We prospectively analysed the epidemiology of acetabular fractures over a period of 16 years in order to identify changes in their incidence or other demographic features. Our study cohort comprised a consecutive series of 351 patients with acetabular fractures admitted to a single institution between January 1988 and December 2003. There was no significant change in the overall incidence of acetabular fractures, which remained at 3 patients/100 000/year. ⋯ The incidence of osteoarthritis noted during follow-up of operatively-treated fractures declined from 31% to 14%, reflecting improved results with increasing subspecialisation. Our findings suggest that there will be a continuing need for some orthopaedic surgeons to specialise in the management of these fractures. In addition, the reductions in the Injury Severity score and mortality may be associated with improved road and vehicle safety.
