Epidemiology of Femur Fractures in Adult Patients: The Role of Age, Sex, and Osteoporosis in a Cross-Sectional Study from Malang, Indonesia

By Suryana BPP, Pratama MZ, Putra DP

Background: Femur fractures are a serious health issue across all age groups, leading to disability and even mortality, particularly in older adults with osteoporosis. This study aimed to examine the epidemiology of proximal femur fractures and their relationship with age, sex, and osteoporotic features in Malang, East Java, Indonesia. However, such data are limited in Indonesia, especially at the regional level. Methods: This observational study was conducted at Saiful Anwar General Hospital from January 2021 to December 2023. A total of 367 patients were included in this study. Data were analyzed using chi-square tests (significant if p < 0.05). Results: Most fractures occurred in females (57.8%) and patients aged 71-80 years (26.2%). Slips and falls were the predominant causes of fractures (81.5%), followed by traffic accidents (18%). Most fractures were in the intertrochanteric region (47.1%), and 67.3% of the patients exhibited osteoporotic features. Significant relationships were found between age, sex, osteoporotic features, and both Mechanism of Injury (p < 0.001) and fracture location (p < 0.001). Conclusion: We found that femur fractures are strongly associated with age, sex, and osteoporosis. Older adults and females are at higher risk of fractures from falls, particularly in the intertrochanteric region. Preventive measures focusing on osteoporosis management and fall prevention are essential for reducing the incidence of femur fractures in this population.
