What is the Origin of Skeletal Fragility?

The term combines "skeletal," referring to the bony framework of the body, with "fragility," derived from the Latin fragilitas (easily broken). This descriptive term reflects the clinical manifestation of underlying pathological processes, such as osteoporosis, which compromise the mechanical integrity of the bone.

What is the Mechanism of Skeletal Fragility?

Hormonal imbalance is a primary mechanistic driver, where deficiencies in sex steroids, like estrogen, or excesses in glucocorticoids accelerate the rate of bone resorption by osteoclasts relative to bone formation by osteoblasts. This imbalance leads to a net loss of bone mass and the disruption of the trabecular network, diminishing the bone's structural resilience. Other factors, including chronic inflammation and deficiencies in vitamin D and calcium, also impair the complex process of bone remodeling and mineralization.

Skeletal Fragility

Meaning

Skeletal fragility is a clinical condition characterized by compromised bone strength, leading to an increased susceptibility to fractures from minimal trauma or even spontaneously. This fragility is not solely defined by low bone mineral density (BMD), but also encompasses adverse changes in bone quality, including microarchitecture deterioration, altered bone turnover, and accumulated microdamage. It is a critical health concern, particularly in the aging population and in individuals with endocrine disorders like hypogonadism or hyperparathyroidism. Assessing fracture risk requires a comprehensive evaluation of both density and bone quality parameters.
