Avoid the peroneal nerve which runs posterior to the biceps femoris tendon at its attachment to the fibular head. Type 3B are usually contaminated with extensive periosteal stripping and bone exposure necessitating flap coverage. This procedure is normally performed with the patient in a supine position. The fibula anatomical reduction is essential if posterolateral and anterolateral tibial articular fragments are to be reducible. The choice of whether to use a locking implant is determined by: There are multiple commonly observed articular injuries that increase the complexity of multifragmentary metaphyseal fractures. In these patterns, lateral or anterolateral buttressing is optimal and medial fixation can be less strong. Skin incision Make a straight incision lateral to the patella. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The tibial pilon fracture is a rare, yet devastating injury. Complex Tibial Plateau Fractures: A Direct . Careful assessment is necessary. Conclusions: AO 43-B anterior impaction tibial plafond fractures have a worse clinical outcome compared to AO 43-B nonanterior impaction fractures. Lauge-Hansen N (1950) Fractures of the ankle. External rotation injury of the ankle is the most common ankle injury and can lead to a Weber B or Weber C fracture. Fragments usually remain attached to the distal fibula segment by the anterior and posterior tibiofibular ligaments. - minimal or no anterior tibial cortical communition, two or more large tibial articular fragments, and usually an oblique or transverse fibular fracture at level of the plafond (or ankle joint ); - type B: - results from severe axial compression force, causing distal tibial bony impaction and comminution; - Surgical Treatment: - controversies: The distal pin, anterior to the axis of rotation of the talus, produces ankle joint distraction and plantarflexion, maximizing articular visualization. 4, 5 . P. Stahel 02:31. If necessary release the ilio-tibial tract by incising it or taking a small flake of bone from Gerdy's tubercle. Fibular malreduction is a pitfall, particularly during emergency fixation of multifragmentary fractures. Preliminary articular reduction was obtained, and K-wires were placed. Anterolateral comminution is commonly encountered with high-energy fractures. Objectives: To determine whether patients with AO/OTA 43-B anterior impaction tibial plafond fractures have worse clinical outcomes, and an increased risk of progression to ankle arthrodesis. When the ankle is dorsiflexed at the time of injury, pilon fracture patterns involve the anterior articular surface of the tibial plafond. The anterolateral fragment is rotated internally to complete the reduction of the pilon. Intraoperative articular visualization was optimized with a distractor spanning from the mid-tibia to the talar neck. floating knee is an indication for antegrade tibial nailing and retrograde femoral nailing. This assists with proper positioning of the posterolateral tibial articular fragment (from the attachment of the posterior tibiofibular ligaments) and, in turn, with reduction of the talus relative to the tibial shaft. 1. Combined experimen-tal-surgical and experimental-roentgenologic . Comminution, which frequently occurs with high-energy pilon fractures, is most typically located in the anterolateral and central regions of the plafond. Like other fractures, they are divided into three groups subject to the severity and complexity of the respective injury 1: Isolated medial malleolar fractures and isolated posterior malleolar or Volkmann fractures are classified as partial articular distal tibial end segment fractures as long as there is no fibular fracture. Implant removalImplant removal may be necessary in cases of soft-tissue irritation by the implant (plate and/or isolated screws). PMID: 10709022 Mechanism Typically high energy injuries and occur as a result of an axial loading which drives the talus into the tibial plafond. In severe cases, numbness or "pins and needles" in the foot due to nerve damage. This article provides a systematic review of the clinical and functional outcomes of TPFs treated specifically with circular external fixation (CEF). In the illustrated case, fixation of the posterior fragment was performed acutely through a limited posteromedial approach at the time of initial bridging external fixation. 22 (6 . Setting: Level 1 academic trauma center. Low-energy fractures typically occur due to rotational forces imparted to the distal tibia. Meinberg E, Agel J, Roberts C, Karam M, Kellam J. Fracture and Dislocation Classification Compendium-2018. (Tscherne classification, closed fracture grade 0, rarely grade 1). Definitive reconstruction of the articular surface is delayed until the soft tissues allow. Tibial Plafond Fractures - University of Iowa. Conclusions AO 43-B anterior impaction tibial plafond fractures have a worse clinical outcome compared to AO 43-B nonanterior impaction fractures. The methods of treatment were divided into two groups: open reduction and rigid internal fixation by the AO . Pilon fractures can occur from both low- and high-energy mechanisms. Proximal screw fixations were placed through small incisions. Prior to closure, reduction and stability must be reconfirmed (see also the content on assessment of reduction). Note: To engage the posterolateral fragment, a small incision is placed at the posterolateral border of the fibula. Note: The medial plate can be slid subcutaneously through a small (2 cm) incision. The operative principles described by the AO group for operating pilon fractures serves as a working paradigm for ORIF of these injuries. Fracture comminution may indicate the need for supplementary plate fixation, Associated soft-tissue envelope that may contraindicates the use of supplementary plate fixation. tibial plafond fractures. Dec 416, 2022, Revised proximal femur module is now online, Reconstruction of the tibial joint surface, Use of autogenous cancellous or corticocancellous bone graft (if necessary). Both implants were placed through limited incisions using minimally invasive techniques. We assumed that the intact distal tibial plafond as well as the medial and lateral ankle ligaments provide stability for the ankle joint on the sagittal plane; pilon fractures cause impaction of . The articular surface of the distal tibia is concave in both the coronal as well as the sagittal plane. The two typical locations are at the lateral aspect of the medial malleolus and at the medial aspect of the anterolateral fragment. Traction views may be valuable for further characterization of the pilon fracture. Ligamentous attachments are usually intact. Soft tissue injury has been standardized using the method of Tscherne for closed fractures and the Gustilo-Anderson classification for open injuries. Options to consider include the number of plates as well as their stiffness, strength, and location. Check for errors and try again. The word "pilon" comes from the French root meaning "pestle" or "rammer," conveying the idea that the talus drives into the tibial articular surface. Usually, there are three main joint fragments. Principle 1: Length and rotation is restored by ORIF of the fibula. Outcomes and Complications With Treatment of Open Tibial Plafond Fractures With Circular External Fixator - Ahmed M. Thabet, Christopher Gerzina, Francesco Sala, Soyoung Jeon, Giovanni Lovisetti, Amr Abdelgawad, Thomas A. DeCoster, Wael Azzam, 2021 Intended for healthcare professionals MENU Search Browse Resources Authors Librarians Editors EN. Tscherne grades 0 and 1 have negligible soft tissue injury and superficial abrasions/contusion, respectively. If the fibula remains unstable, more stable tibial fixation may be advisable. Release the proximal attachment of the tibialis anterior muscle. It is important to use blunt dissection and the appropriate soft-tissue protection sleeves during pin placement. Principle 2: Anatomical reconstruction of the articular surface of the tibial plafond is performed after the acute phase of the injury. The aim of the current study is to introduce a joint . An associated fibula fracture is often present in pilon fractures. The tendinous and neurovascular structures are covered proximally by the investing fascia of the anterior compartment and distally by the extensor retinaculum. See also the content on assessment of reduction. A temporary joint bridging external fixator is typically replaced with a distractor during definitive articular surface reduction and fixation. Authors SK Bonar 1 , JL Marsh Affiliation 1 Department of Orthopaedic Surgery, University of Iowa Hospitals and Clinics, Iowa City. For pilon fractures with a valgus deformity, lateral metaphyseal comminution is commonly observed, and the medial distal tibia typically fails in tension. It is generally advisable to proceed in two or more stages: Open pilon fractures are often very severe injuries that may require plastic surgery for soft-tissue reconstruction. Displacement of the posterolateral and medial segments, typically in the sagittal plane, may also require correction. Reconstruction of the tibial articular surface may be possible at the same time and should be considered if the exposure for flap coverage allows. Principle 1: Length and rotation is restored by ORIF of the fibula. This area is exposed through a posteromedial approach. To allow the reduction to be completed, fixation of the central impacted segment must be out of the way of additional articular fragments. Open wounds are covered with moist gauze, and antibiotic and tetanus protocols are employed. Manual of Fracture ManagementFoot and Ankle examines the techniques and procedures for the management of fractures and dislocations of the foot and ankle. Gustilo type 1 open fractures are generally clean with a < 1-cm skin laceration. An osteotome or elevator can be used to disimpact the articular surface and bone graft can be placed above the articular surface. Wires placement should not interfere with the more anterior reductions. For tibial pilon fractures in adults, the authors illustrate the distinction between closed lesions and lesions involving . Central articular (implosion) injury is the result of an axial load on the foot in neutral position. 1994 Nov;2 (6):297-305. doi: 10.5435/00124635-199411000-00001. At the time of closure re-attachment of the meniscus and capsule is mandatory.

Tibial Plafond Fractures Basics Description Tibial plafond ("pilon") fractures involve the distal articular surface of the tibia and extend to the metaphysis. Plafond is also a French term, described by Bonin, referring to the distal tibial articular surface as the roof (ceiling) of the ankle joint. Tibial plafond fractures occur just above the ankle joint and involve that critical cartilage surface of the ankle. 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). A second 4 mm Schanz pin is placed from lateral to medial into the tibial shaft, proximal to the intended plate. Immobilization is not necessary. For the former reduction sequence, the centrally impacted segment is temporarily stabilized to the posterolateral fragment with two small K-wires. The cases of one hundred and forty-two patients with 145 fractures of the ankle joint that involved the tibial plafond were reviewed. It is an uncommon. The joint arthrotomy is repaired. mechanism of Tibial Plafond Fractures high energy axial load (motor vehicle accidents, falls from height) pathoanatomy of Tibial Plafond Fractures often characterized 3 fragments typical with intact ankle ligaments: 1. medial malleolar (deltoid ligament) 2. posterolateral/Volkmann fragment (posterior inferior tibiofibular ligament) The anterolateral fragment is rotated externally on the anterior tibiofibular ligamentous hinge to allow visualization of the remaining articular segments. Note: The course of the anterior compartment neurovascular bundle, and also the superficial peroneal nerve, should be considered during pin placement. Anterolateral exposures for pilon fractures risk injury to the superficial peroneal nerve. A common modern algorithm is to apply a spanning external fixator to maintain length urgently following injury. The definitive open reduction and internal fixation (ORIF) was performed after the wound was healed without infection and soft tissue swelling had subsided. Cyril Mauffrey. At the level of the ankle, the distal tibia is intimately associated with the fibula through strong ligamentous attachments. This is still an emerging technique, and the risk of opening a pilon fracture during the initial stages of swelling could be devastating. The AO/OTA classification is one of the most frequently used systems for classifying distal tibial fractures or tibial distal end segment fractures. Orthop Traumatol Surg Res 103(7):1099-1103 16. Placed appropriately, they can help support central comminuted areas. Principle 3: Metaphyseal bone defects are bone grafted to buttress the articular surface. Tibial plafond fractures, especially the AO/OTA type C3 ones that take place in young patients with excessive facet fragmentation and cartilage loss that preclude anatomical reduction and effective internal fixation, are devastating situations that often subject to primary arthrodesis. Note: Care must be taken during plate placement to ensure that the plate is slid directly against the tibia to avoid damage to the neurovascular bundle. An anteromedial approach is preferable for its application. They run together in the pericapsular fat between the extensory digitorum and extensor hallucis longus tendons. This volume describes the anatomic and radiological classification of these fractures and discusses contemporary treatments. In multifragmentary metaphyseal fractures, definitive internal fixation often includes lateral and medial plate fixation which span from the articular block to the tibial diaphysis. Indications for closed reduction and cast treatment of pilon fractures are limited. Fracture lines were mapped from axial CT cuts 3 mm above the plafond after an external fixator had been applied. If they are associated with a lateral ankle injury or a fibular fracture they are coded as a malleolar segment fracture 1. The operative principles described by the AO group for operating pilon fractures serves as a working paradigm for ORIF of these injuries. In the illustrated case, definitive articular reconstruction of the anterior fractures was delayed for 16 days. A CT scan was obtained after external fixation to allow for an accurate assessment of the articular injury. Sometimes, they are characterized by concomitant fibular fracture and distal tibiofibular syndesmosis injury. Initial attempts at reduction of the articular surface are often unsuccessful. This term has further been used to portray the mechanism involved in tibial pilon fractures in which the distal tibia acts as a pestle with heavy axial forces over the talus basically causing the . The most widely accepted open fracture classification is credited to Gustilo and Anderson. Background Comminuted intra-articular tibial pilon fractures can be challenging to manage, with high revision rates and poor functional outcomes. However, conventional straight plates must be contoured to fit the bone. An additional long surgical exposure of the medial tibia should be avoided. Distal screws are placed from anterior to posterior engaging the major articular fragments. Operative treatments include internal and external fixation modalities. OBJECTIVES To evaluate the interobserver variation for the AO/OTA fracture classification system . 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. Close the remaining soft tissues in a routine manner. Jens Storm. The specific implant is less important than the reduction and the plate function. Unable to process the form. Additionally, plantarflexion of the foot is frequently necessary. 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). There simply is not a lot of soft tissue around the distal tibia, as compared to more proximal parts of the leg. Scribd is the world's largest social reading and publishing site. Early limited internal fixation of diaphyseal extensions in select pilon fractures : upgrading AO/OTA type C fractures to AO/OTA type B. J Orthop Trauma. Introduction. Fractures of the distal tibia with joint involvement are relatively infrequent, less than 1% of lower extremity fractures, but at the same time one of the injuries that most challenges the technical skill and clinical judgment of the orthopedic surgeon in its management [].Initially called "tibial pilon" by Destot in 1911; it was Bonin who coined the term "tibial plafond" in 1950, as a . Some surgeons have found that immediate (within a few hours of injury) open reduction, prior to significant swelling, can be performed safely. Initial management of pilon fractures depends as much on the soft tissue as the bony injury. Tibial Plafond Fractures Pathway Updated: 10/9/2017. The tibial pilon fracture is a rare yet devastating injury. The surgical approach and implants are determined based on the remaining fracture configuration. 2018;32 Suppl 1(1):S1-S170. Irreversible damage to the articular cartilage, and at times the soft tissues, occurs at the time of injury. The distal tibia is designated as #43 (4 = tibia, 3 = distal segment). tibial plafond to the posterior edge of stable tibial plafond (L STP, length of stable tibial plafond); (3) IAIF sagittal . Principle 4: Buttressing of the tibial metaphysis is then required while connecting the articular block to the diaphysis. A severely traumatized soft tissue envelope accompanies the higher energy pilon fractures. With complex fibular fractures, it may be better not to fix the fibula in the first stage. The fractures are divided into types and further into groups then subgroups. If lag screws are in place and reduction is stable, the distractor can be removed to facilitate plate insertion and placement. Design: Retrospective cohort study. Through a carefully selected collection of 59 cases covering a comprehensive range of foot and ankle surgeries, this book fulfills the need for a practical, hands-on manual for surgeons. Pilon fractures remain a challenge for traumatologists. To apply the distractor laterally, a 4 mm Schanz pin is placed transversely from lateral to medial into the talar neck, through the surgical incision. The AO/OTA classification is one of the most frequently used systems for classifying proximal tibial fractures or proximal tibial end segment fractures. These include the presence of articular comminution and impaction. Appreciate the consistent Y pattern creating 3 main articular fragments. There may be some benefits to this technique with possibly less swelling and stiffness. Tibial Plateau Fracture Pre-Surgery Information The following is what can be expected prior to tibial plateau fracture surgery: Examinations: X-rays will be taken and a CT scan or MRI may.Surgical Approaches to the Proximal Tibia 08:38. Most tibial pilon fractures are best approached anteriorly. This fracture typically happens after a fall or a motor vehicle accident. Integrity and condition of the soft tissue envelope, 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. One of the first stages in this injury is rupture of the anterior tibiofibular ligament (or anterior syndesmosis). The major three articular fragments anterolateral, posterolateral and medial are shown. Make a straight incision lateral to the patella. It is imperative that the extensor retinaculum is also repaired to prevent bowstringing of the extensor tendons. The fracture can be stabilized with lag screws, an antiglide plate, or combinations thereof. Definitive plate fixation consisted of an anterolateral non-locking plate combined with a medial non-locking plate. This webinar will familiarize the viewer with this technique and will review pertinent research and case examples. Tibial plafond fractures are uncommon, and are difficult to manage [1]. of high-energy tibial plafond fractures, Bone and colleagues reported their results using combined internal and external fixation techniques. 0. The break can range from a single crack in your bone to shattering into many pieces. Fractures of the distal tibial plafond are also termed pilon fractures to describe the high energy axial compression force of the tibia as it acts as a pestle, driving vertically into the talus. Obtain focused history and perform focused exam . In view of the fact that most pilon fractures usually occur as the result of violent trauma (i.e., motor vehicle accident), associated bodily injuries must be considered in the work-up of these patients. The injury-radiographs demonstrate tibial shortening. Open pilon fracture with extensive soft tissue injury and a severe crush component are graded as type 3. Like other fractures, they are divided into three groups subject to the severity and complexity of the respective injury 1: *applies for anterolateral/posterolateral/anteromedial/posteromedial/central simple metaphyseal or multifragmentary metaphyseal fractures with or without metadiaphyseal extension, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The quality of reduction with external fixation alone was suboptimal, leading to poor outcomes secondary to joint arthrosis. American volume. Weight-bearing radiographs are preferable to assess articular cartilage thickness. 2. Type 3 injuries portend the worst prognosis as a consequence of articular comminution and metaphyseal impaction. Pilon is a French term used to describe a fracture of the distal tibia usually characterized by high-energy traits, including dissociation of the articular surface from the tibia shaft. Other common complications seen following treatment of tibial pilon fractures are arthrofibrosis and posttraumatic arthritis. Unable to process the form. Check for errors and try again. Type 2 Tscherne injury describes advanced muscle contusion and deep, potentially contaminated abrasions. The most common fracture pattern occurs with the ankle in dorsiflexion (i.e., the foot on the brake pedal during a motor vehicle accident). Fibular stabilization and fixation (if needed and the soft tissues allow), Soft-tissue coverage (local or free flap). AO Davos Courses 2022. To expose the joint make a horizontal capsulotomy between the deep edge of the meniscus and the tibia. There is no muscle tissue to cushion or protect the bone if skin is injured. 1. Two small (2.5 mm) threaded pins or two K-wires are placed directly into the exposed anterior cancellous surface of the posterolateral fragment and used as joysticks to correct the dorsiflexion and posterior translation of the posterolateral fragment. Radiographs are critical for characterization of the bony injury and joint position and must include an ankle anteroposterior, mortise, and lateral view. . Return of skin wrinkles is a good sign of soft-tissue recovery. The distractor may need to be removed to allow plate placement. The rate of deep infection decreased with external fixation, however, at a cost. Lateral articular comminution can be approached through either an anteromedial or anterolateral approach. 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. Fractures of the tibial pilon (plafond) represent some of the most invalidating articular lesions. (2006) Mario Donati and the vertical mattress suture of the skin. Limited range of motion. World J Surg; 30(2):141-148).
