5 This results in a lateral shift of the talar head, an upward shift of the lateral process of the talus on the posterior articular surface of the calcaneum and loss of congruity of the posterior articulation. The suggested mechanism is thought to be a consequence of forced dorsiflexion and inversion of a fixed pronated foot. Lateral process fractures are usually a result of high-energy injuries. 2- 4 This article aims to provide an overview of fractures of the lateral and posterior processes of the talus. 1 Factors that can affect the outcomes of these fractures are the extent of initial articular damage, the accuracy of the reduction and the subtalar joint stability. Delayed diagnosis and treatment can potentially lead to poor outcomes, resulting in long-term pain, disability, nonunion and degenerative changes. Their management depends on the type, size of the fragment, degree of displacement, subtalar joint involvement and the articular surface lesion. They are uncommon and frequently missed due to difficulty in visualizing them on plain radiographs and low level of suspicion. Fractures of the lateral and posterior processes are considered to be peripheral talar fractures. Skalski, : ).įractures of the talus are uncommon and they comprise 3.4% of foot and ankle fractures and 0.32% of all fractures in the human body. If you get good treatment and you follow your doctor’s advice during your recovery, you should eventually be able to enjoy the activities you once did prior to your injury.Anatomy of the talus (reproduced courtesy of Dr Matt. In many cases, though, blood flow resumes and the prognosis is a healthy one. In serious cases, when the blood vessels don’t recover, bone cells die and the ankle can collapse. The bone can become damaged when healthy blood flow to the broken bone is disrupted by injury. The other complication is avascular necrosis. If the arthritis is serious, you may need surgery to treat the cartilage and stabilize the ankle. In many cases, it’s minor and more of a nuisance than a problem that interferes with your daily activities. Damage to the cartilage in the ankle joint can develop into arthritis down the road, even if the talus fracture heals properly. If your talus fracture is treated promptly and effectively, there should be no long-term complications. The bone may also be drilled into to promote blood vessel growth and healing of the chipped bone. If it doesn’t heal properly, you may need surgery to have the chip removed. If the chip is discovered early, you may be able to have a cast around your ankle for several weeks while the bone heals. A small piece of bone can become separated from the rest of the talus. In some cases, changing an activity, such running on a harder surface or with more incline than you’re used to, can trigger a stress fracture. It usually happens as a result of repetitive actions putting stress on a bone or joint.
TALUS FRACTURE TREATMENT CRACK
A stress fracture is a small crack or a bruise of the bone. The talus is one of several bones commonly subject to a stress fracture in the foot. In addition to those fractures, you may also break your talus in other ways. The risk of infection is higher with these injuries. Pins or screws may be needed, as well as treatment of the damaged muscles and other tissue. Surgery to treat an open talus fracture often involves much more than lining up the broken pieces of bone. Muscles, tendons, ligaments, and nerves may also be injured. If a piece of broken bone pierces the skin, it’s considered an open or compound fracture. This is the most severe type of fracture. Surgery is typically required to get the broken parts of the talus to line up correctly again. Highly displaced fractures are considered to be unstable. Displaced (unstable) fractureĪny time a bone moves out of its normal position, it’s called a displaced fracture. The break can usually heal without surgery. The fractured ends of the bone are still basically lined up properly. In this type of break, the bone is moved only slightly out of place. There are three main classifications: Minimally displaced (stable) fracture Talus fractures are usually classified based on the severity of the injury and how much the bone is moved from its normal position.
