How are bone fractures classified?

Bone fractures are classified primarily as open or closed based on the condition of the skin over the fracture site. An open fracture, also known as a compound fracture, occurs when the break in the bone punctures the skin, creating a risk for infection and complications due to exposure to the external environment. On the other hand, a closed fracture, or simple fracture, occurs when the bone breaks but the skin remains intact, reducing the risk of infection.

This classification is crucial for medical professionals because it impacts treatment decisions, potential complications, and recovery plans. Open fractures often require more extensive treatment to prevent infection and promote healing, while closed fractures may be managed with less invasive approaches. The other options provided do not accurately capture the standard classifications used in medical practice for bone fractures.
