Bimalleolar (16%), trimalleolar (7.5%), and isolated medial malleolar fractures (about 6%) follow a similar pattern to US studies. With this type of injury, the other bone in the lower leg, the fibula, is frequently broken as well. The most common mechanism is usually a fall (about 38% to 80%) and the most common fracture is of the lateral malleolus (70%). Stress fractures. Tillaux Fracture. radiolucent table and C-arm from contralateral side. (2015) ... A bimalleolar equivalent or maisonneuve injury with associated disruption of the syndesmosis and Fibula length is often ensured with comparative contralateral intra-operative images. a bimalleolar, supination external rotation injury, with a Weber B fibular fracture). A better understanding of both bimalleolar and trimalleolar ankle fractures can be gained by noting the specific bones damaged in these injuries. The ankle joint is where the bones of the leg (the tibia and fibula) meet with the bones on the hindfoot (talus) to form a joint that allows the foot to bend up and down. In addition, the term “bimalleolar fracture” is ambiguous because it can be used for fractures of any two of the three malleoli. Bimalleolar fractures of ankle is to evaluate the functional outcome and results obtained after different modalities of treatment. The mechanism of injury in this case is obvi- ously diVerent from that in our case. They are seen in the context of medial malleolar and infrasyndesmotic, transsyndesmotic or suprasyndesmotic fibular injuries. About two thirds of ankle fractures are isolated malleolar fractures; one fourth are bimalleolar, and the remaining 5% to 10% are trimalleolar ( Egol et al. If the fracture is not out of place or is a very low fracture with very small pieces, it can be treated without surgery. Bimalleolar fracture causes. mechanism of the talar body fractures. In 80% of ankle fractures the foot is in supination position while, in 20% of fractures the foot is in pronation position. The mechanism of injury for an ankle fracture is classically a twisting or rotational injury, and thus most are not typically regarded as high energy fractures (Davidovitch and Egol 2010). Ankle fractures are becoming increasingly common, and they account for approximately 10% of all fractures. Twisting with the Bimalleolar fractures and Trimalleolar fractures occur after a wide range of personal injury accidents including slip and falls, trip and falls, motorcycle accidents, car accidents, and many others. fractures. Discussion The case reported here seems to be very rare. Inversion injuries occur more often. Conclusion: Medial malleolar fractures can be divided into four fracture types: transverse fractures, which correlated with supination-external rotation injuries; oblique fractures, which correlated with pronation-external rotation injuries; vertical fractures, which correlated with supination-adduction injuries; and comminuted fractures, which did not correlate with a particular type of injury. Medial malleolar fractures often occur with a fracture of the fibula (lateral malleolus), a fracture of the back of the tibia (posterior malleolus), or with an injury to the ankle ligaments. The medical term for a broken ankle is a bimalleolar fracture, or a break at the lower parts of the tibia and fibula. We propose that this fracture is the third stage of Lauge-Hansen's mechanism of injury … The second stage is a vertical fracture of the medial malleolus, which may also involve some impaction of the joint surface on the medial aspect of the tibial plafond (4) (Fig. Syndesmotic injury was positively correlated with transverse fractures … The Lauge-Hansen classification is not simple, however, and most people stick to the anatomical and Weber classifications. 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. Fibular alignment (length and rotation) has to be maintained for lateral stability of the ankle. Ankle fractures are very common injuries to the ankle which generally occur due to a twisting mechanism. The accepted mechanism of injury is an external rotation force applied to the ankle with the foot in either supination or pronation. A bimalleolar fracture Involves the lateral malleolus and the medial malleolus. Classification . patient supine with feet at end of bed and bump under hip for neutral limb rotation. Methods: SER type 4 ankle fractures are considered unstable and are generally treated with surgical fixation. ... Lateral Injury: classic posterosuperior anteroinferior fibula fracture Medial Injury: medial malleolar fracture &*/or deltoid ligament injury . Medial exploration is necessary only if one is unable to reduce the mortise. The Pott fracture has inappropriately evolved into a term to describe a bimalleolar fracture.Pott originally described a fracture of the distal fibula, 2–3 inches proximal to the ankle joint, with an associated tear of the deltoid ligaments and lateral displacement of the talus. The therapist needs to take into consideration multiple variables including: mechanism of injury, fracture type, fixation method, , bone and tissue quality, and fixation stability surgeon specific philosophy/preferences. Bimalleolar fractures are often caused by motor vehicle accidents, falls, and twisting the ankle. Posterior process fracture; the talar body or tibial pilon. These are not used in isolation, and the most thorough way of describing an injury is to combine all three (e.g. As a result, the orthopedic management is varied and can range from nonoperative casting to staged surgery with a primary focus on damage control… Bimalleolar ankle fracture is caused by twisting with multiple force mechanisms, or supination injury. Ankle fractures 1. 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 ]. On the lateral view the distal fibular fracture fragments displaced by 5mm posteriorly. Post reduction xray shows satisfactory alignment of the ankle mortise. Fractures in 223 patients (65%) were surgically managed, and ankle fractures were the most common type of fracture to be surgically treated. Ankle fractures range from simple injuries of a single bone to complex ones involving multiple bones and ligaments. A fall from a height was the main single injury mechanism in all fracture groups, especially for the talus, calcaneus, and midfoot fractures . They looked retrospectively at the radiographs of … Pattern 1) Lateral fibular buttress (infrasyndesmotic, adduction mechanism of injury) The medial malleolus has been pushed off by the adducting talus. Diagnosis The patient has a bimalleolar fracture-dislocation. Diagnosis is made with orthogonal radiographs of the ankle. [10]. Internal fixation of the bimalleolar fracture with lateral plate and screw fixation of the distal fibular and screws stabilizing the medial malleolus fracture. Long-term recovery depends on the severity of the injury, ability to realign the fracture fragments, and compliance with rehabilitation efforts. Review the latest information on visitor policies, safety procedures, vaccines and more in the COVID-19 Resource Center . Sultan A(1), Shabir M(1), Mehmood M(1), Manzoor QW(1). Complications: Common complications associated with surgery for treatment of a fibula fracture are related to the incision and the underlying hardware. 11 Because there is very little soft tissue between the skin and the bone, wound healing problems, infection, and painful hardware are by far the most common surgical complications. 18. ... and other bone and/or ligamentous injury, respectively. Although this classification system is straightforward, it oversimplifies ankle injuries and has little relevance to mechanism of injury or treatment. Triplane Fracture • 6-8% of Pediatric Distal Tibia Fractures • Mechanism of Injury = External Rotation w/ Supinated Foot • Average Age at Injury is 1 to 1.5 Years Younger than Children with Tillaux Fractures • Fracture Lines Occur in the Transverse, Coronal and Sagittal Planes Ankle fractures are among the most common skeletal injuries; selection of an optimal management method depends on ankle stability. Ankle fractures can occur from many types of trauma including slips on the ice, a fall down … Although this classification system is straightforward, it oversimplifies ankle injuries and has little relevance to mechanism of injury or treatment. Having an ankle fracture occur in two different locations, combined with a torn ligament, makes this injury serious. The medial malleolar fracture is displaced by approximately 9mm inferiorly. The ankle joint is susceptible to injury and one common typeof injury is called an ankle fracture. Downey et al. Here, we report a case of tarso-metatarsal (lisfranc) dislocation with bimalleolar fracture with syndesmotic injury. Keywords: Bimalleolar ankle fractures, functional outcome, Olerud and molander scoring Introduction Bimalleolar ankle fractures are most common injuries treated by orthopaedic surgeons [1-3]. Impacted proximal humerus The patient sustained a bimalleolar ankle fracture while sledding. During evaluation of ankle fractures, the mechanism of injury (eg, eversion, inversion, dorsiflexion, plantar flexion), associated injuries (eg, vascular, ligamentous, capsular), the need for immobilization (eg, application of a splint), and the need for referral to a specialist for further treatment or evaluation (eg, additional immobilization, surgery, or rehabilitation) are all important components of care. Approach. Suspect a bimalleolar fracture on the basis of the mechanism of injury, visible deformity, and significant pain. ANKLE INJURIES praveen reddy p 2. Author information: (1)Government Hospital for Bone and Joint Surgery, Barzulla, Srinagar, Kashmir. Half of the patients had bimalleolar fracture and 5 (15.6%) of them had intraarticular injury which was the highest number. Patients with a bimalleolar fracture were more likely to return to sports than those with unimalleolar fractures. Occasionally, they involve the shaft of the fibula as well. Posterior Malleolus Fracture (tibia only): This is a rare injury in isolation. direct approach to lateral and … The injury is named after Jacques Lisfranc de St. Martin (2 April 1790–13 May 1847), a French surgeon and gynecologist who noticed this fracture pattern amongst cavalry men, in 1815, after the War of the Sixth Coalition. Bimalleolar Fracture; Trimallelolar Fracture; ... Fractures do have a pattern that helps the physician identify the mechanism of injury that assists the doctor in treating the problem. mentioned that forced pronation with external rotation can also result in bimalleolar ankle injuries6. The therapist needs to take into consideration multiple variables including: mechanism of injury, fracture type, fixation method, , bone and tissue quality, and fixation stability surgeon specific philosophy/preferences. Fracture Assessment and Decision Making. Lateral process fracture; has been attributed to a rotatory element in the complex 5. Trimalleolar fracture is a fracture of the lateral malleolus, medial malleolus, and posterior aspect of the distal tibial articular surface. Crush fracture. The Lauge-Hansen classification associates specific fracture patterns with the mechanism of injury.4 It is defined by two words, the first relating to the position of the foot and the second relating to the direction of force applied relative to the tibia: Supination-external rotation (70%) Supination-adduction. pronation and external rotation or abduction. The medial malleolus fracture 4. Mechanism of Injury / Pathological Process [edit | edit source] A Pott’s fracture is a fracture affecting one or both of the malleoli. The therapist also needs to consider patient These injuries span a spectrum from simple closed fractures to complex open injuries. Bimalleolar fractures commonly occur due to falls, car accidents, and sports-related activities. Ankle Injuries Type III — The ligaments tear all the way through, rip into two separate parts, there will be considerable pain, swelling, tenderness and discoloration. Bimalleolar Fracture Equivalent or Deltoid ligament Tear with Fibular Fracture. 2.Define the specific articular pathology associated with SA and PAB fractures. This also requires open reduction and fixation of fibular fractures. This does not deal with fracture pattern, mechanism of injury or the ligamentous injuries. Bimalleolar ankle fractures or fractures where there is talar shift or syndesmotic injury should be referred for specialist orthopaedic care. Because both the medial and lateral malleolus is torn, a Pott’s fracture is often referred to as a bimalleolar ankle fracture. If necessary, the syndesmosis can be reduced open, with screw fixation placed parallel to the joint. Bimalleolar and Trimalleolar Ankle Fractures. Bimalleolar ankle fracture is usually caused by twisting injury with multiple force mechanisms [4-6]. Clinical Presentation. The therapist also needs to consider patient Usually, this means that the fibula is broken along with injury to the medial ligaments, making the ankle unstable. In addition, the term “bimalleolar fracture” is ambiguous because it can be used for fractures of any two of the three malleoli. A person who sustained bimalleolar and trimalleolar fractures in a traumatic accident, trucking collision, car accident, slip and fall, or motorcycle accident is entitled to compensation for their injury as well as any complication that occurs after the injury. Also called functional bimalleolar fracture. Most ankle fractures are complex injuries that are difficult to manage. Distinguish between isolated bimalleolar fracture and bimalleolar fracture–dislocation. Ankle mortise. Mechanism of injury of Nursemaid's elbow. Surgical anatomy of anklejoint Saddle shaped joint Three bone joint – tibia, fibula and talus Tibia - tibial plafond and medial malleolus Fibula – lateral malleolus Large surface of talar dome anteriorly and laterally 3. Bimalleolar ankle fracture: This second-most common type involves breaks of both the lateral malleolus and of the medial malleolus, the knobby bump on the inside of the ankle (in the lower portion of the tibia). 3.List the 3 common posterior malleolar fracture patterns. Bimalleolar ankle fractures occur when both the tibia and fibular are broken, and involve injuries to the inner (medial malleolus) and outer (lateral malleolus) sides of the ankle, and typically require surgery, as both the ankle joint becomes unstable and is otherwise susceptible to ankle arthritis, if left untreated. The most common mechanism that cuts this ligament is foot eversion or external rotation force. Mechanism Timing Soft-tissue injury Bone quality Comorbidities Associated Injuries PHYSICAL EXAM Skin Nerves Vasculature Pain Deformity . Pronation-external rotation The lateral malleolus of the fibula and the medial malleolus of the tibia form a mortise in which the talus sits. ... Open Reduction Internal Fixation of a Bimalleolar Ankle Fracture With Syndesmotic Injury. The mechanism and movement of the talus suggests tearing and disruption of the ... complex for bimalleolar equivalent fracture types after fixation . You may be given antibiotics to prevent infection, especially if there is an external wound. Most medial fractures require surgery even in minimal displaced fractures (in which there is 2 millimeters or more of separation of the fracture fragments). Stable fractures (eg, isolated lateral malleolar) generally are managed nonsurgically; unstable fractures (eg, bimalleolar, bimalleolar equivalent) usually are managed with open reduction and internal fixation. Because most Maisonneuve fractures involve complete syndesmotic disruption, operative treatment is usually indicated. A pilon fracture is a type of break that occurs at the bottom of the tibia (shinbone) and involves the weight-bearing surface of the ankle joint. Simultaneous Symmetrical Bilateral Bimalleolar Open Fracture with Ankle Dislocation by Indirect Injury - Case Study. Posterior Malleolar Fracture These ... on the basis of the mechanism of injury and fracture pattern. This classification is based on the level of the fracture of the fibula. The term “ankle fracture” typically refers to a fracture of the lateral malleolus, the medial malleolus, or both. Ankle Fractures Rena L. Stewart Jason A. Lowe INTRODUCTION Ankle fractures are among the most common musculoskeletal injuries. 2010c ). Unfortunately the distal tibiofibular syndesmosis is too wide (lack of tibiofibular overlap) and this ankle will probably be unstable unless a syndesmotic screw is added. The ankle joint is where the bones of the leg (the tibia and fibula) meet with the bones on the hindfoot (talus) to form a joint that allows the foot to bend up and down. If the fracture is displaced, the only option is open reduction and internal fixation. 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. A "bimalleolar equivalent" fracture means that in addition to one of the malleoli being fractured, the ligaments on the inside (medial) side of the ankle are injured. Type 1-Unimalleolar, Type 2-Bimalleolar and Type 3-Trimalleolar. Bimalleolar ankle fracture is called Pott’s fracture. Understanding the mechanism of injury is essential for anatomical reduction and fixation. ... Femur fracture Bimalleolar ankle fractures Unreducible or unstable fractures Fractures in patient with multiple comorbid conditions. Shear fracture (coronal, sagittal or horizontal); of the dome of talus and usually produces comminution of 3. • Also known as Broken Ankle, Ankle Fracture and malleolar fracture. 5). What fractures do not require surgery, just supportive treatment? Stage 1 The first injury will occur on the medial side, which is under maximum tension due to the pronation. Frontal. It is precerts rare that they are pathological. Common Types of Tibia and Fibula FracturesProximal Tibial Fractures. These fractures occur in the knee end of the tibia and are also called tibial plateau fractures. ...Tibial Shaft Fractures. This type of fracture takes place in the middle, or shaft (diaphysis), of the tibia. ...Distal Tibial Fractures. These fractures occur at the ankle end of the tibia. ...
