Recent trends in children's elbow dislocation with or without a concomitant fracture

BACKGROUND: The elbow is the joint that most usually dislocates in children. In contrast to the widely known recent increase in the incidence of upper-extremity fractures and their operative treatment in children, potential trends in elbow dislocation are not clear. In this study we aimed to clarify the recent epidemiology of childhood elbow dislocation, in particular the potential change in incidence and treatment. METHODS: A population-based study was performed to evaluate the annual incidence and the characteristics of injury, patients and treatment. All children < 16 years of age with an elbow dislocation in 1996–2014 in the Oulu University Hospital District, Finland, were included. Elbow dislocations with and without an associated fracture were included. The mean number of children in the population at risk was 85,600, according Statistics Finland. RESULTS: There were 104 patients with a mean age of 11.3 years (SD 2.6). The annual incidence was 6.4 (mean) per 100,000 children in 1996–2014 and no changing trend in incidence during the study period was found. Trampoline jumping was the most usual reason for the dislocations (N = 15, 14.4%). The majority (N = 73/104, 70.2%) were treated non-operatively by reduction and casting. There was no change in surgical treatment during the study time. CONCLUSION: In contrast to increasing incidence of upper-extremity fractures in children, there has not been a change in the incidence of elbow dislocation in children. There was no change in surgical treatment in 1996–2014.
