A so-called fragility fracture is a fracture condition in which the body or limb is fractured without significant external force or with only very slight external force. Fragility fractures, also known as osteoporotic fractures, are caused by the continuous loss of bone mass, loss of bone quality, and thinning of bone trabeculae, resulting in a decrease in the strength and fragility of the bone and an increase in its brittleness, so that fractures are likely to occur under minor external forces. The most common fractures are fragility fractures of the lumbar spine in the elderly, or fractures of the femoral neck, and some patients can even have fractures of the lumbar spine after coughing or after a bumpy bus ride. The most crucial thing to treat fragility fractures is to treat the cause of the disease and make sure to actively treat anti-osteoporosis and strengthen the bones so that the post-fracture can be avoided.
