2000 Jul-Aug. 8 (4):253-65. The results of the classic study from the Swiss AO group could not, however, be reproduced by all surgeons. J Orthop Trauma. In this group there was always a tibial fragment remaining in the correct relationship to the fibula which could be used to help judge reduction, but failure to recognise and reduce talofibular incongruity led to poor results. The talus has the opposite geometry of the tibial plafond and therefore serves as a perfect template for assessing articular reduction of the distal tibia. 1a-c). Last modified Apr 05, 2012 09:33 ver. Rüedi-Allgöwer classification and AO/OTA classification for Pilon fractures are widely used until now. The latest insights in diagnosis, classification and surgical treatment of tibia plateau and pilon fractures are reviewed. Tang (2012) proposed a four-column classification which has some similarities to the Topliss classification but omits central fragments. Irreversible damage to the articular cartilage, and at times the soft tissues, occurs at the time of injury. These principles (perhaps with #3 optional), restoration of articular surface, realign joint surface to shaft, then bridge metaphyseal comminution with fixation, can be applied to any periarticular fracture. Pilon fractures, or fractures of the tibial plafond, range from low- to high-energy axial-loading injuries. The most widely accepted open fracture classification is credited to Gustilo and Anderson. A pilon fracture, is a fracture of the distal part of the tibia, involving its articular surface at the ankle joint.Pilon fractures are caused by rotational or axial forces, mostly as a result of falls from a height or motor vehicle accidents. tension band. Your voice Feedback and feature suggestions. Gustilo type 1 open fractures are generally clean with a < 1-cm skin laceration. The superficial peroneal nerve pierces the fascia of the lateral compartment ~ 12 cm proximal to the ankle joint en route to provide sensation to a majority of the dorsum of the foot. Traditional classifications of Pilon fractures, either Ruedi-Allgower classificationor AO/OTA classification, are unable to describe all types and complexities of Pilon fractures and have limited contribution to … The AO long bone group universal classification of fractures groups distal tibia fractures as 43 and divides this into: 43A: extra-articular – most would not recognise these as pilon fractures, although they appear in some series 43B: partial articular fractures with some connection between part of the joint surface and the diaphysis Fracture and Dislocation Classification Compendium–2018, Journal of Orthopaedic Trauma. AO/OTA Fracture and Dislocation Classification Long-bone Fractures 41B Partial articular 41B1 Split 41B2 Depression 41B3 Split depression 41C Complete articular 41C1 Simple articular, simple metaphyseal 41C2 Simple articular, wedge, or multifragmentary metaphyseal 41C3 Fragmentary or multifragmentary metaphyseal 43A Extraarticular 43A1 Simple 2013 Jul. Can be combined with subtypes of A or B. AO Spine Thoracolumbar Classification System Disclaimer: 1. The systems used to classify the displaced distal pilon fractures are supposed to ensure the three-dimensional assessment of the fracture and provide high inter- and intra-observer agreement. What is the most appropriate Gustilo-Anderson classification of this injury? Type 2 Tscherne injury describes advanced muscle contusion and deep, potentially contaminated abrasions. 19-year-old man ... Day 0. Currently the tibial pilon fractures are classified according to Ruedi Allgower and AO classification system , . According to the four-column classification scheme, lateral column of 85 cases, posterior column of 66 cases, medial column of 77 cases, and anterior column of 61 cases are involved. After recovery from pilon fractures, many patients continue to have debilitating pain and ankle stiffness. After recovery from pilon fractures, many patients continue to have debilitating pain and ankle stiffness (Babis et al 1997, Sands et al 1998, Pollak et al 2003). Type A is extra-articular, type B is partially articular, and type C is completely articular. Surgical options include the following: Bridging external fixation, external fixation with limited internal fixation, nonspanning external fixation ± limited internal fixation, and staged open reduction and internal fixation. Computed tomography (CT) examination is best delayed until restoration of length in shortened fractures because ligamentotaxis helps to better approximate fragments closer to their native position, making interpretation easier. Treatment of pilon fractures remains challenging due to the difficulty of fracture reduction and associated soft tissue complications. Surgical timing and type of fixation utilized is largely dictated by the condition of the soft tissues. J Am Acad Orthop Surg. When the ankle is dorsiflexed at the time of injury, pilon fracture patterns involve the anterior articular surface of the tibial plafond. An associated fibula fracture is often present in pilon fractures. A pilon fracture is a type of distal tibial fracture involving the tibial plafond. 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. What are the goals of treatment? In the AO/OTA classification for long bone fractures, pilon fractures are classified as extra-articular (43A), partial articular (43B), and intra-articular (43C), and further subclassified based on the degree of comminution. 1) Muller-AO Classification of distal humeral fractures (also called just Muller or AO or OTA) Similar to AO classification of distal radius A- Extra-articular fracture (Supracondylar) joint-spanning articulated vs. nonspanning hybrid ring. 27(7):e152-6. METHODS: One hundred and ten cases (107 patients) of Pilon fractures classified by the four-column theory and treated by ORIF, were reviewed. The paper should be read in detail - important points include: Topliss compared the reproducibility of their grouping with division into AO "B" and "C" groups. Data Trace is the publisher of Wheeless' Textbook of Orthopaedics Data Trace specializes in Legal and Medical Publishing, Risk Management Programs, Continuing Education and Association Management.. Data Trace Publishing Company 110 West Rd., Suite 227 Towson, MD 21204 Telephone: 410.494.4994 C. Discussion. A diagram summarising fracture alignments is provided, which implies very few fracture lines in intermediate positions between the coronal and sagittal families - it would be valuable to reproduce this in a different data set. Figures. New research was undertaken to determine the best way to manage higher energy fractures of the tibial plafond in response to the higher rates of infection. 10.1055/b-0034-85578 2.2 Fracture classification Principles of Müller AO/OTA Classification of Fractures-Long Bones Describing fracture morphology Conclusion Classification terminology Further reading Author James Kellam 2.2 Fracture classification Fracture classifications have multiple purposes. The articular surface of the distal tibia is concave in both the coronal as well as the sagittal plane. There may be some benefits to this technique with possibly less swelling and stiffness. All fractures were OTA/AO type 23C3. This classification is arranged in order of increasing severity according to the complexities of the fracture, difficulty of treatment, and worsening prognosis. Fracture and Dislocation Classification Compendium–2018, Journal of Orthopaedic Trauma. Dr Daniel J Bell ◉ and Dr Yuranga Weerakkody ◉ et al. The AO long bone group universal classification of fractures groups distal tibia fractures as 43. Diagnosis. The pilon fracture usually has an anterolateral (Chaput) fragment and a posterolateral (Volkmann) fragment. AO Classification of Distal Tibial Fractures A – extra-articular (metaphyseal fracture) ... high energy pilon fractures will take about 4 months to heal; 75% may expect good result (if no wound complications) AO Classification of Distal Tibial Fractures A – extra-articular (metaphyseal fracture) ... high energy pilon fractures will take about 4 months to heal; 75% may expect good result (if no wound complications) Tibialis posterior tendonopathy/adult acquired flatfoot, 43A: extra-articular – most would not recognise these as pilon fractures, although in some series non-articular fractures are included and it can be difficult to tell how many were articular, 43B: partial articular fractures with some connection between part of the joint surface and the diaphysis - again, some series appear to include these but most do not clearly differentiate between them and those with complete separation between diaphysis and metaphysis. In publications, it will be cited as Meinberg E, Agel J, Roberts C, et al. The AO Spine Classification Group reached a consensus on a classification that incorporates both fracture morphology and clinical factors relevant for clinical decision making. In the most severe plafond fracture patterns, the articular segment is fractured into numerous pieces with certain segments driven proximally into the metaphysis, creating marked joint incongruity and associated metaphyseal defects. 236. High-energy fractures are generally due to axial force that drives the talus into the tibial plafond, causing an “implosion” of the articular surface. A pilon fracture is a type of distal tibial fracture involving the tibial plafond. AO Surgery Reference is a resource for the management of fractures, based on current clinical principles, practices and available evidence. The concave tibial plafond provides ~ 40% more posterior than anterior coverage. The AO Spine Thoracolumbar and Subaxial Classification systems are the result of a systematic assessment and revision of the Magerl classification. OrthopaedicsOne Articles. Comminution, which frequently occurs with high-energy pilon fractures, is most typically located in the anterolateral and central regions of the plafond. AO Trauma—Foot & Ankle ... Ankle trauma—pilon fractures. Day 0. In 13 fractures (38%), there was an extension to the radial diaphysis. The importance of this classification is that it is easy to apply. Complications after treatment of tibial pilon fractures: prevention and management strategies. At the level of the ankle, the distal tibia is intimately associated with the fibula through strong ligamentous attachments. The tibial pilon fracture is a rare, yet devastating injury. Anterolateral exposures for pilon fractures risk injury to the superficial peroneal nerve. 2000 Jul-Aug. 8 (4):253-65. The most widely used classification systems for pilon fractures are Ruedi-Allgower and AO (Arbeitsgemeinschaft für Osteosynthesefragen) , but concern has been raised over the accuracy and reproducibility of these 2 classifications (7, 8), which are X-ray based. Appreciate the consistent Y pattern creating 3 main articular fragments. 1/3 of patients have associated injuries . Explanation. Classification. Posterior partial fracture overlap with malleolar fractures with posterior malleolar components (Klammer 2013), and anterior partial fractures were included by Lauge-Hansen (1950) iin his classification of malleolar fractures, 43C: complete articular fractures with no connection between the joint surface and diaphysis – most pilon fractures fall into this group, 43C1: no comminution of epiphysis or metaphysis, 43C2: comminution of metaphysis but not epiphysis, 43C3: comminution of epiphysis +/- metaphysis (corresponding roughly to Ruedi-Allgower group III, many pilon fractures are in this category). Cole PA, Mehrle RK, Bhandari M, Zlowodzki M. The pilon map: fracture lines and comminution zones in OTA/AO type 43C3 pilon fractures. Pilon (tibial plafond) fractures - Ruedi and Allgower classification. none have been shown to be superior with respect to ankle stiffness; 2 tibial shaft half pins connected to hindfoot half pins or calcaneal transfixation pin Day 0. A common modern algorithm is to apply a spanning external fixator to maintain length urgently following injury. The most common fracture pattern occurs with the ankle in dorsiflexion (i.e., the foot on the brake pedal during a motor vehicle accident). Impaction most commonly occurs at the dome between the 3 main fracture fragments. Day 0. Destot coined the term pilon, as he thought that the distal tibial metaphysis resembled a pharmacist’s pestle. Besides lectures and video presentations, patient cases will be discussed. Limited ORIF to improve articular reductions without formal operative exposures was then employed to supplement external fixation strategies. Initial splinting in the emergency room decreases further soft tissue trauma, and fracture dislocations should be reduced with adequate anesthesia to restore joint alignment. 27(7):e152-6. AO/OTA Fracture and Dislocation Classification Compendium—2018. Open wounds are covered with moist gauze, and antibiotic and tetanus protocols are employed. Introduction. He classifies ankle fractures according to the level of the fibular fracture. 1-10% of LE fx’s . . Primary fracture lines of 40 OTA-type 43C3 fractures are shown. Some surgeons have found that immediate (within a few hours of injury) open reduction, prior to significant swelling, can be performed safely. The series reported by Ruedi and Allgower described superior outcomes after formal open reduction and internal fixation (ORIF) in their patient population with few major complications. 2000 Jul-Aug. 8 (4):253-65. A pilon fracture is a type of break that occurs at the bottom of the tibia (shinbone) and involves the weight-bearing surface of the ankle joint. These are considered to represent 1-10% of all lower limb fractures 6. More recently, the AO/OTA classification of pilon fractures has been utilized. The tibial pilon fracture is a rare yet devastating injury. 43C patterns are high-energy injuries with a compromised soft tissue envelope. Pilon tibiale fractures with significant joint involvement (AO-classification B2/3 and C2/3) are considered one of the most unfavourable injuries of the lower extremity. The systems used to classify the displaced distal pilon fractures are supposed to ensure the three-dimensional assessment of the fracture and provide high inter- and intra-observer agreement. AO Surgery Reference is an internet-based resource for the management of fractures, based on current clinical principles, practices and available evidence. Central articular (implosion) injury is the result of an axial load on the foot in neutral position. Initial external fixator constructs spanned the ankle joint until fracture union, resulting in unacceptable ankle stiffness. Insert figures illustrating the classification. These are considered to represent 1-10% of all lower limb fractures 6. Open fractures with vascular injury requiring repair along with extensive soft tissue compromise are considered type 3C. Fractures of the distal tibia have been given the number 43 in the AO Classification (Fig. Although many pilon fractures are open injuries, closed fractures have significant soft tissue compromise as well. According to the AO/OTA classification, 17 patients had type B fracture and 14 patients type C fractures. Once the swelling has peaked and regressed 1-3 weeks after injury, open reduction of the tibia (and fibula) can be performed with removal of the temporary external fixator. J Orthop Trauma. Soft tissue injury has been standardized using the method of Tscherne for closed fractures and the Gustilo-Anderson classification for open injuries. J Am Acad Orthop Surg. Recognition of a different category of higher energy pilon injuries emerged, which was quite different than those treated by Ruedi and Allgower, who treated lower energy injuries primarily in healthy skiers: So-called “boot top injuries.”. METHODS: One senior attending, two fellows (one trauma, one foot and ankle), one junior orthopaedic resident, and one experienced research coordinator independently classified eighty-four sets of radiographs. The AO classification, although comprehensive, is complicated and difficult to apply. The 2018 revision of the AO/OTA Fracture and Dislocation Classification Compendium for adults and children addresses the many suggestions to improve the application of the system, as well as add recently published and validated classifications. Type 3B are usually contaminated with extensive periosteal stripping and bone exposure necessitating flap coverage. Cole PA, Mehrle RK, Bhandari M, Zlowodzki M. The pilon map: fracture lines and comminution zones in OTA/AO type 43C3 pilon fractures. With this type of injury, the other bone in the lower leg, the fibula, is frequently broken as well. 2013 Jul. A severely traumatized soft tissue envelope accompanies the higher energy pilon fractures. Thordarson DB. Pilon fractures, or fractures of the tibial plafond, range from low- to high-energy axial-loading injuries. . The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. 4. These classifications are less reproducible and do not provide necessary information for proper surgical planning. Volume 32: Number 1; Supplement, January 2018. Principle 4: Buttressing of the tibial metaphysis is then required while connecting the articular block to the diaphysis. The compendium is branded as the AO/OTA or OTA/AO Fracture and Dislocation Classification Compendium. In the AO/OTA classification for long bone fractures, pilon fractures are classified as extra-articular (43A), partial articular (43B), and intra-articular (43C), and further subclassified based on the degree of comminution. Code fractures and dislocations with the AO/OTA Fracture and Dislocation Classification 2018 for adults and pediatrics. a group of fractures with "functional diastasis" of the tibiofibular articulation because of separation between the main block of distal tibia and fragments still attached to the fibula. Management selection. 2000 Jul-Aug. 8 (4):253-65. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the predecessor of the AO Foundation. The Topliss classification was more reproducible, especially in the hands of Topliss herself, although no statistical analysis is provided. Complications after treatment of tibial pilon fractures: prevention and management strategies. Ruedi-Allgower type 1 fractures are minimally displaced cleavage fractures, in contrast to type 2 injuries, which are displaced. The classical Chance fracture. Initial management of pilon fractures depends as much on the soft tissue as the bony injury. Pilon Fractures Philip Wolinsky . The AO long bone group universal classification of fractures groups distal tibia fractures as 43. 8 Three types are included in Rüedi-Allgöwer classification, depending on the displacement of articular surface, metaphyseal and injury extent of fractures, which is easy to remember and to evaluate the outcome of pilon fractures. The most widely used classification systems for pilon fractures are Ruedi-Allgower (5) and AO (Arbeitsgemeinschaft für Osteosynthesefragen) (6), but concern has been raised over the accuracy and reproducibility of these 2 classifications (7, 8), which are X-ray based. The tendinous and neurovascular structures are covered proximally by the investing fascia of the anterior compartment and distally by the extensor retinaculum. Plafond is also a French term, described by Bonin, referring to the distal tibial articular surface as the roof (ceiling) of the ankle joint. Other common complications seen following treatment of tibial pilon fractures are arthrofibrosis and posttraumatic arthritis. They should facilitate communication among physicians and be useful for … There are subtypes of each classification based on increasing complexity of the articular and metaphyseal components ( Fig. In the vast majority of pilon fractures, the fracture lines propagate from the fibular incisura laterally in the shape of a Y to exit anterior and posterior to the medial malleolus. In publications, it will be cited as Meinberg E, Agel J, Roberts C, et al. The AO/OTA classification system provides a comprehensive description of distal tibial fractures. This relatively rare injury (< 10% of lower extremity fractures) usually occurs in adults (aged 30s to 40s) owing to a fall from height or a motor vehicle crash [ 6 ]. Examination should document the presence of both closed and open soft tissue injury as well as location and extent of lacerations, abrasions, and contamination. University of California at Davis Medical Center . A systemic motor and sensory examination is warranted in addition to documentation of distal pulses. Unsatisfied with the limitations of external fixation strategies, including compromised articular reduction, pin tract complications, and patient dissatisfaction, new strategies to allow for ORIF were investigated. The superficial peroneal and saphenous nerves are superficial to the fascia. Explore AO Trauma's varied teaching and learning materials to enhance your expertise. Although the Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Orthopaedic Trauma Association (OTA) classification system is the most widely accepted fracture classification system, the Ruedi-Allgower system is the classic fracture scheme often known and used for this injury throughout the world. Volume 32: Number 1; Supplement, January 2018. They run together in the pericapsular fat between the extensory digitorum and extensor hallucis longus tendons. Axial CT shows fracture lines dividing the plafond into 3 major fragments: Anterolateral, posterior, and medial. Classification of distal tibial fractures AO Classification. (OBQ12.156) A 36-year-old male sustains an open segmental tibia fracture associated with an overlying 8 cm soft tissue avulsion that requires skin grafting for soft tissue coverage. C Displacement or dislocation The re are no subtypes because various configurations are possible due to dissociation/ dislocation. Dear Visitor, Your browser is currently not set to accept cookies. Cole PA, Mehrle RK, Bhandari M, Zlowodzki M. The pilon map: fracture lines and comminution zones in OTA/AO type 43C3 pilon fractures. Reports describing ORIF of tibial pilon fractures revealed a concerning complication rate with higher energy pilon fractures, including wound problems, deep infection, nonunion, and malunion (McFerran et al 1992, Teeny and Wiss 1993). Thordarson DB. When the fibula was intact, 58% of fractures were partial articular type B. J Orthop Trauma. Despite the best treatment, patients sustaining high-energy pilon fractures generally do not return to their previous state of general health or function. The AO group has developed a comprehensive classification of fractures. Type 3A open fractures have adequate soft tissue coverage over the fracture. Thordarson DB. Pilon fractures in the distal tibia result from axial forces that can range from low to high energy and produce a spectrum of articular and metaphyseal injuries. This is still an emerging technique, and the risk of opening a pilon fracture during the initial stages of swelling could be devastating. The classification system, broken into three categories focuses on the displacement and pattern of the fracture and the integrity of the coracoclavicular ligaments. 27(7):e152-6. Fracture classification. Moderate interobserver reliability makes the AO/OTA system reliable for classifying pilon fractures (Swiontkowski et al 1997). The authors describe how this influences surgical approach but the data do not clarify this and the classification may need some further development to make a distinct contribution to decision making. The AO Spine classification of thoracolumbar injuries is one of the more commonly used thoracolumbar spinal fracture classification systems and aims to simplify and universalise the process of classifying spinal injuries and improve interobserver and intraobserver reliability 3.. Fragments usually remain attached to the distal fibula segment by the anterior and posterior tibiofibular ligaments. It describes the complete surgical management process from diagnosis to aftercare for fractures in a given anatomical region, and also assembles relevant published AO material. ... posterior malleolar fracture.The standard AO classification of ankle fractures is adapted from that of Danis. Principle 1: Length and rotation is restored by ORIF of the fibula. OBJECTIVES: To evaluate the interobserver variation for the AO/OTA fracture classification system: region forty-three-pilon fractures. The AO classification of clavicular fractures along with the Neer classification system is one of the more frequently used classification systems when assessing distal clavicular fractures.. C2 pilon fracture treated with the MIPO technique. Sclerosis is due to impacted bone fragments/trabeculae. In: OrthopaedicsOne - The Orthopaedic Knowledge Network. 110.2 ) … This new comprehensive AO CMF classification system for fractures in the adult craniomaxillofacial skeleton is organized in anatomic modules in a three precision-level hierarchy with a brief account of increasing complexity and other details: Level-1 Most elementary. Type A fractures are extraarticular distal tibial fractures, which are subdivided into groups A1, A2, and A3, based on the amount of metaphyseal comminution. No vascular injury is identified. Insert figures illustrating the classification. Get started now. Principle 2: Anatomical reconstruction of the articular surface of the tibial plafond is performed after the acute phase of the injury. This classification is arranged in order of increasing severity according to the complexities of the fracture, difficulty of treatment, and worsening prognosis. According to the Fernandez classification, 26 patients (76%) had type 5 fractures, and 8 patients (24%) had type 3 fractures. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the predecessor of the AO Foundation. 2013 Jul. 2013 Jul. Abstract Actually, pilon fractures are classified according to AO and Ruedi Allgower classification systems based on X-rays. The tendons of the anterior compartment, the dorsalis pedis artery, and the superficial and deep peroneal nerves can be encountered with anterior exposures at the level of the ankle joint. Classification of distal tibial fractures AO Classification. A pilon fracture, is a fracture of the distal part of the tibia, involving its articular surface at the ankle joint.Pilon fractures are caused by rotational or axial forces, mostly as a result of falls from a height or motor vehicle accidents. The compendium is branded as the AO/OTA or OTA/AO Fracture and Dislocation Classification Compendium. In the AO/OTA classification for long bone fractures, pilon fractures are classified as extra-articular (43A), partial articular (43B), and intra-articular (43C), and further subclassified based on … There simply is not a lot of soft tissue around the distal tibia, as compared to more proximal parts of the leg. Principle 3: Metaphyseal bone defects are bone grafted to buttress the articular surface. Spectrum of injuries: 1) Low energy rotational fx’s Ankle type fractures / Skiing, simple falls . Traction views may be valuable for further characterization of the pilon fracture. Again, failure to recognise and correct this led to poor results.
