Understanding Fragility Fractures
For many older adults, hip and pelvis fractures are considered 'fragility fractures' because they result from minimal force, often a simple fall from standing height, due to underlying bone weakness. A combination of physiological changes, medical conditions, and external factors increase the risk of these injuries in seniors.
Key Physiological and Age-Related Factors
Osteoporosis
Osteoporosis, a condition causing bones to become thin and brittle, is a major contributor to hip and pelvis fractures in the elderly. As people age, bone breakdown often exceeds new bone formation. This is particularly true for women after menopause due to declining estrogen. Severe osteoporosis can lead to fractures from everyday movements.
Muscle Weakness and Impaired Balance
Age-related loss of muscle mass (sarcopenia) reduces skeletal support and impacts balance and gait. Neurological changes and conditions like Parkinson's or dementia further impair balance, increasing fall risk. Poor vision and hearing can also contribute to unsteadiness.
Lifestyle and Environmental Contributors
Environmental hazards in the home, such as loose rugs, clutter, and poor lighting, are common causes of falls leading to fractures. Lack of physical activity weakens bones and muscles. Poor nutrition, especially insufficient calcium and vitamin D, compromises bone health. Excessive alcohol and tobacco use also negatively impact bone density and increase fall risk.
Medical Conditions and Medications
Various chronic health conditions, including neurological disorders, thyroid issues, intestinal disorders, and heart conditions, can increase fracture risk by affecting bone strength or balance. Certain medications, such as long-term corticosteroids, sedatives, antidepressants, and diuretics, can weaken bones or impair balance. Regular medication review with a healthcare provider is essential.
Hip vs. Pelvis Fracture Risk Factors
While many risk factors overlap, the mechanism of injury can differ. Hip fractures often result from a direct fall onto the hip, typically in those over 65, and are strongly linked to osteoporosis.

How to Reduce the Risk of Fractures
Reducing fracture risk involves a multi-faceted approach. This includes prioritizing bone health through diet, supplements, and potential medical treatments; engaging in regular weight-bearing and balance exercises; assessing and modifying home environments to eliminate fall hazards; regularly reviewing medications with a doctor; and managing chronic health conditions.

Conclusion
Hip and pelvis fractures in the elderly are often the result of a complex interplay of factors, not just simple accidents. Underlying osteoporosis, coupled with increased fall risk due to muscle weakness, balance issues, sensory impairment, certain medications, and environmental hazards, significantly raises the likelihood of these injuries. Proactive strategies focusing on bone health, fall prevention, and managing health conditions are crucial for reducing risk and supporting healthy aging.
