Does osteogenesis imperfecta predispose infants to metaphyseal fractures? A systematic review.

OBJECTIVE

The notion that osteogenesis imperfecta (OI) predisposes children to metaphyseal fractures is controversial. This review aimed to ascertain the prevalence of metaphyseal fractures in children with OI less than 2 years of age.

MATERIALS AND

METHODS

Medline, CINAHL and Web of Science were searched for studies reporting metaphyseal fractures in children with OI less than 2 years of age. Articles not retrievable, not published in English, or where 'metaphyseal' fracture was not defined/illustrated, were excluded. Article quality was independently assessed using the Critical Appraisal Skills Programme and Case Reports tools.

RESULTS

Of 298 retrieved abstracts, 82 were duplicates: 216 articles were screened by title and abstract, excluding 186. Hand search of the remaining 30 articles identified two further articles. Only four articles were included: (1) 4/41 children with OI aged between 1 day and 3 years with 'metaphyseal' fractures; (2) a case series including a 16-month-old boy with three 'metaphyseal' fractures. Abuse concerns remained despite a type IV OI diagnosis (not genetically confirmed); (3) a 7-month-old girl with two 'corner' fractures suspected to have OI and to have been abused; and (4) a pair of siblings with 'metaphyseal' fractures and type XI OI (FKBP10 mutation).

CONCLUSIONS

There is limited evidence that OI predisposes infants and young children to metaphyseal fractures. The two diagnoses are not mutually exclusive and until further large studies are conducted, physical abuse should always be considered in infants and young children with metaphyseal fractures, even in those with confirmed OI.
