The appropriate treatment for osteochondral injury of the tibial plafond is unclear. The ankle is actually less susceptible to arthritis than the hip or knee. An angle of less than 84 degrees is regarded as talipes varus, and an angle of more than 94 degrees is regarded as talipes valgus. Tested Concept, (OBQ05.157) View Media Gallery Tibial plateau fractures. Contact us. The ankle joint has a rich arterial supply. However, coronal and sagittal images clearly show that the lesion originates from the tibial plafond. Each fracture was categorized according to the location of the major fracture line on the computed tomographic image at the level of the tibial plafond. Vascular insult is an unlikely cause of os-teochondral injury in the tibial plafond. New Hall Hospital, Salisbury, Wiltshire, UK, SP5 4EY. Page author: A similar change from smooth to wavy physeal contour with age is evident in other long bones, such as the femur (see , Figs 4a , , 4c , , 11 ). Go to the full DICOM version. Plafond fractures are infrequent injuries, accounting for 7-10% of all tibial fractures. Introduction: Osteochondral lesions of the tibial plafond account for approximately 2.6% of osteochondral lesions in the ankle. A 32-year-old man sustains a pilon fracture which is treated initially with a spanning external fixator, as shown in figure A. B. CT coronal reconstruction. Tested Concept, Immediate definitive fixation of the tibia, and nonoperative treatment of the fibula, Immediate ankle-spanning external fixation device with consideration of immediate fixation of the fibula, followed by delayed reconstruction of the tibia, Placement of a temporary splint, elevation, and definitive fixation 1 week from injury, Immediate definitive fixation of the tibia and fibula, Immediate placement of a spanning Ilizarov fixator with limited internal fixation of the distal tibia and fibula, (OBQ11.103) 1 Patients frequently have pain, impaired ankle function, and decreased general health status. When Tibial Plateau Fractures Are A Pain The tibial plateau is an important weight -bearing part of the body that connects the thighbone (femur) to the shinbone via ligaments. Technique guide are not considered high yield topics for orthopaedic standardized exams including the ABOS, EBOT and RC. X-rays of the leg, ankle, and foot are commonly done to evaluate a pilon fracture. These are considered to represent 1-10% of all lower limb fractures 6. A pilon fracture (also called a tibial plafond fracture) is a comminuted fracture of the distal tibia involving the ankle joint. All patients had a CT scan prior to definitive fixation. The patient's BMI is 52 and he smokes 2 packs of cigarettes per day; a clinical photograph of the limb is shown in Figure B. Each fracture was categorized according to the location of the major fracture line on the computed tomographic image at the level of the tibial plafond. The necrotic fragment usually becomes revascularised and reattaches to the surrounding bone. View Tools Recall Comm. A focal superiorly oriented notch at the medial aspect of the distal tibial physis… Fig. What is the most appropriate next step in treatment? SBCs occur in the subchondral bone, which is the layer of bone right under cartilage. Rüedi and Allgöwer (1979)—The system of Rüedi and Allgöwer is perhaps the most widely used classification of tibial plafond fractures reported in the literature. Tested Concept, Closed reduction and splinting followed by delayed casting, Immediate open reduction internal fixation, Closed reduction and splinting, CT scan, and immediate open reduction internal fixation, Closed reduction and splinting, CT scan, external fixation, delayed open reduction internal fixation, Closed reduction and splinting, external fixation, CT scan, delayed open reduction internal fixation, (OBQ12.199) Tibial plafond Background Posterior pilon, which has drawn attention over re-cent years, is considered as a variant of posterior mal-leolar fracture [1–15]. Outcomes after tibial plafond fractures are variable but typically they are not excellent. Computerized tomography (CT) scans. The treatment of tibial plafond fractures is challenging to foot and ankle surgeons. 1. Pilon fractures, or fractures of the tibial plafond, range from low- to high-energy axial-loading injuries. All courses are CME/CPD accredited in accordance with the CPD scheme of the Royal College of Radiologists - London - UK. Although the ligaments are needed to give the ankle its full stability, the bony congruity of the mortise and the talus is a necessary component as well forming the … He is initially treated with a spanning external fixator followed by definitive open reduction internal fixation of the tibia and fibula. Our e-learning platform contains high resolution images and a certified CME of the Internal fixation of distal tibial Pilon fracture using Stryker AxSOS 3Ti plate surgical procedure. 1,6,7,9,10,19 This study is the first report of the tibial plafond attachment of the PITFL focused on the positional relationship with the articular surface. 1. (Read bio). Although the ligaments are needed to give the ankle its full stability, the bony congruity of the mortise and the talus is a necessary component as well forming the … (b) Sagittal T1-weighted MR image (450/14) of the ankle in 14-year-old girl shows a more undulating distal tibial physis and zone of provisional calcification (arrow), typical for older children. It is also known as Pilon fracture and explosion fracture. Fracture anatomy was drawn out using the tibial plateau grid described above. What is the recommended initial treatment? Quantitative Analysis of Talar Dome Morphology. Results: Of 751 cases of adult ankle fracture fixation identified, 50 patients had perfect lateral images of the contralateral side. • A true lateral fluoroscopic image is obtained when the posterior and distal femoral condyles are collinear with one another, and the medial and lateral aspects of the tibial plateau are aligned – a bigger bump can be used if the nonoperative leg remains in view, and the leg adducted or abducted to improve the lateral fluoroscopic image. (b, c) Sagittal fluid-sensitive MR images are showing a superior talar neck (arrows) and anterior tibial osteophytes (dashed arrows) in a male with anterior ankle impingement symptoms. 1c) were measured using the axial images. without specific Copyright © 2020 Lineage Medical, Inc. All rights reserved. CT image through the tibial plateau shows a fracture of the posterior aspect of the lateral tibial plateau, which is the source of the lipohemarthrosis. the tibial plafond has low signal intensity on T1-weighted images and high signal inten- sity on T2-weighted images, with adjacent bone marrow edema (Figs. There is a comminuted distal tibial fracture extending into the tibial plafond, representing a Pilon fracture. 1-5 Most studies that report outcomes after these fractures have assessed patients at a single point in time and report an average length of follow up. However, conclusions regarding the superior choice remain controversial. Tested Concept, Brake travel time is significantly increased until 6 weeks after patient begins weight bearing, Return of normal brake travel time takes longer after long bone fracture compared to articular fractures, Normal brake travel time correlates with improved short musculoskeletal functional assessment scores, Brake travel time is significantly reduced until 8 weeks after patient begins weight bearing, Brake travel time returns to normal when weight bearing begins, (OBQ08.182) Apparent irregularity (arrow) along lateral fibular metaphysis on frontal view (a) has well-corticated margins (arrowheads) on oblique view (b). Tested Concept, open reduction internal fixation of the fibula only, open reduction internal fixation of the tibia and fibula, removal of external fixator and conversion to a walking cast, (OBQ04.216) Very interesting case of a typical Osteochondritis Dissecans in the posterior tibial plafond. C. CT three-dimensional reconstruction. Which of the following treatment regimens has been shown to decrease wound complications in the definitive management of these injuries? A 33-year-old male sustains the injury shown in Figure A. Excision of the diseased osteochondral defect. Arthritis of the ankle - wear of the ankle - typically affects younger patients. Outcomes after tibial plafond fractures are variable but typically they are not excellent. A focal superiorly oriented notch at the medial aspect of the distal tibial physis… A pilon fracture (also called a tibial plafond fracture) is a comminuted fracture of the distal tibia involving the ankle joint. He was treated initially with external fixation for 11 days before his soft-tissues would permit definitive open internal fixation. Members receive the 'Picture of the week', new operative techniques and can submit their problem cases for an expert opinion. There are also associated fractures of the talar dome and tip of the lateral malleolus. Approach to Osteochondral Lesions of the Tibial Plafond Fig. A 35-year-old male laborer falls off a ladder and sustains the injury shown in Figures A and B. Dr Graham Lloyd-Jones BA MBBS MRCP FRCR - Consultant Radiologist - If both the tibia and fibula are fractured, which is usually the case in the severe cases, it really doesn't matter where the fibula is fractured (mid-shaft, lower shaft, or distally/lateral malleolus), the fixation of the fibula at any level would be included in the code 27828.So the answer to your question is no. Guide wire tip should rest just above the tibial plafond, with bent area turned posteriorly. Three of The optimal approach side can be determined according to: Size of the anterolateral fragment: when it is large, and its medial fracture plane is at or near the medial malleolus, an anteromedial approach is recommended. In 11 patients (22%), the posterior border of the fibula intersected precisely at the posterior edge of the tibial plafond. In together with the two signs, posterior pilon fracture is in highly suspicion. A 55-year-old female presents to the emergency room after falling off her balcony. Home; Gallery; Tibial plafond; Upload & Save . After removing the external fixator and plating the fibula, what would be next step in the operative plan for reduction and fixation of this injury? All medial malleolar osteotomies showed complete union at 3 months postoperatively. Login or register to get started. Tibial plateau fractures. Tibial Plafond Fracture External Fixation Orthobullets Team Trauma ... Coronal and sagittal CT scan images are shown in Figures D and E. What is the MOST appropriate next step in management in addition to operative irrigation and debridement? There is a comminuted distal tibial fracture extending into the tibial plafond, representing a Pilon fracture. She sustained the isolated, closed injury shown in Figures A and B. If the articular anatomy of the tibial plafond is in reasonable condition, then the focus of the reconstruction can be on addressing only the metaphyseal nonunion. Most tibial pilon fractures are best approached anteriorly. X-rays provide images of dense structures, such as bone. If a defor-mity above the ankle is suspected, it is generally accepted Open DICOM files . Very interesting case of a typical Osteochondritis Dissecans in the posterior tibial plafond. There is no soft tissue swelling The distal tibial physis is also often irregular. A 46-year-old male falls 15 feet from a ladder while working. Specific Classifications Systems. The preoperative Mikulicz line was calculated by drawing a line between the center of the femoral head and the center of the tibial plafond. In past anatomic reports of the tibial plafond attachment of the PITFL, the length, the width, and the size of the attachment of PITFL were varied. The cross angle (α, Fig. ©Radiology Masterclass 2007 - now=new Date In my experience these lesions have a good healing potential without developing a loose body. Get an accredited certificate of achievement by completing one of our online course completion assessments. Using the PACS, the corrected Mikulicz line was drawn by connecting the center of the femoral head and the 62.5% point of the plateau on the whole-leg standing X-ray (green line in Figure 1 ). An x-ray can show if there is an injury to your bones or if the joints in your ankle are out of place. He has a 2 cm laceration over the medial ankle with exposed bone and a normal neurovascular exam. There is no soft tissue swelling The distal tibial physis is also often irregular. The tibial plafond, lateral malleolus, and medial malleolus form a mortise, a socket in which the talus sits (Figure 2). What would be the most appropriate sequence of treatment steps for definitive management of this injury? Follow Radiology Masterclass on Facebook or sign up to our email newsletter to get the latest news and offers. Preoperative radiographs of case 3. a-b The Arrow Head showing the “double contour” sign on AP view indicates the existence of PM fragment. “Pilon,” the French word for pestle, was first used by Etienne Destot in 1911 as an analogy for the mechanical function of the distal tibia on the talus. What is the most appropriate definitive treatment? What is the most appropriate next step in management? He sustained an injury to his right leg as seen in Figures A and B. Most fractures are secondary to high-energy trauma that result in significant bone and soft tissue damage. Varus or valgus deformity, if suspected, can be measured with the frontal tibiotalar surface angle (TTS), formed by the mid-longitudinal tibial axis (such as through a line bisecting the tibia at 8 and 13 cm above the tibial plafond) and the talar surface. Footnote: (a) An illustration in the mid-sagittal plane is demonstrating the involved anterior joint capsule (circle) with associated osteophytes from the anterior tibial plafond and anterior talar neck. Rüedi and Allgöwer (1979)—The system of Rüedi and Allgöwer is perhaps the most widely used classification of tibial plafond fractures reported in the literature. It involves the articular surface of the ankle joint. A 'pilon' fracture is any fracture of the distal tibia which involves the articular surface of the tibia - also known as the 'tibial plafond' Terms and Conditions There are also associated fractures of the talar dome and tip of the lateral malleolus. 15.1 Fibular ossicle in a 15-year-old boy. B. B. ... Another disadvantage might be the use of a fairly large medial distal tibial osteotomy that has to extend into the tibial plafond in order to be able to excise the entire defect. 1-5 Most studies that report outcomes after these fractures have assessed patients at a single point in time and report an average length of follow up. He is now 3 weeks from injury and skin swelling has subsided significantly. “Pilon,” the French word for pestle, was first used by Etienne Destot in 1911 as an analogy for the mechanical function of the distal tibia on the talus. If both the tibia and fibula are fractured, which is usually the case in the severe cases, it really doesn't matter where the fibula is fractured (mid-shaft, lower shaft, or distally/lateral malleolus), the fixation of the fibula at any level would be included in the code 27828.So the answer to your question is no. Radiology Masterclass, Department of Radiology, A 'pilon' fracture is any fracture of the distal tibia which involves the articular surface of the tibia - also known as the 'tibial plafond', The lateral image demonstrates a step in the tibial plafond, Irregularity or depression of the talar dome surface may represent a significant defect of the bone (osteo) and cartilage (chondro), The talar dome surface is an important review area which should be assessed on all ankle X-rays, A distal tibial fracture passes to the growth plate, Note the normal unfused calcaneal apophysis which should not be mistaken for a fracture. Tested Concept, (OBQ05.93) The injury is closed, and soft tissues are intact upon arrival. 2. Tested Concept, (OBQ06.8) Specific Classifications Systems. The syndesmosis is the fibrous connection between the fibula and tibia formed by the anterior and posterior tibiofibular ligaments - located at the level of the tibial plafond (French for ceiling) - and the interosseus ligament, which is the thickened lower portion of the interosseus membrane. SBCs were first discovered in 1940s, but doctors are still uncertain about the reasons they form. Sinding-Larsen-Johannson syndrome is a traction apophysitis involving the inferior pole of the patella, typically affecting individuals age 10–14.
