Background: The incidence of completely displaced overriding distal metaphyseal radial fractures in children is unknown, and the optimal treatment is controversial.
Methods: All completely displaced distal metaphyseal radial fractures in patients <16 years old treated in our tertiary-level institution from 2014 to 2019 were identified with use of the Kids' Fracture Tool Helsinki. Etiology, fracture characteristics, management, and quality of treatment were assessed. A telephone interview with the guardian of the patient was performed for 100 (89%) of 112 patients at 1.5 to 7.2 years (median, 4.6 years) after the injury. Pain during the last month and forearm function were recorded. Treatment satisfaction was assessed with use of a 7-point Likert scale.
Results: A total of 113 completely displaced overriding distal metaphyseal radial fractures in 112 patients (81 of whom were residents of Helsinki) were treated during the 6-year-long study period. The mean annual incidence was 1.42 per 10,000 population. Most (73%) of these fractures occurred in children <11 years old, and most fractures were dorsally displaced and located nearly as far proximally from the distal radial physis as the maximum width of the distal metaphysis. Closed manipulation was attempted in two-thirds of cases in the emergency department, with a failure rate of 46%. Strong opioids were administered in 70 of 112 patients. None of the 26 patients whose fractures were immobilized in an overriding position had secondary interventions, pain, or functional disability. The mean satisfaction with treatment on the Likert scale was 6.2.
Conclusions: The annual incidence of overriding distal metaphyseal radial fractures patients <16 years old was shown to vary between 0.72 and 2.01 per 10,000 population. Opioids, local and general anesthesia, hospital admission, and secondary interventions can be avoided in prepubescent patients by casting these fractures in an overriding position while the patient is in the emergency department.
