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. He offers Online Physiotherapy Appointments for £45.Anatomy of the talus (reproduced courtesy of Dr Matt. ![]() We recommend a consultation with a medical professional such as James McCormack. Other forms of treatment include stabilisation surgery, but this is something that you should consult your orthopaedic consultant about. Isometric strengthening of the Posterior Tibialis and Peroneal Muscles is helpful to establish some early strength in the ankle, and these typically progress into isotonic strengthening exercises.Ī gait analysis can be required to identify any changes in biomechanics, and insoles can help provide additional support. In the early stages of rehabilitation, an ankle brace may be recommended for additional support.Įxercises for a Talus Fracture typically consist of gentle mobility and stretching of the calf muscle and ankle joint. If conservative treatment is recommended, a period of 6 weeks of non-weight bearing in a boot followed by 4-6 of gradually increased weight bearing in a boot is usually recommended before weaning out of the walker boot and beginning Physical Therapy.Īn initial assessment can identify muscular weaknesses and tightness that can be addressed with a thorough rehabilitation protocol. It is essential to consult your Physical Therapist and Orthopaedic consultant for an opinion on whether conservative or surgical treatment is most appropriate, depending on the fracture’s size and location. This type of fracture tends to be unstable and requires surgery, usually resulting from a high force injury.Ī lateral talus fracture (snowboarders fracture) occurs when your ankle is forced outward while a stress fracture to the Talus bone is a less common type of talus fracture, that usually occurs due to repetitive impact. The most common type of fracture to the Talus is to the neck, which attaches the body to the neck of the talus bone, and this can be a stable or unstable fracture.Īn unstable Talus Fracture occurs when a piece of bone is displaced from its attachment. It is one of the few bones in the body without any muscular attachments. Most of the talus bone is covered by cartilage, which protects the bone. In contrast, its connection to the Calcaneus allows the ankle joint to move from side to side. The Talus sits underneath the Tibia and the Fibula and above the Calcaneus allowing the ankle joint to plantarflex and dorsiflex. The Talus bone is vital in connecting the leg, ankle and foot. ![]()
