BackgroundFoot and ankle injuries are among the most common lesions in traumatology, accounting for more than one in ten human fractures. The aim of this study was to investigate the demographic changes of patients with foot and ankle injuries, the temporal occurrence and the development over the years in an emergency department.Material And MethodsRetrospective study of patients treated for foot and ankle injuries in the emergency department from 2010-2017. Patients were identified by ICD codes and demographic changes, temporal occurrence and the development over the years were analyzed. Using quantile-quantile plots, continuous variables were tested for normal distribution and, if applicable, tested for significance using t‑tests or non-parametric Mann-Whitney U‑tests.ResultsA total of 6581 foot and ankle injuries were included in the analysis. The mean age of patients with a foot fracture was 39 ± 17.4 years and with an ankle fracture 47 ± 19.2 years (p < 0.001). Ligamentous ankle injuries occurred particularly in younger patients during the summer months. The age distribution of ankle fractures showed a peak incidence between 30-39 years of age for men and an increased occurrence in women over 50 years. In the age group between 65 and 75 years trimalleolar ankle fractures represented the second most common ankle fracture. Fractures of the foot most commonly affected patients aged 20-29 years, with a second peak incidence in women between the ages of 50 and 59 years.ConclusionLigamentous injuries of the ankle joint are common injuries in the emergency department and affect mainly younger patients. Ankle fractures showed a bimodal age distribution for women and especially bimalleolar and trimalleolar fractures were more common in women aged 65 years and older. Because of the increased prevalence of foot and ankle fractures in older women, further osteoporosis evaluation should be initiated in this patient population.© 2021. The Author(s).
