Rib fractures in infants, particularly those situated posteriorly, are considered to be specific for non-accidental injury (NAI).Methods: Retrospective examination of radiographs of extremely low birth weight (ELBW) infants (⩽1000 g) with a gestation range of 22 of 33 weeks, cared for at a tertiary NICU, between 1998 and 2002, and who had survived ⩾4 weeks.Results: Five out of 72 (7%) infants studied had radiologically apparent rib fractures. None involved posterior rib shafts. All infants with rib fractures died on the NICU.Conclusions: The possibility of NAI should be considered in ex-ELBW infants found to have rib fractures.
