What is an example of an extrinsic factor that can predispose a patient to a fracture?

In the context of factors that predispose a patient to a fracture, the amount of force applied is considered an extrinsic factor because it originates from external influences rather than internal conditions of the body. When evaluating the risk of fractures, the amount of force exerted on the bone plays a crucial role. This can include high-impact activities, accidents, or falls that increase the likelihood of the bone failing under such externally applied stress.

Conversely, the type of bone involved, age of the patient, and bone density are intrinsic factors related to the individual's physiological characteristics and vulnerabilities. The type of bone can influence its likelihood to fracture due to inherent structural differences, while age often correlates with changes in bone strength and overall health. Lastly, bone density directly relates to an individual's bone health, affecting the strength and resilience of the bones when stress is applied. These intrinsic factors are vital for understanding the overall risk for fractures but do not address the external forces that can lead to a fracture occurrence like the amount of force applied does.
