Hip Fractures: Clinical, Biomaterial and Biomechanical Insights into a Common Health Challenge

Area of Science:

• Gerontology
• Biomedical Engineering
• Orthopedics

Background:

• Hip fractures pose significant public health challenges, especially for the elderly, leading to high morbidity and mortality.
• Current clinical tools like FRAX have limitations in accurately assessing individual fracture risk.
• Falls account for over 95% of hip fractures, highlighting the importance of prevention.

Purpose of the Study:

• To provide a comprehensive understanding of hip fractures from clinical, biomaterial, and biomechanical perspectives.
• To identify limitations in current hip fracture risk assessment tools.
• To explore integrated strategies for improved diagnosis, prevention, and treatment.

Main Methods:

• Review of clinical risk factors (age, bone density, falls).
• Analysis of bone composition (minerals, proteins, water) and its relation to bone strength.
• Exploration of biomechanical forces during falls and their impact on bone.
• Discussion of passive and proactive preventive strategies.

Main Results:

• Current clinical tools have limitations; bone composition may offer more reliable risk assessment.
• Emerging imaging technologies for bone composition assessment face challenges.
• Fall impact forces can exceed physiological loads, causing fractures.
• Proactive preventive strategies are more effective long-term than passive measures.

Conclusions:

• An interdisciplinary approach integrating clinical, biomaterial, and biomechanical factors is crucial.
• Improved diagnostic accuracy and prevention strategies are needed to advance public health outcomes in aging populations.
• Focusing on fall prevention and bone health is essential for reducing hip fracture incidence.
