Background: In children with cerebral palsy (CP), fracture rates have been reported to be higher than in the general population but age-specific fracture rates have not been directly compared and the effect of comorbid epilepsy needs elucidation. This impairs decision-making regarding bone health interventions. Aim: We aimed to establish the age-specific fracture rates in children with CP with and without epilepsy in Denmark. Materials and Methods: Data from Danish registers were combined to establish cohorts of children with and without CP born in Denmark from 1997 to 2007. Fracture rates were calculated for 1997–2016. Results: We identified 1,451 children with CP and 787,159 without CP. Female/male fracture rates per 1,000 person-years were 23/27 with CP and 23/29 without CP. Male sex, epilepsy and anti-seizure medication, but not the diagnosis of CP or GMFCS-level, were associated with higher fracture rates. Relatively more lower extremity fractures occurred in non-ambulant children with CP. Interpretation/Conclusion: We found no increased fracture rates in children with CP when compared to peers; however, fracture locations suggested bone fragility in non-ambulant children. All children with epilepsy and on anti-seizure medication had increased fracture rates. We suggest bone health optimization in these groups.
