Abstract
Background and Objectives: Ankle fractures represent one of the most common injuries to the lower limb, particularly impacting women and the elderly. The coronavirus disease 2019 (COVID-19) pandemic greatly disrupted both the incidence of these fractures and their treatment patterns globally. This retrospective epidemiological study analyzed 1010 cases of ankle fractures treated at the Orthopedics Department of Policlinico University Hospital in Catania from 2018 to 2023. The study aimed to evaluate trends in incidence, patient demographics, fracture types, treatment modalities, and hospital stay across the pre-COVID-19, COVID-19, and post-COVID-19 periods. Materials and Methods: A retrospective observational study was conducted including all patients diagnosed with ankle fractures from 1 January 2018 to 31 December 2023. Data were collected from hospital medical records using ICD-9-CM codes and radiographic classification systems (Danis-Weber, Lauge-Hansen, and AO/OTA). Variables analyzed included demographics, fracture type and side, treatment modality, and hospitalization details. Statistical analyses were performed using t-tests, chi-square tests, and linear regression, with significance set at p < 0.05. Results: In 2020, there was a 31.7% decrease in fracture incidence. Although overall fracture rates rebounded after COVID-19, they did not reach pre-pandemic levels. During the pandemic, trimalleolar fractures increased significantly, occurring more frequently in older women, likely due to bone fragility. The rate of surgical treatments rose during and after the pandemic, with a distinct shift from ORIF to external fixation. Hospital stays were longer, especially for patients with cardiovascular risk factors. Conclusions: The pandemic significantly altered the epidemiology, treatment strategies, and outcomes of ankle fractures. These findings highlight the necessity for adaptable care models and preventive strategies, particularly for vulnerable populations such as older women.
