Objective: The social and economic cost of proximal femoral fractures is high, due the morbidity and mortality relating to the fracture itself, among other factors. Despite the importance of this issue, studies on this topic are still scarce in Brazil. This was a retrospective, observational and cross-sectional (ecological) study with the aims of outlining an epidemiological profile for proximal femoral fractures among the elderly and analyzing the causes of these fractures and the physical characteristics of patients admitted to a single university hospital in São Paulo. Methods: This was a study on medical records over a one-year period, with group comparisons using the chi-square test; p > 0.05 was considered significant. Results: Ninety-four individuals were evaluated: predominantly female (2:1); 81-85 years of age; body mass index within normal limits; white and Asian patients (p > 0.05). The vast majority of the fractures occurred through low-energy trauma and inside the patients’ homes (p > 0.05). After excluding the trauma resulting from high-energy events, over 39% occurred as the patients were moving from sitting to standing up or were using stairs, and approximately 40% occurred while they were standing still or walking. A greater number of cases corresponded to the cold seasons of the year (p > 0.05); Conclusion: Most injuries occurred inside the patients’ own homes and had low-energy causes. Thus, some accidents might be avoided through simple low-cost measures that guide the elderly regarding situations of risk, which would bring major quality-of-life benefits and significant decreases in morbidity, mortality and the socioeconomic costs of this increasingly frequent problem.
