The ankle is made up of three bones: the fibula, tibia and talus. An ankle fracture occurs when one or more of the bones that make up the ankle breaks. Ankle fractures can be very common in children and according to OrthoInfo, ankle fractures in children are more likely to involve the fibula or tibia. Fractures at the ends of the fibula and tibia usually involve growth plates.
There are several ligaments in the ankle that hold the joint together, including ligaments that connect the tibia, fibula and talus to one another. Because of this, ankle injuries can be common due to sports. Twisting your foot or lower leg can cause ankle injuries, so it’s important to see a doctor and get an x-ray if you are injured. An x-ray can help determine if it is an ankle sprain or a serious ankle fracture.
