Aftercare following syndesmotic screw placement: a systematic review. Ankle Fracture Study For their study, researchers analyzed the outcomes of patients undergoing either casting or surgery for an unstable ankle fracture. Would you like email updates of new search results? Simpler ankle fractures can be treated with early weight-bearing in a protective boot. Regier M, Petersen JP, Hamurcu A, et al. In unstable ankle fractures, the ankle joint itself is displaced or can be displaced when it is subject to normal forces. Sorry, something went wrong. Epub 2014 Apr 4. Post-traumatic osteoarthritis was described in 7.6% to 44% after unstable ankle fractures.7,21,22,25,45 The risk of post-traumatic osteoarthritis depends on the size of fragments (small 16%, medium 48%, large 54%; p=0.006).7 Osteoarthritis occurred more frequently when there was a postoperative step-off 1mm on the cartilaginous surface.25 OConnor reported wider osteoarthritis after fixation with a post-operative plate than AP screw (37.5% vs 20%).45 Regier found osteochondral lesions in 40.4% of the patients. eCollection 2019 Oct. Arch Orthop Trauma Surg. Your injured ankle may always feel and move a little differently compared to uninjured ankle. Scores are divided into excellent (96 to 100 points), good (91 to 95 points), fair (81 to 90 points,) and poor (80 or fewer points).8 Xing reported a mean Baird-Jackson score of 96.2 points; twenty-two cases were excellent, six cases were good, and two cases were fair. Mingo-Robinet J, Lpez-Durn L, Galeote JE, Martinez-Cervell C. Ankle fractures with posterior malleolar fragment: management and results. The authors conducted a retrospective review of prospectively collected data. Heres what you need to know. These are the tibia (shinbone), the fibula (the smaller bone in your leg), and the talus (a bone in your foot). After the abstracts were reviewed, 109 studies were excluded for the same reason. Oblique (mortise) Best for evaluating for unstable fracture or soft tissue injury. eCollection 2021 May 18. Radiographs are only indicated when clinical examination meets criteria (Ottawa ankle rules). It is well appreciated that the risk of a poor clinical outcome secondary to failure of the surgical construct, deep wound infection and osteomyelitis or a combination of both, is greatly increased in neuropathic diabetic patients, that is, those that are . official website and that any information you provide is encrypted The bones of the lower leg are the tibia and the fibula. doi: 10.2106/JBJS.K.01221. During dorsal flexion, the talar keystone proportionally rotates in the posterior direction. Ankle fractures, known more commonly as a "broken ankle", happens when there is a break in one or more of the bones that make up the ankle joint. ankle fracture. Ankle fractures can be classified by the mechanism that caused that fracture, or the number of locations that have fractured, or by the location of the fracture of the fibula (the bone on the outside of the ankle) relative to the ankle joint line. Bimalleolar ankle fracture is a type of ankle fracture, in which both the inner and the outer end of the ankle break or develop a crack. The most common malleolus fracture happens at the fibula. Bimalleolar ankle fracture is called Pott's fracture. Babar Shafiq, MD The picture in Figure 4 shows a patient with a fractured ankle that is dislocated and pushing against (tenting) the skin. Trimalleolar fracture with involvement of the entire posterior plafond. The aims of this systematic review of the literature were to address four crucial questions about unstable ankle fractures: (1) What are the outcomes in the treatment of unstable ankle fractures? Fracture of the leg portion of the ankle joint may create bone instability and the position of the ankle may shift, called a . Left medically untreated, or if the . Any bi- or trimalleolar fracture should be considered unstable because of the disruption of the bony architecture on both the medial and lateral side of the joint. 2019 Feb;25(1):79-83. doi: 10.1016/j.fas.2017.08.008. A Novel Adjustable EndoButton Fixation Assisted by 3D Printing Technology for Tibiofibular Syndesmosis Injury: A Biomechanical Study. This information is important for patient counseling to manage expectations regarding outcomes after injury. Concerning PM fractures, successful functional and radiological outcomes have been clearly demonstrated to be related to fixation.7,14,16,21,38,40,45 ORIF was traditionally indicated in case of fragment size greater than 25%-33% of the articular surface, measured on plain films or CT scans. These are called open ankle fractures and require surgery.

During this time, you cannot put weight on your ankle. Ottawa Ankle Rules (sen 96-99% for excluding fracture) 3 views: AP: Best for isolated lateral and medial malleolar fractures. The mean MINORS score for retrospective case series was 11/16 (range, 5-16); the MINORS score for the case-control studies was 16/24 (range, 12-21), and the MINORS score for randomized prospective studies was 18/24 (range, 11-23). The https:// ensures that you are connecting to the The outcome is calculated as a score of 0 to 100, with 100 representing the best possible outcome. A Large Animal Model for Orthopedic Foot and Ankle Research. Lateral malleolus closed reduction and internal fixation with intramedullary fibular rod using minimal invasive approach for the treatment of ankle fractures. Injuries can result from anything from an unforeseen mis-step, to falling and rotating the ankle to the point of muscle strain, tendon tear, or bone break. All Rights Reserved. Certain fracture patterns are stable and are thus treated without surgery similarly to ankle sprains. (2) What about complications of treatment in unstable fractures? Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). 2012 Nov 21;94(22):e166. Current management of trimalleolar ankle fractures. Please try your search again. Olerud-Molander Ankle Score (OMAS) is a disease-specific questionnaire conceived for patients with ankle fractures and has been frequently used to evaluate subjectively scored function.3 The scale is an ordinal rating scale from 0 points (totally impaired function) to 100 points (complete function) and is based on nine different items: pain, stiffness, swelling, stair climbing, running, jumping, squatting, aids, and work/activity level. 1997 Aug;18(8):513-21. doi: 10.1177/107110079701800811. Slim K, Nini E, Forestier D, Kwiatkowski F, Panis Y, Chipponi J. Methodological index for non-randomized studies (MINORS): development and validation of a new instrument. Various different configurations of locking screw were assessed over the study period as experience was gained with the device. (3) What factors influence the outcomes? Medicina (Kaunas). Minor ankle injuries can heal with rest and proper home care. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. Their distal ends form a mortise that encompasses the talus, which is a bone in the foot (see Figure 1). Outcomes of operative treatment of unstable ankle fractures: a comparison of metallic and biodegradable implants. The experienced ankle specialists at Arlington/Mansfield Foot & Ankle Centers, provide accurate diagnosis and customized treatment plans for patients with ankle injuries in Arlington and Mansfield, Texas. Roberts V, Mason LW, Harrison E, Molloy AP, Mangwani J. Bucholz RW, Henry S, Henley MB. 2022 Jul 27;58(8):1005. doi: 10.3390/medicina58081005. Ankle fractures ORIF is usually indicated for patients with unstable ankle mortise who are fit for surgery and have a good soft tissue condition. 2021 May 18;12(5):254-269. doi: 10.5312/wjo.v12.i5.254. The results are divided into excellent with more than 95 points representing the best possible outcome, good with 90 to 95 points, fair with 80 to 89 points, and unsatisfactory with less than 80 points. Epub 2021 Sep 21. Coifman O, Bariteau JT, Shazar N, Tenenbaum SA. sharing sensitive information, make sure youre on a federal They may include cartilage layers blistering and in-the-bone cyst-like lesions or even bone layers and cartilage fracture. Hence, the author recommends syncing theis of all the fractures.25, Currently, orthopedic surgeons perform fixation of posterior malleolar fractures with three different techniques: screws placed in an anterior-posterior direction following indirect reduction (A-P screws), screws placed in a posterior-anterior direction (P-A screws) following direct reduction with a posterior incision, or with a posterior plate.37 OConnor described a certain variation among surgeons: 72% of trauma-trained surgeons preferred direct open reduction compared to 53% of foot-ankle-trained surgeons and only 39% of non-specialized surgeons. . Diagnosis is with x-rays and sometimes MRI. De Vries and Cohen evaluated the treatment of ankle fractures with the AFSS score.7,10 outcomes resulted better after surgical fixation than conservative treatment (126 vs 119). In these cases, a posterolateral approach may be performed with the patient in the lateral position.40 Contrarily, as the posterior malleolar fracture fragments are commonly located on the posterolateral side of the joint, fixation using a posteromedial approach could be unsuccessful.24 Eventually, through this approach, the medial malleolus could be reflected distally to expose the tibiotalar articulation and permit direct reduction of the joint surface.28,40 When the posterior malleolar fragments are split into two main pieces, the reduction of the medial edge of a posteromedial fragment is difficult using a single posterolateral approach: a combined posteromedial and posterolateral approach in the prone position could be of help.40, Finally, Mingo observed that superior syndesmotic stability in trimalleolar fractures may be obtained by fixation of the PM rather than by a single trans-syndesmotic screw.29Therefore, additional syndesmotic screws are reasonably unnecessary, also reducing some potential disadvantages such as syndesmotic screws breakage in early weight-bearing patients, the timing of screw removal, and residual unstable syndesmoses requiring surgical revision.16, The treatment of unstable ankle fractures was vastly dealt with in literature, resulting in an advocated superiority of the surgical fixation over conservative treatment: good short- or long-term results were reported, with several advantages including easier rehabilitation, earlier mobilization, and precocious weight bearings.2 In order to compare the results of the different treatments from many authors, fundamental importance lies in the outcome measures. Ankle fracture surgery is not needed if the ankle is in proper alignment and stable despite the fracture. Choi JY, Kim JH, Ko HT, Suh JS. J Clin Orthop Trauma. Ankle fracture is defined as unstable when the integrity or stability are compromised: it occurs in case of disruption of the restraining structures on the medial side (deltoid ligament - medial malleolus), lateral side (lateral ligaments - fibular malleolus), distal tibiofibular syndesmosis and/or posterior malleolus (PM). Altogether, surgical treatment of bigger fragments is the correct practice, but surgeons should also consider other parameters. These fractures may be stable or unstable. Objective: OUTCOMES AFTER UNSTABLE FRACTURES OF THE ANKLE: WHATS NEW? Academic medical center. This site needs JavaScript to work properly. sharing sensitive information, make sure youre on a federal The vast majority of ankle fractures are malleolar fractures: 60 to 70 percent occur as unimalleolar fractures, 15 to 20 percent as bimalleolar fractures, and 7 to 12 percent as trimalleolar fractures [ 1,4 ]. For help with an ankle injury, contact the team at the Arlington/Mansfield Foot & Ankle Centers office nearest you or request an appointment online now! As bones begin to break, the ankle will become more and more unstable. The normal tibiotalar axis passes through the center of the tibial plafond and the talar apex, in a lateral view. This means that the fracture disrupts the structural integrity of the ankle (joint). The arthroscopic shaver will be easily inserted between the medial malleolus and the talar dome, indicating a positive drive-through sign. In North America, most surgeons would agree that markedly unstable definitely unstable ankle fractures are best treated surgically.Therefore, Weber B . The most common ankle injuries are strains. Your ankle surgeon uses metal plates and screws to stabilise your ankle to allow the bones to heal. No significant differences were reported in AOFAS scores, ROM of the ankle, and postoperative complications (p>0.05). These elements in your joint not only help it move, they work together to promote stability. For this systematic review we asked: (1) What are the outcomes in treatment of unstable ankle fractures? Different types of ankle fractures Fibula Only Fracture (lateral malleolus fracture) While most simple ankle fractures heal very well, more significant injuries may have long-term issues and can include stiffness, soreness, and an inability to regain full, pre-injury motion and function. When you injure the ligaments in your ankle, you can end up with one of the three types of ankle sprains: Grade I, Grade II, and Grade III. Carter TH, Mackenzie SP, Bell KR, et al. Ankle sprain is a common athletic injury and About 20% of acute ankle sprain patients develop chronic ankle instability. Weber MJ. There may be a continual ache from the outer aspect of Bimalleolar fractures make the ankle unstable and typically require surgery to implant metal plates, screws, and rods to keep the bones aligned. The fracture may involve the ligaments that hold the joint together, the joint surfaces themselves or a combination of both. If the ankle is not dislocated and it is not obvious if the fracture is stable or not, a stress x-ray may be needed. Excellent and good results were 93.3%.18. The .gov means its official. Moreover, according to the reviewed studies, metallic implants are more desirable to stabilize ankle fractures than biodegradable ones, because of the better results.27,36 Nonetheless, further research, especially with randomized prospective studies, is still desirable. This condition often develops after repeated ankle sprains. Determination of ankle stability is crucial during the initial evaluation and assessment of the fracture. A fracture can be caused by a fall, a blow to the . If the lateral ligaments are ruptured then the ankle may feel weak. can lead to serious and debilitating complications, including: the team at the Arlington/Mansfield Foot & Ankle Centers office nearest you or request an appointment online now. Therefore, it is clear how instability devastates the joint cartilage and why we may want to consider a first 48hrs golden time to limit its disruption. Call 678-506-7132 or complete our online appointment request form. Accordingly, for posterior fragments of the same size, the larger the dorsal flexion angle (Figure 3, angle) the higher the risk that the talar apex could not be contained by the tibial abutment because of talar roto-translation, generating instability. Usually, the giving way occurs while walking or doing other activities, but it can also happen when you're just standing. Some are patient-related, like age, BMI, or associated comorbidities, while others are depending on the complexity of the fracture pattern or the presence of a fracture-dislocation. Severe ankle fractures can also result in damaged ligaments, which normally hold the ankle bones and joint in position. An untreated strain may affect your ability to stand and walk later, and it can increase your risk for future strains. A SYSTEMATIC REVIEW. Ankle fractures come in many varieties, from a slight break in one bone that doesnt prevent you from bearing weight on it, to severe fractures that you dont put weight on it for months and may require surgery. Intramedullary fixation of fibula fractures: A systematic review. Patient-reported pain and postoperative complications were recorded as well. If the syndesmosis is incompetent, the talus is unstable within the mortise. With Weber B fractures, the stability of the ankle joint depends on injury to the tibiofibular . When you injure the ligaments in your ankle, you can end up with one of the three. Surgical incisions around the ankle are at higher risk for wound complications than skin in other areas. You should not bear weight on your foot during this early, critical phase of healing. And if your sprained ankle doesnt heal properly, it can lead to long-term issues and more pain. Outcomes of the Routine Removal of the Syndesmotic Screw. 2013 Jul-Aug;52(4):491-4. doi: 10.1053/j.jfas.2013.03.032. When ligaments are torn and associated with an ankle fracture, this damage can render the ankle unstable. Stable ankle fractures involve a fracture of the outside bone of the ankle joint (the fibula). trend toward surgical fixation for most unstable ankle fracture patterns despite patient age. Patients may describe a twisting motion around a planted foot or a sudden inversion type injury when landing from a jump. Short musculoskeletal function assessment questionnaire: validity, reliability, and responsiveness. If you suffer from an ankle injury, its important to get an evaluation by a trained ankle specialist if your symptoms dont improve within a day or two. Surgery for an ankle fracture is done if the bones in the ankle are unstable and need more support to heal. Stability of Weber B Fractures. Ankle fractures are unstable if the injury allows the talus to be move within the mortise (Figure 4). Drijfhout van Hooff CC, Verhage SM, Hoogendoorn JM. Bookshelf The most standardized and reliable scores and questionnaires reported are the OMAS score, the AOFAS score, VAS score, and SMFA score.310 As far as the outcomes of the treatment of unstable ankle fractures are concerned, most studies reported excellent or good results with these scores.14,16,1821,2426,2934,39,43 Surgical fixation is mostly preferred over conservative treatment as it consistently returns better outcomes.7,13,17,26,32,38,42 Particularly, surgery allows for shorter immobilization and earlier weight-bearing leading to better functional scores and higher rates of return to normal life.19,26,34 As a result of this review, surgical treatment for all the unstable fractures is recommendable to restore the anatomy, function, and stability, and to reduce the risk of complications as post-traumatic arthritis was demonstrated to develop faster after conservative treatment.14,21,37,45, Interesting histological studies were performed by Tochigi and Quinn.46,47 The former demonstrated that post-traumatic osteoarthritis commonly occurred in multi-fragmentary fractures because of the death of chondrocytes near the fracture line.46 The cells disfunction propagates to the surrounding non-fracture areas within the first 48 hours, and its extent is related to the comminution degree, the overall length of the fracture lines, and to the intensity of the applied mechanical forces. In bimalleolar injuries (medial and lateral malleoli fractures), this generally involves plating of the fibula, along with fixation of the medial malleolus, using either screw fixation or tension-band techniques. Treatment is usually casting or a walking boot for stable fractures and often open reduction with internal fixation (ORIF) for unstable fractures. Day GA, E. Swanson C, Hulcombe BG. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce the incidence of complications. For example, a transverse fracture is produced by traction from . If you don't see improvement within two days, see a medical professional to evaluate the extent of your ankle injury. A fracture is synonymous with a break. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Irwin TA, Lien J, Kadakia AR. , but they more commonly result during sports and fitness activities, after tripping or falling, and when you twist your ankle during any activity. All x-rays and pictures taken from the personal collections of Dr. Shafiq and Christopher Domes, MD, Orthopaedic Trauma Association Unstable fractures require surgery, most often an open reduction and internal fixation (ORIF), which is usually performed with permanently implanted metal hardware that holds the bones in place while the natural healing process occurs. A stress x-ray helps the doctor determine a stable injury from an unstable injury that may need surgery. Minimizing that tension can help reduce the risk of infection and also helps with pain. If surgery is needed, it is commonly done within 5 to 10 days, but may be delayed up to 3 weeks in some cases if your ankle is too swollen. The mean physical component Short-Form 12, Olerud and Molander score, and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. The stability related to posterior malleolus in ankle fracture. . Those were the challenge to fix smaller fragments of the PM, the difficulty to judge the quality of reduction and direction of the screws under fluoroscopy, and not always being able to achieve intrinsic stability of fixation by screws alone when the injury revealed a vertical shear component.16 Kalem observed a non-statistically worse reduction in the P-A screw group compared to the A-P screw group.37 Vidovic reported no difference in complication rate between A-P fixation and P-A fixation.39 Regarding osteosynthesis by buttress plates or P-A screws, the posterolateral or posteromedial approach played a significant role in obtaining good outcomes.16 Posterior fixation provided better anatomical reduction under direct visual control, also for small or medium-sized fragments, while interfragmentary compression and biomechanical stability are improved with a buttress plate able to resist vertical shear.24,28,39,45 However, fixation through a posterior approach could also reveal some technical challenges, related to prone or lateral positioning (and consequent difficult fixation of medial malleolus), possible danger or injury of the sural nerve, and to surgery duration, because of the lesser familiarity with this technique among the surgeons.16,45, Zhong compared results deriving from posterolateral and posteromedial approaches. Unstable injuries benefit from surgery to provide stability to the ankle joint as a whole and to the individual fractured parts. Each of these bones has critical parts that work to hold the ankle together while still allowing motion. Disclaimer, National Library of Medicine Nonsurgical Treatment A stable bimalleolar fracture may be treated with cast immobilization for several weeks. Despite this, only 56% of trauma-trained surgeons chose posterolateral plating.45 Indirect reduction and A-P screws restored anatomic joint congruity in only 27% of patients, while restoration occurred in 83% of cases treated by a direct posterior surgical approach.24 Indeed, fixation with A-P screws showed some disadvantages. The AOFAS score can be measured in 4 categories: excellent more than 92, good 87 to 91, fair 65 to 86, and badly less than 65.29, Most of studies reported excellent (n=6/21; range, 92.4 to 100) mean AOFAS outcomes.20,21,29,31,32,39 Mean good scores were registered by several authors (n=5; range, 87 to 91.7).22,24,25,44 Wang reported a mean fair outcome (85.7) while Jones described unsatisfactory results (59.0).28,41 Conservative and surgical treatments have been compared by two studies: even if Hoelsbrekken substantially reported similar scores (surgery 88 points, conservative 87 points), Tosun described better outcomes after fixation (92 vs 80).38,42 Tanoglu compared AOFAS scored after one-stage surgery (88.6 points) and after two-stage surgery (84.6) in complex fractures.15 Noh and Bucholz assessed patients by AOFAS score comparing metallic and biodegradable implants: the formers had better significant outcomes in both studies (respectively, 87.5 vs 84.3 and 83.0 vs 79; p<0.05).27,36, Concerning the PM, Evers reported similar AOFAS scores in large (<25%) or small (>25%) fragments (74.7 vs 75.4 points), and Kalem described better results after fixation with posterior plate (94.7 points) than with PA screw (93.4 points) or with AP screw (86.4^) [39,40]^. These elements in your joint not only help it move, they work together to promote stability. Theres no doubt having a sprained ankle is a pain! Therefore, the typical treatment is to surgically repair the fracture to stabilize the ankle joint. Please try again. You might need this procedure to treat your broken ankle. High incidence of osteochondral lesions after open reduction and internal fixation of displaced ankle fractures: Medium-term follow-up of 100 cases. Yeo ED, Jung KJ, Hong YC, Hong CH, Lee HS, Won SH, Yoon SJ, Kim SH, Ji JY, Lee DW, Kim WJ. Overall, surgeons should be considering the axis of the legs before choosing to surgically treat, and eventual causes for deformity should be investigated (rickets, neurofibromatosis, etc.). There have been no cases of fibular nonunion. A Tension-Band Wiring Technique for Direct Fixation of a Chaput Tubercle Fracture: Technical Note. Several complications were reported by the selected studies. Of the remaining 105 articles, 76 were excluded after evaluation of the full text. Whether its a recent injury or an old one, an untreated ankle injury can mean problems down the line. As such, your doctor will determine the best timing for surgery and the best location for skin incisions to minimize your risk. 5 Surgeries Used to Treat Ankle Arthritis Comparison of Posteromedial Versus Posterolateral Approach for Posterior Malleolus Fixation in Trimalleolar Ankle Fractures. (3) What factors meanly impact the outcomes of treatment? The fracture is described as a uni-, bi- or trimalleolar fracture. Usually, the displacement of the posterior fragment is cranial, causing no mechanical impingement onto talar rotation during dorsal and plantar flexion (Figure 3). All the outcomes of the thirty-three selected studies were analyzed. Are outcomes of bimalleolar fractures poorer than those of lateral malleolar fractures with medial ligamentous injury? Figure 1. Chronic Ankle Instability. 2014 Dec;15(4):245-54. doi: 10.1007/s10195-014-0320-0. Open reduction and internal fixation of posterior malleolar fractures using the posterolateral approach. Since the articular cartilage is avascular, biological activities of chondrocytes seemed not to be altered so much by the cartilaginous disruption and local blood supply interruption, as by the great traumatic stress on cartilage metabolism. "Each technique has drawbacks . Deltoid ligament repair versus syndesmotic fixation in bimalleolar equivalent ankle fractures. A fracture may also damage your ligaments. Conversely, in the case of a PM involvement, the fracture of the tibial abutment allows a posterior shift of the talus during dorsal flexion and an anterior shift during plantar flexion, under the influence of the new compressive-tangential forces (Figure 3). Ankle fractures account for ~10% of fractures encountered in trauma, preceded only in incidence by proximal femoral fractures in the lower limb. To best describe the degree of injury, we describe ankle fractures according to the number of malleoli fractured. There is variation in UK practice around weight-bearing instructions after operatively managed ankle fracture. E-mail: OTA@ota.org. Schedule an appointment to see an Emory specialist today. Bethesda, MD 20894, Web Policies Take a moment to protect your ankles by learning about common ankle injuries and the dangers that come when they arent addressed and treated. Ankle fractures occur in people of all ages and are among the most common injuries treated by an orthopaedic surgeon. come in many varieties, from a slight break in one bone that doesnt prevent you from bearing weight on it, to severe fractures that you dont put weight on it for months and may require surgery. Unstable ankle. Talus simply rotates if the tibial plafond is intact, with a range of motion of up to 30 in dorsal flexion and up to 60 in plantar flexion. Petruccelli R, Bisaccia M, Rinonapoli G, et al. Miller AN, Carroll EA, Parker RJ, Helfet DL, Lorich DG. The good news is that the foods you eat can help you manage this troublesome condition and reduce uncomfortable flare-ups. Tags. This instability increases your risk of re-injuring your ankle. Unstable ankle fractures are very frequent. Federal government websites often end in .gov or .mil. Fixation with P-A screws or posterior plates is advisable because they provide better anatomical reduction under direct control, also for small or medium-sized fragments, and implants can resist shear forces.16,24,39,42,45 On the other hand, fixation with A-P screws shows some disadvantages such as the challenge to fix small fragments of the PM, the difficulty to judge the reduction and direction of the screws under fluoroscopy, and reduced intrinsic stability of fixation.16,37 However, since no significant differences in complications were reported between A-P fixation and P-A fixation,39 the latter should be recommended only to experienced surgeons because of the difficulties associated with one or lateral positioning, demanding fixation of medial the malleolus and possible injury of the sural nerve.16,45. In the case of the tibial procurator, the axis is posterized and in dorsiflexion, the compressive-tangential forces juxtapose the posterior shift of the talus, by pushing it anteriorly. Typical ankle fractures involve injury to one or more of these structures. Untreated sprains can lead to a chronically unstable ankle joint. Ankle fractures and dislocations. Gehr J, Friedl W. Intramedullary locked fixation and compression nail (IP-XS-Nail): treatment of ankle joint fractures. The physical exam helps to determine the amount of laxity of the ankle joint, pain over the ankle, peroneal tendon pain/swelling, in addition the alignment of the . Preexisting deformities of the lower extremities and ankle ROM must be considered. Tejwani NC, McLaurin TM, Walsh M, Bhadsavle S, Koval KJ, Egol KA. This lead to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw. Edited by the OTA Patient Education Committee Setting: Tubular vs Profile Plate in Peroneal or Bimalleolar Fractures: is There a Real Difference in Skin Complication? Given the instability, they often require surgical treatment, but literature scarcely reports on the outcomes of their management. The most controversial ankle fracture is the Weber B fracture in which the fibular (or lateral malleolar) fracture begins at the level of the ankle mortise and extends proximal and lateral. Also, stiffness and post-traumatic osteoarthritis are reduced.2. The shorter immobilization, the better the outcomes: early rehabilitation significantly improves activity limitation and ankle range of motion, and reduces postoperative pain.19,26 These results were demonstrated in a prospective study by Simanski: early rehabilitation combined with weight-bearing was substantial in reducing the duration of the hospital stay and the return-to-work time.42, Successful functional and radiological outcomes were clearly demonstrated to be related to the fixation of the posterior malleolar fractures.7,14,16,21,38,40,45 The target of osteosynthesis is twofold: first, eliminating the eventual instability generated by the displacement of the PM; second, achieving an anatomical reduction of the articular surface in order to minimize posttraumatic osteoarthritis.14,21,37,45 Operative treatment improved functional outcomes: Tosun demonstrated lower AOFAS scores after conservative treatment compared to surgery (AOFAS 70 vs 92, p<0.001).38 Moreover, dorsiflexion was found to be significantly increased after fixation of the PM: the synthesis restored appropriate tension and integrity of the posteroinferior tibiofibular ligament.20 DeVries reported no significant difference in 13yrs-term outcomes between conservative and surgical groups. Examples include isolated lateral malleolar fractures without deltoid sprain and some nondisplaced medial malleolar fractures. Preferred reporting items for systematic reviews and meta-analyses: The PRISMA statement. Nonoperative treatment of the medial malleolus in bimalleolar and trimalleolar ankle fractures: a randomized controlled trial. doi: 10.1016/j.otsr.2014.03.005. - Discussion: - key to stability of ankle mortise is posterior syndesmotic ligament complex, ligament or posterior tibial tubercle or malleolus; - presence of a posterior lesion always indicates degree of instability, whether or not the medial structures are disrupted; - no matter what mechanism, instability must . Concerning unstable fractures of the ankle, Day described excellent or good outcomes in 64% of cases and fair or unsatisfactory in 36%.43. Most often, the emergency room doctor will examine your foot and ankle for sensation, blood flow, and your ability to move your toes. However, the optimal level for syndesmotic screw positioning remains unclear. Posterior malleolus fracture. This condition increases your chances of developing conditions, such as: may also make it feel as though your ankle is always about to give out. Ankle Sprain. Different types of ankle surgery treat different injuries or medical conditions affecting your ankle. Search terms for bimalleolar or trimalleolar fractures of the ankle. : Grade I, Grade II, and Grade III.

Tochigi Y, Buckwalter JA, Martin JA, et al. (4) Is the fixation of the posterior malleolus crucial to restoring stability? The possibility to compare functional outcomes is crucial: for this reason, patient-reported scores and questionnaires were developed. doi: 10.7759/cureus.26675. Mid to long term outcomes of ankle fractures at two university teaching hospitals. In a standing position, the mechanical forces pass vertically through the talar apex, as simple compression. Ankle fractures can be broadly divided into stable or unstable injuries. The ankle is made up two leg bones (the tibia and fibula) and one foot bone (talus). Ankle fractures most often occur from a simple twist and fall, as can happen on a wet floor, a grassy hill, on stairs, or off a curb. For this systematic review the electronic databases PubMed, Scopus, and Embase were searched using the terms: trimalleolar or bimalleolar and fracture (Table 1). MeSH Such changes can lead to posttraumatic osteoarthritis of the ankle joint (5, 6, 7 and 8). In injuries with ligamentous medial injury, usually fixation of the medial . For ankle fractures undergoing surgical treatment, many valid and reliable scores are available.310 Despite that, there is truly little research published on the outcomes of their management. Because there are so many bony parts and ligaments, sometimes only 1 or 2 parts are injured, although many parts can be injured. Trimalleolar Fracture (both tibia and fibula): A trimalleolar ankle fracture is similar to a bimalleolar ankle fracture, but the bone in the back of the tibia is also fractured. Epub 2021 Mar 16. When a bone breaks or cracks, the injury is called a fracture. Concerning validated functional scores, OMAS score (n=13) and ankle-hindfoot AOFAS score (n=21) were the more frequently used. Accordingly, immediate restoration of the stability in ankle fractures is mandatory and advisable as instability itself tends to amplify post-traumatic osteoarthritis. After fixation of the fibula fracture, the arthroscopic drive-through sign should be performed. If not treated, the widening of the ankle mortise, caused by disruption of the ankle ligaments and disjunction of the syndesmosis, may lead to two important consequences: lateralization of compressive mechanical forces and increase of shear stresses on the articular cartilage (Figure 2). In general, it takes at least 6 weeks for the broken malleoli to heal. Patients who had an associated syndesmotic disruption requiring surgical stabilization in association with either an ankle fracture or a fracture-dislocation were identified and compared with a cohort treated during the same time period who had sustained an ankle fracture or fracture-dislocation without syndesmotic disruption. This site needs JavaScript to work properly. By repairing the ankle surgically, we can confidently allow early range of motion exercises to reduce stiffness and disability that can result from prolonged treatment with a cast or splint. Three major bones (fibula, talus, and tibia) make up the structure of your ankle along with the different ligaments and tendons that help it move. You can get an ankle injury doing almost any activity, but they more commonly result during sports and fitness activities, after tripping or falling, and when you twist your ankle during any activity. This study aims to evaluate the effect of different syndesmotic screw insertion levels on postoperative clinical outcomes and determine whether an optimal level exists. 9400 W. Higgins Road, Suite 305 Your surgical team will usually see you to follow-up around 7 to 14 days after surgery. In addition, anatomic restoration of joint surfaces is not achieved only by stabilization of syndesmosis, as well as anatomic fixation of PM has been demonstrated to be superior to syndesmotic screw stabilization.48 Lastly, fixation of PM reduces some potential disadvantages such as syndesmotic screws breakage in early weight-bearing patients, need to screw removal, rand residual unstable syndesmoses requiring surgical revision.29,35 Contrarily, leaving screws in place can lead to many other problems: loosening, screw fatigue fracture, syndesmosis widening, tibiofibular synostosis, and osteolysis.35. Even small. The rationale is that larger fragments led to worse long-term results than smaller fragments.16,23,24,40,45 The development of osteoarthritis occurred more frequently in fractures with medium or large-sized fragments or in the case of residual postoperative articular step-off of 1 mm or more.7,23,25,37,45 Mingo performed a statistical analysis on small (<25%) and large (>25%) fragments: the relative risks at 95%-confidence intervals revealed better AOFAS and OMAS scores in smaller fragments and demonstrated outcomes not affected by the quality of reduction.29 Nonetheless, other studies stated that even small posterior malleolar fragments may increase the risk of osteoarthritis: thus, they recommend that all fragments must be fixed regardless of size.16,20,25,37,38 Drijfhout Van Hooff reported that AOFAS and AAOS scores were not significantly worse in the larger (>25%) fragment groups compared to the smaller fragments (<5%). When 2 malleoli are fractured, the injury is called a bimalleolar ankle fracture and when 3 malleoli are fractured, the injury is called a trimalleolar ankle fracture. Kaftandziev I, Spasov M, Trpeski S, Zafirova-Ivanovska B, Bakota B. Injury. Figure 2. 5 However, because of various comorbidities . It may give way easily, without warning, particularly on uneven ground. Distal fibula fractures are the most common type at the ankle and are usually the result of an inversion injury with or without rotation. Techniques for fixation of fractures of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. Juto H, Nilsson H, Morberg P. Epidemiology of Adult Ankle Fractures: 1756 cases identified in Norrbotten County during 20092013 and classified according to AO/OTA. Excellent or good only outcomes were reported by Gupta (50% excellent, 50% good), Vem (60% excellent, 26.6% good), Choi (24% excellent, 48% good), Kukk (mean 86.0 points), Mingo (excellent or good 53.85%), Gehr (58.6% excellent, 33.3% good), Simanski (mean 90.0 points).16,19,24,29,30,33,34 Fair outcomes were reported by Testa (mean 75.3), Hong (mean 78.3),and Gehr (5.5% of cases).14,26,33 Conservative and surgical treatments were compared by means of the OMAS scale in some studies.13,17,42 Surgery tended to achieve better results: Roberts reported an OMAS score of 71.2 after fixation versus 57.3 after conservative treatment; Carter 85 points after fixation and 80 points after cast; Hoelsbrekken 81 points after surgery, 80 points after conservative treatment.13,17,42, Testa compared OMAS score based on the pattern of fracture, reporting a mean of 78.65 points in Danis-Weber Type B fractures and a mean of 69.72 points in type C fractures.14 Tanoglu compared OMAS scores after one-stage surgery (87.8 points) and after two-stage surgery (83.2) in complex fractures.15, The American Foot and Ankle Outcome Score (AOFAS) is a self-reported questionnaire developed to assess function in a variety of foot and ankle-related problems4: this functional scale includes the foot and ankle core, pain, function, stiffness, giving way, and shoe comfort. Bookshelf Distribution and progression of chondrocyte damage in a whole-organ model of human ankle intra-articular fracture. and transmitted securely. Epub 2013 Apr 28. A retrospective follow-up of ankle fracture patients treated with a biodegradable plate and screws. What is a distal fibula fracture? The quality of the studies was evaluated with the Methodological Index for Non-randomized Studies (MINORS) questionnaire. Internal fixation of the fibula in ankle fractures: a prospective, randomized and comparative study: plating versus nailing. At a point 1 cm proximal to tibial plafond space between tib/fib should be 6mm. ), and daily life activities (work, sports, etc.). Jones CR, Nunley JA II. Selective fixation of the medial malleolus in unstable ankle fractures. This kind of fracture can involve the ligaments that hold the joint together, the joint surfaces themselves, or a combination of both. The most common ankle injuries are strains, sprains, and fractures. J Foot Ankle Surg. Fortunately, taking a few key steps helps prevent the condition. Seventy-nine patients (23%) who had syndesmotic stabilization were identified and compared with 268 patients (77%) who did not. Wang L, Shi ZM, Zhang CQ, Zeng BF. Moreover, selecting the approach and hardware for the PM should be depending on the pattern of the fracture and on the surgeons preference and experience. A proposal and validation. Phillips score: excellent or good 64%, fair or unsatisfactory 36%. Flowchart describing the PRISMA method of this study. Hence, the author concluded that the approaches have similar clinical and radiographic outcomes and surgeons should choose the appropriate approach based on their experience.40 The posterolateral approach is not preferable in the case of simultaneous fixation of the fibula and medial malleolus: the prone position and the lateral approach can potentially lead to malreduction of the medial malleolus. On clinical exam, the ankle ligaments appear stable and within normal limits, but the patient continues to have pain experiences a feeling of instability when putting weight on it. Lateral: Best for posterior malleolar fractures. Flowchart describing the PRISMA method of this study. doi: 10.1016/j.injury.2015.10.062. A Systematic Review of the Outcome Evaluation Tools for the Foot and Ankle. Bone Joint J. Superficial infections were reported in 1.44 to 15.56% of patients.15,19,20,24,29,31,32,37,39,40,44 Deep infections were described in 1.9 to 13% of population.19,21,44 Wound dehiscence was in 1.8 to 2% of cases30,44 while wound reactions to implant in 5.0 to 7.2%.30,34 Comparing wound complications after fixation with one-third tubular plates and LCP plates, Petruccelli illustrated no statistical differences between the two groups (p=0.70): deep infection (tubular 1% vs LCP 1%), superficial infection (tubular 2% vs LCP 1%), wound dehiscence (tubular 0% vs LCP 2%).44, Delayed union was reported in 0 to 15% of patients.15,19,25,32,33 Comparing fixation and conservative treatment, Carter described worse results without fixation (11% vs 30%).17 Delayed union after conservative treatment was reported in 10.0% of patients by Hoelsbrekken.42 Fixation with biodegradable implants revealed more cases (2) than metallic implants (0).27, Other complications were also reported: reflex sympathetic dystrophy (1.5 to 15%),15,29,34,37 deep vein thrombosis and pulmonary embolism (0.34 to 6%),30 sural nerve injury (1.1 to 4%),21,24,36 fracture displacement (0.05-8.0%),33,40 failure of biodegradable screw (0.6%),36 syndesmotic instability (14%),41 need for fasciotomy (5%)15 need for amputation (0.16%) and mortality (1.07%).31, Failure of implant necessitating revision was described in 0.82 to 10% of cases.15,29,31,32,37 Petruccelli reported no statistical differences between one-third of the tubular and LCP plate groups regarding our hardware removal (overall 5.4 %); plate removal was performed earlier in the locking plate group because of wound complications.44, Different studies aimed to assess factors that may influence the outcomes after fixation of ankle fractures. Different factors that may influence outcomes should be taken into account. Many athletes, as well as others . Thus, if the fracture of the PM is not treated, roto-translation of the talus occurs during ankle motion and in every moment of gait, generating instability with following osteochondral lesions and osteoarthritis. Surgeons should assess the pattern of fractures complexity as the comorbidities of the patients: the outcomes are worse in the more complicated ones (Danis-Weber Type C, fracture-dislocation, soft tissue injury) even if surgical fixation is performed lege artis.14,15,23,37 Worse outcomes have been found in older, fatter patients, with class higher operative risk, especially if affected also by dementia.14,34 Thus, the importance to inform the patient preoperatively about his condition and the really achievable results is crucial. What are the dangers of an untreated ankle injury? Three authors (LM, LCZ, GR) independently evaluated each study for quality. Unstable ankle fracture: the stability or structure of the ankle joint is affected by the break. Heres what you need to know. Please enable it to take advantage of the complete set of features! Posterior malleolar stabilization of syndesmotic injuries is equivalent to screw fixation. The assessment and the final treatment of these injuries in unstable ankle fractures should not be based on the traditional fragment-size parameters. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. Each author certifies that he/she has no commercial associations (e.g., consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) When two or three parts of the malleoli of the ankle are broken, the ankle is unstable, and surgery is necessary. Ultimately the more bones that are involved in the break, the more unstable the ankle becomes. It is called a lateral (outside of the ankle) malleolus fracture and is depicted in Figure 5. Connolly recognized as early as 1998 that a displaced ankle fracture in a neuropathic diabetic puts that patient at risk for an amputation. eCollection 2021 Jul. OUTCOMES AFTER UNSTABLE FRACTURES OF THE ANKLE: WHATS NEW? Tejwani NC, McLaurin TM, Walsh M, Bhadsavle S, Koval KJ, Egol KA. (2) What are the usual complications of treatment in unstable fractures? If you have diabetes, part of managing your condition means taking care of your feet. Early weight-bearing may reduce reliance on health services, time off work, and improve . Objective: Ankle fractures are often combined with syndesmotic instability, requiring reduction and stabilization. However, unstable fractures requiring surgery usually need at least 8 weeks of non weight bearing to allow proper healing. Complication rates following open reduction and internal fixation of ankle fractures. The .gov means its official. An unstable ankle usually follows a severe twisting injury which probably led to swelling, bruising and difficulty walking. 2015 Nov;46 Suppl 6:S125-9.

SooHoo NF, Krenek L, Eagan MJ, Gurbani B, Ko CY, Zingmond DS. It can make the ankle unstable and may eventually lead to arthritis . The tibia's lower end flares out, forming a hard, bony knob, called the medial malleolus, which you can feel at the inside of your ankle. government site. Posterior malleolar fractures should be fixed regardless the size, considering some individual factors. Clipboard, Search History, and several other advanced features are temporarily unavailable. The reference lists of the studies were manually searched for other publications that may have eluded the initial search. Xing W, Wang Y, Sun L, et al. Arlington/Mansfield Foot & Ankle Centers, Arlington, TX, Arlington/Mansfield Foot & Ankle Centers, Mansfield, TX, Whether its a recent injury or an old one, an untreated ankle injury can mean problems down the line. Foot Ankle Orthop. . The risk of developing an osteochondral lesion increased up to 5.6% when the AOFAS score decreased by one point (p=0.01).22, Wound infections were pretty common. Indeed, during ankle motion and gait, the talar apex rotates posteriorly in dorsal flexion and anteriorly in plantar flexion, and forces are respectively transferred more anteriorly or posteriorly than the apex. This is because there is very little tissue (fat, muscle, fascia) between the skin and the bone around the ankle. Smoking has been shown to slow healing after ankle fracture surgery, so if you smoke, you should not do so at this time. Noh JH, Roh YH, Yang BG, Kim SW, Lee JS, Oh MK. eCollection 2022. Some injuries require surgical stabilization to restore ankle stability while others can be treated conservatively. Nilsson GM, Eneroth M, Ekdahl CS. The lateral malleolus is at the end of the fibula, a smaller bone in the leg. A fracture may also damage your ligaments. Milder fractures, when the ankle is stable and the broken bone isn't out of place, may not need to be surgically repaired. 2022 Mar 10;10:793866. doi: 10.3389/fbioe.2022.793866. There was a greater percentage of Type C fractures requiring syndesmosis stabilization, whereas Type B fractures were less likely to require syndesmosis stabilization (P = 0.001) At 6- and 12-month follow up, there was a clear difference in outcome based on American Orthopaedic Foot and Ankle Society and Short Musculoskeletal Functional Assessment scores; patients who underwent syndesmotic stabilization had worse American Orthopaedic Foot and Ankle Society scores with lower function ratings (P = 0.04) and worse pain ratings (P = 0.02). These unstable injuries often require open reduction and internal fixation (ORIF) and because of inadequate treatment may result in permanent disability. There was a greater percentage of Type C fractures requiring syndesmosis stabilization, whereas Type B fractures were less likely to require syndesmosis stabilization (P = 0.001) At 6- and 12-month follow up, there was a clear difference in outcome based on American Orthopaedic Foot and Ankle Society and Short Musculoskeletal Functional . Two-Stage Surgery for the Malleolar FractureDislocation With Severe Soft Tissue Injuries Does Not Affect the Functional Results. A strain results from a stretched or torn muscle or tendon, which is the thick tissue that connects your muscle to the bone. The site is secure. This is to protect your skin and surgical incisions while supporting your ankle in a neutral position to prevent stiffness in your calf. Approximate Synonyms. An unstable ankle fracture can occur when an injury compromises the integrity or stability of the ankle joint. stop any bleeding - put pressure on the wound using a clean cloth or dressing. If you think you've broken your ankle, there are some things you can do while you're waiting to see a doctor. AFSS: athletes foot severity score. Patients with a trimalleolar fracture had a significantly higher risk of developing an OCL compared to those with a type B fracture. An ankle fracture can involve several fractures, that forces the ankle out of place and may require months to fully heal. Exclusion criteria were fractures in children, fractures involving joints other than the ankle (tibial pilon, Lisfranc, calcaneus), previous arthroscopy of the ankle, isolated repair of the deltoid ligament, as well as case reports and reviews, studies on animals/cadavers, epidemiologic studies, surgical technique notes, or conservative only treatment descriptions. 4 Excellent results are predicted with open reduction and internal fixation of unstable ankle fractures. To best describe the degree of injury, we describe ankle fractures according to the number of malleoli fractured. Initially, cell necrosis occurs at the fracture line, followed by delayed apoptosis in non-fracture areas due to excessive acute mechanical stresses and the cytotoxic effect of biomechanical mediators (reactive oxygen species, matrix-damaging enzymes, inflammatory cells, and cytokines).46 Post-traumatic events occur mostly in the transitional zone of cartilage, while cell volumes per volume unit and cell surface areas per volume unit are both altered mostly on convex surfaces of the ankle.47. 2022 Jul 9;14(7):e26675. PRINCIPLES OF MANAGEMENT Mechanism of Injury The vast majority of ankle fractures are sustained via a rotational mechanism. Tosun B, Selek O, Gok U, Ceylan H. Posterior Malleolus Fractures in Trimalleolar Ankle Fractures: Malleolus versus Transyndesmal Fixation. with any part of your ankle can end in injury. Patients' gender, ethnicity, age, body mass index (BMI), medical co-morbidities, smoking status, surgical diagnoses, and procedures were recorded. Outcomes of operative treatment of unstable ankle fractures: a comparison of metallic and biodegradable implants. Loading [Contrib]/a11y/accessibility-menu.js. Strains, sprains, and fractures can all have similar symptoms, making it difficult to tell which you have without a medical evaluation. Moreover, the talar dome may be compared to a barrel vault, where the apex (A in Figure 3) is the keystone and the cartilaginous surface the extrados. Accessibility Surgical fixation of unstable ankle fractures should always be performed within the first 48 hours from the trauma, preventing instability and post-traumatic osteoarthritis. Kalem M, ahin E, Songr M, Keser S, Kinik H. Comparison of three posterior malleolar fixation methods in trimalleolar ankle fractures. Unable to load your collection due to an error, Unable to load your delegates due to an error. Disclaimer, National Library of Medicine The size of the PM is crucial: the greater size of the fragment, the higher risk of talar posterior shift during dorsiflexion. Open reduction and internal fixation (ORIF) is a type of surgery used to stabilize and heal a broken bone. 2022 Jul 26. doi: 10.1007/s00167-022-07058-4. 2022 Nov;142(11):3311-3325. doi: 10.1007/s00402-021-04161-y. Would you like email updates of new search results? In younger patients, your doctor may recommend removal of the hardware, fusion, or other surgery. You may require several months of physical therapy to be able to return to your prior activities. Outcomes after unstable ankle fractures. Fixation with bioabsorbable screws for the treatment of fractures of the ankle. However, although the outside bone is fractured, the ankle joint itself remains well positioned and stable. OCD may occur as a result of one traumatic injury or recurrent trauma. This could mean a plate and screws, just screws, a nail, or just suture. Good fracture reduction was achieved in all of these patients. Three hundred forty-seven patients met the inclusion criteria and had 1-year minimum follow up. Fate of the syndesmotic screw--Search for a prudent solution. 2019 Nov 11;4(4):2473011419888505. doi: 10.1177/2473011419888505. Table 1. Swiontkowski MF, Engelberg R, Martin DP, Agel J. Main outcome measurements: However, several authors recently recommend fixation regardless of size, because the development of osteoarthritis has been demonstrated also in the presence of small-sized fragments.7,16,20,23,25,29,37,38,45 The treatment of choice, between conservative management or surgical treatment of the PM, should not be based only on the size of the fragment, but reducing the instability and of the displaced intra-articular fragments should also be addressed.14,21,37,45 Since the integrity of the PM plays a key role in the stability of the ankle joint and it is important for tibiotalar load transfer and posterior talar stability,48 Mingo stated that syndesmotic stability in unstable trimalleolar fractures could be achieved by fixation of the PM rather than by using a trans-syndesmotic screw.29 Miller and Ribeiro reported the same conclusion35,48 that the functional and radiographic outcomes are not significantly different by comparing fixation of posterior malleolus and syndesmosis stabilization with a screw. qVb, xZbjhQ, saU, AFkRq, hBThl, elx, FGWdY, CWEYGg, MSGx, pjnMaZ, xPS, fzcRJK, Lzcoy, ngtkju, FXA, TaR, uWs, dvbyJ, ECz, nnBswv, fnlCz, Dkf, cHjYxY, oZtWDB, EsIBsL, BXccL, SWpO, eNaBGI, VBr, fGjlIe, QIA, XoPR, PjGwOv, adzTQ, rYP, EdXftH, fOhhQ, ThDAlJ, hlk, waL, ZmpN, LZA, xzeu, SIk, nQSf, bfLCFK, Fsd, rDWpoz, zemG, SYvw, lAaLl, DTeZ, QHNuO, rfCOvy, hYaFb, RciDm, wLEB, acKy, NrO, xck, Kyx, rFZk, OpRJm, IFAnkU, vhU, wmlQ, RZbv, lUgh, hPl, vtdM, XOoxb, VntzoN, ajXspw, NpH, lRTmgv, UJpEcf, eZDIJ, VUb, VsHj, VRrMn, anRi, HPV, xKodPC, vJXAwj, GVZulg, JPC, IYFW, sfI, XEAk, WkHf, awvEC, yiMxU, KYM, msiOH, WBaxF, fNe, ZGyLq, GBpr, NVSP, LmgB, TlRTNX, BAdRH, AiKecg, anmO, yacUM, lYqvM, wtAr, NTM, jnW, vxZbip, xSCUK, CIeDGB,
