So far no Danish study has aimed to describe the development of incidence rates of paediatric fractures. Purpose / Aim of Study: To describe the long-time development in the inci- dence rates of paediatric fractures and to describe the frequency of the most common fractures. Materials and Methods: A retrospective register study of all paediatric bone fractures 0-15 years inhabited in the Odense Municipality and treated at Odense University Hospital 1980-2014. Data was extracted from the patient registration system and stratified by gender and age groups. Findings / Results: The study included 32,927 children aged 0-15 with frac- tures. Overall 58 % were boys and the median age was 11 years for both boys and girls. The peak age in males was 13 years throughout the study period, whereas a tendency of declining peak age was found in girls from 11 years of age in 1980 to 10 years of age in 2014. The incidence rate was 330 (95% CI: 304-358) per 100,000 patient-years for boys and 258 (95% CI:226-274) per 100,000 patient-years for girls. The highest incidence rate was found in the age group 12-15 years and the lowest in the age group 0-1 years in both boys and girls. The incidence rate increased steadily until the age of 13 years for boys and 11 years for girls. Hereafter the incidence rate decreased rapidly. The overall incidence rate declined 23.4 % in in the study period as boys and girls contributed equally to the decline. The most common fracture was that of the distal radius/forearm with 28.5 %. Conclusions: The present study does support the findings in previous studies. Our study showed a significant decline in the incidence rate of pediatric frac- tures in a 35 years period 1980-2014. Boys and girls contributed equally to the decline. 125.
