“…Several studies evaluated seasonality and the effect of weather conditions on the incidence of fractures across the countries and regions [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 31 , 32 , 33 , 34 , 35 ]. Practically all studies show an increased incidence of fractures in the elderly in the colder season, although monthly distribution may be different worldwide.…”

“…In the northern hemisphere, more fractures happen in December, January, and February. From the other side, in the southern hemisphere, more fractures occur in June, July, and August, even though these temperatures in winter months are higher in comparison with the northern hemisphere [ 35 ]. Many studies also show a direct relationship between fracture incidence and temperature, not only with season [ 22 , 32 ].…”

Aim: The incidence of fractures correlates with many independent and interrelated factors. The aim of the study was to examine trends in fracture incidence and to find possible reasons for changes. Materials and methods: A complete dataset of Polish population aged above 50 from the National Heath Fund—which is a single, state-owned payer for the health service procedures in Poland—covering the years between 2010 and 2015 was analyzed along with climate dataset. Results: The analysis indicated that there was a substantial and statistically significant decrease in the incidence of forearm and hip fractures (p = 0.007 and 0.007, respectively). On the other side, there was a statistically significant increase in incidence of humerus and lumbar fractures (p = 0.002, p < 0.001, respectively). The observed changes (especially decrease in forearm and hip fracture incidence) happened mostly in the cold season and were correlated to mean-temperature changes during the assessed time period. Conclusion: In the analysis based on the dataset obtained from fracture-related database collected in Poland in the years 2010–2015 in the population of patients over 50 years of age, we observed that the changes of fracture incidence during the observation period are associated with and may be dependent on the season (warmer versus colder) and on mean temperature increase during the observation period.

“…Isso ocorre devido à ausência de registros filiados a alguns serviços do sistema privado e do sistema complementar de saúde, geridos por empresas privadas de seguro de saúde e cooperativas de saúde. 11 Fica claro que este é um agravo com significativas implicações para a população situada nesta faixa etária, dentre elas o declínio da autonomia, da capacidade funcional e da qualidade de vida, constituindo-se complexo problema de saúde pública.…”

Objetivos: Descrever a incidência por gênero e região, letalidade e custos associados ao tratamento de fraturas do fêmur em idosos (≥ 60 anos) internados no Sistema Único de Saúde (SUS) do Brasil entre 2008 e 2018. Métodos: Estudo transversal, descritivo e retrospectivo das internações de idosos por fraturas do fêmur mediante análise dos dados secundários obtidos do Sistema de Informações Hospitalares do SUS entre 2008 e 2018; para cálculo dos coeficientes epidemiológicos, utilizamos informações dos censos demográficos (2000 e 2010) do Instituto Brasileiro de Geografia e Estatística. Resultados: 478.274 internações registradas no período, incidência 1,7 vezes maior no gênero feminino (média geral de 274,91/100.000 para mulheres e 161/100.000 para homens). A Região Sudeste obteve maior número absoluto de internações e a Região Sul, a maior incidência média geral anual (224,02/100.000). O custo médio anual foi de R$ 99.718.574,30. Conclusões: As fraturas do fêmur em idosos apresentaram alta incidência (478.274 mil internações; 224,02 casos/100.000 idosos), predomínio do gênero feminino (1,7F/1,0M), maior número absoluto de internações na Região Sudeste e maior incidência na Região Sul, letalidade elevada (aumento de 17,46%; média geral do coeficiente de 4,99%/ano) e custos vultuosos (aumento de 126,24%, média anual de gastos de R$ 99.718.574,30).

“…Traumatic femoral fractures most frequently occur in winter and occur indoors from 6 a.m.–12 p.m. for elderly adults. Reasons for this variation remain uncertain, and possible hypotheses have been shown as follows 30 , 31 , 32 , 33 , 34 : winters are darker and colder, 31 slipping on ice and snow, 32 and fractures occur in indoor environments. 33 , 34 Hypothermia among older people with undernutrition could lead to impairment of judgments and coordination and then lead to injury.…”

Objective Femoral fractures are a common cause of mortality and functional loss, mainly among older people, and there are few studies about the age in relation to traumatic femoral fractures. The aim of this study was to investigate the effect of age on the patterns of traumatic femoral fractures in patients presenting to our regional tertiary hospital. Methods The records of 2020 patients who presented with traumatic femoral fractures between 2013 and 2019 were retrospectively reviewed. The patients' clinical and radiographic records were reviewed. Univariate and multivariable logistic regression were used to identify independent risk factors for associated injuries and complications. Results The patients were divided into a child group (CH group, n = 342) aged under 18 years, a young adult group (YA group, n = 484) aged 18–60 years, and an older people group (OP group, n = 1194) aged 60 years and over. There were significant differences among the three groups in several indexes, such as sex ratio (χ2 = 301.699, p < 0.001), osteoporosis (χ2 = 375.463, p < 0.001), injury time of day (χ2 = 114.913, p < 0.001), injury cause (χ2 = 748.187, p < 0.001), injury location (χ2 = 490.153, p < 0.001), fracture side (χ2 = 57.000, p < 0.001), fracture site (χ2 = 806.650, p < 0.001), associated injuries (χ2 = 322.921, p < 0.001), coma after injury (χ2 = 147.814, p < 0.001), non‐surgery‐related complications (χ2 = 7.895, p = 0.019), and surgery‐related complications (χ2 = 82.186, p < 0.001). The YA group had a significantly higher percentage of patients with surgery‐related complications than the OP group. The OP group had a higher frequency of non‐surgery‐related complications than the YA group and CH group. The most common non‐surgery‐related complications were pneumonia (7.1%) in the OP group and deep venous thrombosis (6.4%) in the YA group. Multivariable logistic regression showed that young adults, high‐energy injury, outdoors, coma after injury, and fracture sites except for the proximal region were independent risk factors for associated injuries. Older age, male, and fracture site except for the proximal region were independent risk factors for complications. Conclusions Traumatic femoral fractures are mostly the result of low‐energy trauma and predominantly affect the proximal site of the femur among older people. A higher rate of shaft fractures, fractures occurring outdoors, and associated injuries were observed among young adults and children than among older people.
