Osteosarcopenia, the concurrent decline of bone and muscle health, increases fall and fracture risks in older adults. Early detection and integrated management targeting both bone and muscle are crucial for preventing disability and improving outcomes.
Area of Science:
- Geriatric Medicine
- Metabolic Bone Disease
- Muscle Physiology
Background:
- Osteosarcopenia, a combination of osteoporosis and sarcopenia, is a prevalent geriatric syndrome.
- It is associated with increased risk of functional decline, falls, and fractures.
- Understanding the interplay of mechanical, metabolic, and hormonal factors in bone and muscle is vital due to global population aging.
Purpose of the Study:
- To provide a comprehensive review of osteosarcopenia.
- To summarize current evidence on its epidemiology, pathophysiology, diagnosis, and treatment.
Main Methods:
- Narrative review of existing literature.
- Inclusion of international consensus guidelines, population cohorts, interventional studies, and translational research.
Main Results:
- Osteosarcopenia results from low bone mineral density (BMD), muscle mass/strength loss, and metabolic changes (inflammation, lipotoxicity, altered tryptophan metabolism).
- Diagnosis combines BMD assessment (DXA) with sarcopenia evaluations (European/global consensus criteria).
- Management involves osteoporosis pharmacotherapy, resistance exercise, adequate protein intake, and potential supplementation (Vit D, Ca, creatine). Emerging strategies include hormonal modulators and anti-inflammatory agents.
Conclusions:
- Osteosarcopenia significantly elevates risks of falls, fractures, disability, and mortality.
- Comprehensive management targeting both bone and muscle decline is essential.
- Further research is needed to refine diagnostic criteria and evaluate combined interventions.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
