An ankle fracture, also known as a broken ankle, is most commonly caused by the ankle twisting or rolling from tripping, falling, or an impact from an accident. Two joints are involved in ankle fractures, the ankle joint where the tibia, fibula and talus meet, and the syndesmosis joint, the joint between the tibia and fibula.
Treatment: Elevation and ice to reduce painful swelling and decrease the risk of damage to the surrounding tissue. A splint, worn for several days, may be placed to support the broken ankle and allow room for swelling. If the damaged ankle is not displaced, the splint may be applied immediately without moving the broken ankle. However, if the bones are displaced and/or the ankle joint is dislocated, a closed reduction is performed while the splint is placed. This treatment involves setting the tibia and/or fibula bones and ankle joint to improve the position and pain at the ankle. This treatment may require some type of anesthesia.The need for surgery will largely depend on the appearance of the ankle joint on the X-ray and the specific type of fracture. Badly displaced fractures and fractures of both the tibia and fibula commonly need surgery. During this type of procedure, the bone fragments are first repositioned into their normal alignment and are held together with special screws and metal plates attached to the outer surface of the bone.
