ObjectivesAcute wrist trauma in children is one of the most frequent reasons for visiting the emergency department (ED). Radiographic imaging in children with wrist trauma is mostly performed routinely to confirm or rule out a fracture. The aim of this study was to determine how many radiographs of the wrist show a fracture in children following wrist trauma.MethodsA retrospective cohort study was performed in three Dutch hospitals from 2009-2010. Data were extracted from patient records and radiographic reports.ResultsOf the 1,223 children who presented at the ED after a wrist trauma, 51 % had a wrist fracture. The peak incidence of having a wrist fracture was at the age of 10 years; 65 % of the children younger than 10 years of age had a wrist fracture. Of all the patients without a wrist fracture, 74 % were older than 10 years of age.ConclusionAlmost half of the paediatric patients with a trauma of the wrist had normal radiographs. The development of a clinical decision rule to determine when a radiograph of the wrist is indicated following acute wrist trauma is needed. This could likely reduce the number of radiographs.Main Messages• Fifty-one percent of the children with wrist trauma have a wrist fracture. • Peak incidence of having a wrist fracture is at the age of 10 years. • Sixty-five percent of the children younger than 10 years of age had a wrist fracture. • Of all the patients without a wrist fracture, 74 % were older than 10 years of age. • The development of a clinical decision rule to reduce the number of radiographs is needed.
