Broken leg

Your leg contains 4 bones (the femur, the patella, the tibia, and the fibula) and bends at the hip, the knee, and the ankle. After an accident, these bones may break (fracture) into 2 or more pieces. If a broken bone has been exposed to the outside, either by a cut over the fracture or by bone sticking out through the skin, it is called an open fracture. This is sometimes called a compound fracture.
