Adult ankle fractures—an increasing problem?

Abstract

The epidemiology of ankle fractures is changing. Increasing longevity has resulted in the highest age-specific incidence of ankle fractures being in women between 75 and 84 years of age. the introduction of the AO classification has facilitated analysis of the commonest fracture types. This survey of 1, 500 ankle fractures, seen in a 3-year period in the Edinburgh Orthopaedic Trauma Unit, shows that the commonest ankle fractures are the B1.1 and A1.2 lateral malleolar fractures. Isolated malleolar fractures accounted for two thirds of the series, with bimalleolar fractures occurring in one fourth of the patients and trimalleolar fractures in the remaining 7%. Open fractures occurred in 2%.
