Osteosarcopenia and geriatric hip fractures: Current concepts

Area of Science:

• Gerontology
• Orthopedics
• Molecular Biology

Background:

• Global life expectancy is rising, leading to an increase in geriatric fractures.
• Osteosarcopenia, the co-occurrence of osteoporosis and sarcopenia, significantly impacts the elderly population.
• Hip fractures represent a major global health burden due to morbidity, mortality, and healthcare costs.

Purpose of the Study:

• To review the prevalence and correlation of osteosarcopenia with fragility fractures, particularly hip fractures.
• To explore the molecular underpinnings of the bone-muscle relationship in osteosarcopenia.
• To highlight the need for further investigation into osteosarcopenia's impact on patient management and outcomes.

Main Methods:

• Literature review on osteosarcopenia prevalence and its association with hip fractures.
• Examination of genomic and proteomic studies investigating the interplay between bone and muscle.
• Analysis of the endocrine roles of bone and muscle, including myokines and osteokines.

Main Results:

• Osteosarcopenia is linked to increased mortality and complications in hip fracture patients.
• Genomic and proteomic research is identifying potential biomarkers for osteosarcopenia.
• The endocrine functions of bone and muscle emphasize the complex interactions in osteosarcopenia.

Conclusions:

• Understanding osteosarcopenia is critical for managing elderly patients with hip fractures.
• Further research is needed to elucidate the molecular basis and clinical implications of osteosarcopenia.
• Optimizing management strategies requires a deeper understanding of myokines, osteokines, and their roles in bone-muscle health.
