Which condition results from a lack of bone mass and can lead to fractures?

Osteoporosis is a condition characterized by a decrease in bone mass and density, which makes bones fragile and more susceptible to fractures. This occurs when the formation of new bone doesn't keep up with the loss of old bone, leading to a significant reduction in bone strength. As a result, individuals with osteoporosis are at an increased risk for fractures, even from minor falls or injuries that might not affect individuals with healthy bone density.

The condition is especially common in older adults, particularly postmenopausal women, due to hormonal changes that can affect bone density. It’s essential for individuals to be aware of this condition, as it often progresses without symptoms until a fracture occurs.

Other options involve different physiological issues. Arthritis involves inflammation of the joints but does not primarily affect bone mass. Muscular dystrophy is a genetic disorder leading to muscle weakening, and joint inflammation can occur with various forms of arthritis but again is not directly related to bone density or mass.
