There are several types of bone fractures including compound fractures, impacted fractures, and greenstick fractures. A compound fracture is when broken bone fragments tear through the skin, posing a high risk of infection. An impacted fracture occurs when one broken bone end is wedged into the other, which often heals quickly. A greenstick fracture is a partial break more common in children where the bone bends without completely breaking. Treatment depends on the fracture type but may include realignment, immobilization, antibiotics, and exercise.
