Final answer:
Long bone fractures can have several complications, including the release of fat globules that can block the capillary beds in the lungs. Other complications include mobility impairment, increased risk of blood clots and pneumonia, and higher likelihood of fractures in elderly individuals with weakened bones.
Step-by-step explanation:
When a long bone is fractured, there can be several complications that arise. One common complication is the release of fat globules into the bloodstream when the diaphysis of the femur is fractured. These fat globules can block the capillary beds in the lungs, leading to respiratory distress and potentially death if not treated quickly.
In addition, fractures of long bones such as the femur can impair mobility and may require surgery. Other complications of fractures include deep vein thrombosis, pulmonary embolism, and pneumonia due to immobilization. Fractures can also be more common in elderly individuals with weakened bones due to conditions like osteoporosis.
