The ankle joint is made up of the tibia, fibula, and talus (Figure 1). 35 40 years. Up to 50% incidence of associated injuries . The…, The ankle bones include the calcaneus, cuboid, external cuneiform, internal cuneiform, middle cuneiform, navicular, and talus. The aim of this study was to describe the normal anatomy of the lateral radiographic view of the ankle, focusing on the relative position of the fibula and tibial plafond. Trauma. Rapid axial load - very high energy . Fracture Anatomy The pilon fracture usually has an anterolateral (Chaput) fragment and a posterolateral (Volkmann) fragment, which usually remain attached to the distal fibula segment by the anterior and posterior tibiofibular ligaments. Tibial plateau fracture classifications are based on anteroposterior radiographs. tibia . Proximal limit of tibial pilon: 8-10 cm from the ankle articular surface. Structure and Function: Ankle Anatomy. Passes between 2 heads of tibialis posterior and interosseous membrane iom. Anatomy Tibial pilon = the distal end of the tibia including the articular surface. Epidemiology Pilon fractures account for 7%-10% of all tibia fractures. As is the case with tibial plateau fractures, these injuries occur close to the joint and must be treated with the cartilage surface of the ankle joint in mind. Healthline Media does not provide medical advice, diagnosis, or treatment. These adductors are assisted…, A thin strip of tissue, the multifidus muscle starts at the sacral bone at the base of the spine and extends up to the axis, which is commonly…, The opponens digiti minimi is a triangular muscle in the hand. These two bones connect the ankle to the knee and work together to stabilize the ankle and provide support to the muscles of the lower leg; however, the tibia carries a significant portion of the body weight. There are two bones in the shin area: the tibia and fibula, or calf bone. The distal portion of the tibia is known as the plafond, which, along with the medial and lateral malleoli, forms the mortise to articulate with the talar dome. The margin of the distal tibial joint surface and the attachments of the superficial fiber of the PITFL (sPITFL) and the deep fiber (dPITFL) were identified. Despite the numerous possibilities, certain reproducible elements can be identified. Articulates with the talus and fibula laterally via the fibula notch. Clinical features of pain swelling deformity and crepitus about the. Pilon fractures are caused by rotational or axial forces, mostly as a result of falls from a height or motor vehicle accidents. central non-articular intercondylar area. STUDY. Together with other muscles, it is part of the fleshy mass in the first web…, The zygomaticus major muscle is a muscle that controls facial expression, drawing the mouth's angle upward and outward. Tibial Plafond Issues . The plafond is concave in the anteroposterior plane and convex in the lateral plane. Plafond is French for roof (of ankle joint) Radiographic Examination of the Ankle Bones. ANATOMY The ankle mortise is made up of the articulations of the talus, the distal tibia, and the distal fibula. Tibial pilon fractures are severe injuries affecting the distal tibia, whereby the tibial plafond is injured by the talus punching up into it Patients will present following high-energy trauma, therefore concurrent injuries are common Check neurovascular status and for any evidence of an open fracture or compartment syndrome Management of soft tissues critical - restore length with external fixation - await swelling to dissipate . They are caused by high energy axial loads as the tibial plafond is injured by the talus punching up into it. Restoration of alignment / Joint surface imperative .
