Abstract

The aim of this study was to present an analysis of acetabular fractures during childhood as compared to those in adults. Within a multicenter register study, data of 3 time periods (1991-93, 1998-2000, 2004-2008) were pooled and analyzed for incidence, epidemiology, classification, outcome and treatment of acetabular fractures in children (< 15 years). One hundred fifty three children (2.1%) among 7360 patients with pelvic fractures were included in the study. Only 15 children sustained an acetabular fracture (9.8%). Simple fracture types according to Letournels' classification were more frequent in paediatric patients (p < 0.01), receiving less often operative treatment. Multiple injuries were present in 36% of children, the average Injury Severity Score (ISS) of all children was 17 points. Clinical results were good with an average Merle d'Aubigné score of 16.4 points and a Karnofsky performance of 90%. Fractures of the acetabulum in childhood remain a rare injury with distinct fracture characteristics, usually caused by high impact accidents
