This frame configuration is especially useful in patients who are treated late (and require bilateral distraction to regain length) and in those injuries where the fibula cannot be fixed at the initial operative procedure. 34.2).3 This classification system is much more detailed, describes comminution at multiple levels, and differentiates between partial and complete articular injuries. Bone scintigraphy 2 weeks later shows stress fractures of the distal … CT ankle for spiral distal third tibia fracture . The combination of fracture pattern, associated soft tissue condition, open wounds, patient comorbidities, and surgeon comfort determines the surgical approach(es) to be used. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. For example, if the original injury film demonstrates significant varus angulation of the distal tibia, a medial buttressing implant is likely indicated to counteract the inherent tendency for this injury to fail back into varus. The AO Foundation/Orthopaedic Trauma Association (AO/OTA) fracture classification was published as a compendium to the Journal of Orthopaedic Trauma (JOT) in 1996. However, in cases of severe metaphyseal impact, metaphyseal bone loss, or osteopenia, there may be a role for these implants.

The relevant surgical anatomy for the fixation of tibial pilon fractures includes osseous, ligamentous, muscular, and neurovascular structures. Classification of distal fibula fractures attempts to split fractures into groups by severity. Conversely, comminuted or wedge fractures proximal to the ankle joint line are typical of valgus overload compressive fractures. CT scans obtained with the extremity in its initial shortened position are frequently of low value due to significant displacement of the fracture fragments and talar shortening. The indications for surgical treatment are based on the combination of fracture location, fracture pattern, and the associated soft tissue injury. type III: marked comminution as well as articular impaction. A 4-mm pin placed transversely across the midfoot from medial to lateral in the cuneiforms is attached to the proximal tibial pin and maintains the foot in a neutral position. The anterolateral approach (Fig. However, for the purposes of describing these injuries and formulating a surgical plan, the fracture group (e.g., C1, C2, or C3) can be helpful. The anterior tibial compartment contains, from medial to lateral, the tibialis anterior, the extensor hallucis longus (EHL), the extensor digitorum communis (EDC), and the peroneus tertius. 5. The surgical management of distal tibia diaphyseal fractures (OTA Classification Type 42A, 42B, and 42C) and distal metaphyseal tibia fractures with or without intraarticular extension (OTA Classification Type 43A, 43B1 or 43B2, and 43C1 or 43C2) with an intramedullary implant can be successfully performed with the utilization of appropriate aids and proper techniques. J Bone Joint Surg Br. Distal tibial physeal fractures can be described using a number of classification systems. This classification can help dictate treatment as well as predict outcomes and rate of complications associated with individual fracture. An open distal tibia fracture with a relatively simple articular injury but with a complex distal fibular fracture. The relevant anatomy of the talus includes an understanding of the nonarticular portions because these can be used for placement of Schanz pins that are useful in distraction across the ankle joint. 2001;32 (1): 91-102. Haapamaki VV, Kiuru MJ, Koskinen SK. Classification. The associated soft tissue injury that occurs is frequently more important than the fracture pattern. Early limb realignment to relieve skin pressure from the osseous deformity should be performed. Fracture blisters, local skin necrosis, and impaired distal perfusion are commonly observed. Useful techniques in difficult or comminuted cases include preliminary application of a medial (tibia to calcaneus) external fixator or femoral distractor to regain length, distal fibular plate fixation with application of a proximal push screw to regain length, and application of a small distractor directly to the fibula (Fig. distal tibia forms an inferior quadrilateral surface and pyramid-shaped medial malleolus; articulates with the talus and fibula laterally via the fibula notch; Vascular anatomy . Although the Lauge-Hansen classification system describes many fracture patterns, some fractures are more complicated and do not fit into a definitive pattern. Cheung Y, Perrich KD, Gui J et-al. ... CT is also helpful for exact fracture classification 1. Check for errors and try again. Radiology Department of the Rijnland Hospital, Leiderdorp, the ... you need to understand the classification of ankle fractures and exorotation injuries that were highlighted in Ankle - Fractures 1 and 2. posterior malleolus fracture. The relevant osseous anatomy of the tibial pilon includes the distal tibia, the distal fibula, and the talus. 6-28, also Fig. Swelling occurs rapidly and may be exacerbated by the shortening that occurs. 1 Using the principles of the Comprehensive Classification of Fractures of the Long Bones (CCF) developed by Müller and collaborators, the OTA classification committee classified and coded the remaining bones. Review of the fibular fracture characteristics, combined with the coronal plane angulation of the tibia, provides visual clues regarding the areas of compression and tension failure. The articulating distractor-compressor clamp can be used to regain length with a standard external fixator. Posterior malleolus fractures are fractures of the posterior segment of the tibial plafond and a common occurrence in the setting of bimalleolar or trimalleolar ankle fractures. Rupture of the anterior syndesmosis - seen as widening of the space between the distal tibia and fibula (lateral clear space). The Salter-Harris classification is a means of categorizing epiphyseal plate fractures and provides clues to their prognosis All such these fractures, by definition, involve or extend through the epiphyseal plate so that all such fractures occur in children before the epiphyseal plate closes anterior tibial artery . The Toronto experience 1968–1975.” The talus should be accurately reduced and centered in line with the central axis of the tibia (Fig. The sagittal and coronal reformations provide additional data, especially for identifying impacted segments that are rotated relative to the axial images. Petit P, Panuel M, Faure F. Acute fracture of the distal tibial physis: role of gradient-echo MR imaging versus plain film examination. Some important principles include placement of all pins remote from any anticipated surgical incisions, avoidance of pin placements into the talus if any anterior exposure is planned, and pin placement into subcutaneous locations to minimize pin-site irritation and drainage. The initial surgical management of tibial pilon fractures requires planning for subsequent procedures based on the injury pattern, associated open wounds, and soft tissue swelling. Laterally, there is significantly more room available at the talar neck than on the medial side. Physical examination of the injured lower extremity should include a careful assessment of the local swelling, perfusion, and neurologic deficits. 6 Fractures in each type are then classified on the basis of fracture comminution into one of three groups, each of which can be further subdivided into three subgroups based upon other fracture … Stabilization of either or both the midfoot and the forefoot is still required to maintain the foot in neutral dorsiflexion. The indications for nonoperative management of displaced, articular tibial pilon fractures are extremely limited. The importance of an accurate reduction of the fibula cannot be overemphasized. The injury radiographs should be evaluated to determine the primary deformity pattern because this in turn determines the final fixation construct and hence the surgical approach(es) necessary. anterior tibial artery . The Weber criteria relates the position of the distal fibula fracture to the syndesmosis (4). Triplane fracture of the distal tibia. The presence of open wounds, a failure to obtain or maintain adequate alignment, and other extremity injuries are among the indications for operative fixation. Nondisplaced fractures may similarly require operative fixation if early motion of the ankle is desired. One successful strategy involves construction of a medial triangular external fixator that relies on an intact or plated fibula, against which tension can be applied. Conversely, large implants are rarely needed to support cortical bone that has failed in tension if the compression failure side has been supported. 20, No. 2007;127 (1): 55-60. As the complexity increases, the number of fragments and the associated comminution increase. The formulation of a cogent preoperative surgical plan begins with the evaluation of the injury films. Pictorial Review: Cross-Sectional Imaging of the Foot and Ankle. AJR Am J Roentgenol. Tibial stress fractures are most often found in distance runners, in whom normal bone is subjected to repetitive microtrauma such that the rate of osteoclastic resorption exceeds the rate of repair. Open fractures require careful preoperative planning about the placement of incisions for the surgical extension of open wounds to enable an adequate debridement. Distal tibial triplane features, which constitute 6%-10% of epiphyseal injuries, are most accurately delineated and analyzed with computed tomography (CT). The condition of the surrounding soft tissues should help direct the choice of treatment, each of which has specific advantages. Video 34.3 Ankle-Spanning External Fixator. Locking plates are of minimal use in most distal tibial pilon fractures. 15.11). One of the most important factors in choosing the appropriate surgical approach for a given injury is the location of the fracture lines and the associated comminution.9,10 The most frequently used approaches for articular injuries are the anterolateral and the anteromedial. Schatzker II: splitting and depression of the lateral tibial plateau; namely, type I fracture with a depressed component. The initial radiographic evaluation consists of standard ankle and tibial radiographs. Injuries and occur as a component of most C-type tibial pilon fractures healing!
