bottom Line

Very young children with tibial fractures should be closely assessed for non-accidental injury
