Who breaks their hip? A decade of traumatic hip fracture data

Aims & objectives: Hip fractures lead to significant morbidity, mortality, and healthcare costs, particularly in elderly populations. Understanding the mechanisms underlying these fractures is crucial for developing targeted prevention strategies and counseling patients.

Methods: The National Electronic Injury Surveillance System (NEISS) was utilized to identify a cohort of 25,068 hip fractures from 2013 to 2022. The inclusion criteria mandated classification as a lower trunk fracture and explicit mention of hip fracture in the narrative. Patient age, race, sex, incident location, the time of year, and associated consumer products were compared using 95% confidence intervals and Chi-Squared tests of independence.

Results: A total of 25,068 hip fracture patients were included in this study. Females were more likely to fracture their hip (P < .001) representing 68.4% (95% CI 67.8%-69.0%) of all fractures. Patients were most likely to injure themselves at home (P < .001), accounting for 62.0 % (95% CI 61.4%-62.6%) of fractures. Falls to the floor represented 36.0 % (95% CI 35.4%-36.6%) of fractures, while fractures related to beds, stairs, and chairs emerged as other prevalent mechanisms at 11.2% (95% CI 10.8%-11.6%), 7.9% (95% CI 7.5%-8.2%), and 5.4% (95% CI 5.1%-5.7%), respectively. In the 50-60 age group, stairs present a prominent risk, representing 12.4% (95% CI 10.6%-14.5%) of fractures. Younger individuals suffered fractures most commonly due to high energy activities, such as falls from ladders, bicycles, and stairs (P < .001).

Conclusion: While falls remain the chief cause of hip fractures, many of these injuries stem from overlooked mechanisms. The heightened risk associated with falls from beds and chairs in the elderly, stair-related injuries in middle-aged individuals, and high-force modalities in younger people, highlights the necessity for tailored preventive measures. Providers should counsel their patients on risk reduction measures within the home, while Medicare and other insurers must work to expand coverage for these same measures.
