They have a higher risk for complications and infection and take a longer time to heal. In addition, open fractures expose the fracture site to the environment. Open fractures often involve much more damage to the surrounding muscles, tendons and ligaments. Open fracture: When broken bones break through the skin, they are called open or compound fractures.Unstable displaced fractures of the talus often require surgery to restore correct alignment and to give the best chance for the return to normal movement of the foot and ankle. Fractures that are highly displaced are more likely to be unstable. The amount of displacement relates to the amount of energy that caused the fracture. Displaced fracture: When a bone breaks and the pieces move out of their anatomic position, it is called a displaced fracture.In a minimally displaced fracture, the bones usually stay in place during healing, and surgery to fix the bones into position is not usually required. The broken ends of the bones line up almost correctly. Minimally displaced or stable fractures: This type of fracture is barely out of place.Talus fractures are often classified according to the severity of the displacement - how much the pieces of bone have moved out of their normal position. This area of the bone is called the “lateral process.” Fractures of the lateral process often occur when the ankle is forced out to the side and are commonly seen in snowboarders. Most commonly, the talus breaks in its mid-portion, called the “neck.” The neck is between the “body” of the talus, located under the tibia, and the “head,” located further down the foot.Īnother common site for talus fractures is along the outside of the bone where it juts out slightly. This cartilage allows the talus to move smoothly against its neighbor bones.įractures occur in all parts of the talus bone. It is largely covered by articular cartilage, the white slippery material that covers all joint surfaces. The talus is the main connector between the foot and leg, helping to transfer weight and pressure forces across the ankle joint. Together, the talus and calcaneus form the subtalar joint, which is important for walking, especially on uneven ground. The talus sits above the heel bone (calcaneus). The talus is the bone that makes up the lower part of the ankle joint (the tibia and fibula bones of the lower leg make up the upper part of the ankle joint). Severe fracture-dislocations of the talus sometimes require removal of the bone fragments and ankle fusion (arthrodesis) to achieve recovery. Talus fractures will often require surgery and long rehabilitation. For this reason, talar fractures are frequently associated with death of the bone, or ‘avascular necrosis’. Cartilage does not allow blood vessels to enter the bone, and this means that the talus has a vulnerable blood supply.
Most of the bone surfaces are covered by a protective smooth substance called cartilage. For this reason, you may require x-rays a few weeks apart to diagnose the fracture.įractures of the talus are often difficult to manage. In later weeks, the healing reaction of the bone can be more easily seen on X-Ray. Subtle fractures in the talus can be very difficult to see immediately after the fracture has occurred. Talar fractures will often require both X-Rays and CT scans to confirm the fracture and assess the degree of injury to the surrounding tissues. However, sometimes talus fractures occur with only small injuries when the bones are weak, as in osteoporosis. This can include falls and car accidents, as well as sports like snow-boarding. Usually a great deal of force is required to cause fractures or a dislocation of the talus. For this reason, many talus fractures require surgery. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. Because the talus is important for ankle movement, a fracture often results in significant loss of motion and function. Talus fracture often occurs during a high-energy event, such as a car collision or a high-velocity fall. Talus fracture is a break in the talus bone that forms the ankle.
