Which statement regarding chronic complications from fractures is accurate?

The statement about avascular necrosis accurately reflects a potential chronic complication that arises from fractures. Avascular necrosis occurs when there is a loss of blood supply to a bone, leading to the death of bone tissue. This condition can occur after a fracture, especially if the blood vessels supplying the bone are damaged or if the fracture disrupts the blood supply. Over time, without adequate blood flow, the bone may weaken and collapse, resulting in pain, loss of function, and the potential need for surgical intervention.

Considering the context, fat embolism syndrome typically presents acutely rather than as a chronic complication; it arises soon after a fracture, where fat globules enter the bloodstream and can lead to severe respiratory distress and other systemic issues. While fractures can contribute to a risk of osteoporosis, not all fractures lead to immediate osteoporosis, and the development of osteoporosis is influenced by various factors, including age, sex, and overall health. The statement about surgical hardware misleadingly suggests that it can prevent all complications; however, while it may aid in stabilization and proper healing, complications can still arise post-surgery. Therefore, the accuracy of the statement regarding avascular necrosis is reinforced by the understanding of how chronic complications develop in the context of fractures.
