This could occurwhen a snowboarder stops suddenly, for example. Authors Olivier Wijers 1 , Jelle J Posthuma 1 , Mathijs B J De Haas 2 , Jens A Halm 3 , Tim Schepers 4 Affiliations Appl Radiol. Epidemiology Incidence peroneal tendon tears seen in 23-77% of all cases of lateral ankle . 1. A fracture of the anterior process of the calcaneus can usually be seen on a plain x-ray lateral view of the foot (Figure 3). The fracture may sometimes be difficult to identify on radiographs and CT may be necessary to identify the fracture line. Lateral process fracture (~10%) Dorsiflexion with axial loading. Navicular stress fracture. Once the fracture is united, progressive weight bearing and gait rehabilitation is started. CT is indicated when clinical suspicion is high but radiographs are negative. Talus fractures (other than neck) are rare fractures of the talus that comprise of talar body fractures, lateral process fractures, posterior process fractures, and talar head fractures. A fracture should be suspected when there is soft tissue swelling inferior to the lateral malleolus. Purpose of the study: Fracture of lateral process of the talus is an uncommon injury, fracture of the posteromedial tubercle of the talus is quite rare, and association of the two lesions is not reported previously. Its inferolateral surface comprises a portion of the posterior facet of the talocalcaneal joint, while its superolateral surface articulates with the lateral malleolus. It is often 3-6 months or more before a full recovery is achieved. if radiographs are equivocal or only suggestive and clinical suspicion Diagnosis is often missed and confused with a lateral ankle sprain. MRI studies can help identify the size of peroneal tendon tear and identify concomitant injuries to nearby structures. A lateral process fracture of the talus is a fracture of the lower bone of the ankle on the outside (lateral) aspect of this bone.

Treatment may be nonoperative or operative depending on patient activity demands, chronicity of injury, and peroneal instability. A talar avulsion fracture occurs when a small part of your talus bone pulls away from the rest of the bone where it's attached to a ligament or tendon. (OBQ20.15) Figure A is the radiograph of a 55-year-old female who is a poorly-controlled diabetic with neuropathy and peripheral vascular disease (PVD) that underwent ankle open reduction internal fixation (ORIF) two years ago at an outside facility. If the size of the screw head is less than a third of the fragment, then successful fixation may be achieved. A plain x-ray may be diagnostic, but coronal CT scans are often necessary for a complete definition of the injury. Early range of motion of the ankle and subtalar joint is advised.Weight bearing should be restricted for 6 weeks with follow-up occurring at 2 and 6 weeks.Radiography at 6 weeks should confirm healing. 1% (43/2985) 3. lateral talar process fracture. Lateral Talar process fractures. Measure the depth for screw length.A cannulated partially threaded screw will be used for fixation. with a thorough radiographic evaluation, including CT ankle evaluation Lateral talar process fracture. It will be removed when fixation is complete.If possible, two screws would be optimal, but often not possible. Failure to Use image intensification to make certain that reduction is anatomic and that the fixation has been appropriately inserted to maintain stability and articular congruity. reserved for fragments >1 cm or fragment displacement 2 mm. 2022 Lineage Medical, Inc. Often they will be unable to weight bear. Fracture of the lateral process of the talus. 5. diagnose and properly treat a fracture of the lateral process of the Unable to process the form. An ankle avulsion fracture is a bone chip caused by a ligament or tendon that tears away a part of the bone. 94% (2807/2985) 4. 2. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 15 Figure 15: J Ultrasound Med. After surgery apply a posterior splint with the foot in neutral position. Safe surgical dislocation with a trochanteric flip osteotomy has been shown to be a reliable technique that provides excellent exposure for treating femoral-head fractures with minimal complications. 1% (35/2985) 2. WebClavicle FX - Midshaft Clavicle FX - Distal Scapula FX A tibial plafond fracture (also known as a pilon fracture) is a fracture of the distal end of the tibia, most commonly associated with comminution, intra-articular extension, and significant soft tissue injury. "Lateral process of the talus fractures occur commonly in snowboarders following a twisting injury while the foot is strapped to the board. are an elevated index of suspicion in the proper clinical presentation lateral process articulates with posterior facet of calcaneus lateral malleolus of fibula posterior process consist of medial and lateral tubercles separated by groove for FHL Navicular bone Sustenaculum tali Blood supply talar neck supplied by three sources posterior tibial artery via artery of tarsal canal (dominant supply) HAWKINS LG. 2013;17 (04): 416-28. (Ribbans, 2005) Epidemiology: It accounts for 25% to 50% of all broken bones and is most commonly seen in older females and young males. Moving the ankle may increase the pain, and in some cases may cause a cracking sound. Orthobullets. Diagnosis Mechanism of the injury This fracture is often confused with an ankle sprain. Mosby. Smaller fragments It may be an isolated fracture or occur as a component of more complex ankle fractures. Semin Musculoskelet Radiol. Many lateral talar process fractures are displaced or potentially unstable enough to require surgical fixation. Talus fractures can be classified by how much the pieces of bone have moved out of their normal position. Commonly used techniques for immobilizing a joint. San Francisco CA 94123, Did you know our resouces can be found in. Conventional radiographic evaluation of the ankle showed a subtle 1. Connect with peers, learn from experts. It may be possible to see the fracture on a plain x-ray view of the ankle; however, these fractures can be quite subtle on plain x-rays and may be missed. 269 Chestnut St. #271 AO teaching video: Talar fractures: reduction and screw fixation. 2003;22 (6): 635-40. fractures have been graded by a three point scale 4 grade 1: uncomplicated fracture involving both articular surfaces grade 2: comminuted fracture grade 2 fractures may be further subdivided into 5 2a: <2 mm displacement of fracture fragments 2b: >2 mm displacement of fracture fragments grade 3: cortical avulsion fracture MRI Potential complications of surgery include general complications such as: Complications that are specific to surgery for a lateral talus process include: Previously Edited byVinod Panchbhavi, MD, FootEducation LLC snowboarding puts them at particular risk for this inversion-dorsiexion Lower extremity equivalent of galeazzi fracture. It is important to see your doctor as soon as the accident takes place to prevent more damage.. subtalar joint; this type may be treated conservatively or surgically, ISBN:0323072437. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. On examination, patients with a lateral process fracture of the talus will have tenderness, swelling and bruising over the outside of the ankle, towards the front and outer border of the foot. Anterior Process Calcaneus fractures occur from an inversion injury to the ankle The bifurcate ligament pulls on the anterior aspect of the calcaneum resulting in a fragment of bone being pulled away Diagnosing the Anterior Process of the Calcaneum fracture X-ray and ultrasound examination can show an anterior process of the calcaneum fracture. Patients will have pain and swelling in the ankle, particularly over the outside aspect. Swelling and ecchymosis over the cuboid should raise suspicion of this injury and when other midfoot injuries are present , the cuboid articulations should be carefully inspected for subtle injury. Lateral ankle swelling, lateral talar process fracture. Dec 416, 2022, Revised proximal femur module is now online. If the fracture fragments were just cleaned out (debrided), then weight bearing can be started once the patient feels comfortable. Patients with lateral talar fractures will usually describe an acute injury where their foot rolls outwards and ankle gets jammed on the outside (lateral side). Similarly, if a symptomatic nonunion develops, the fragment should be resected.If the fracture is completely undisplaced, then immobilization and non-weightbearing is indicated. Diagnosis is made radiographically with foot radiographs but CT scan is often needed for full characterization of the fracture. injury. of a fracture remains. from the articular surface of the posterior talocalcaneal joint space to recognize and treat this entity early can result in signicant A broken wrist or distal radius fracture is an extremely common type of fracture . Talus Fracture (other than neck) . Copercini M, Bonvin F, Martinoli C et-al. Radiographics. Diagnosis is made with radiographs of the foot but frequently require CT scan for full characterization. Summary A lateral process fracture of the talus is a fracture of the lower bone of the ankle on the outside (lateral) aspect of this bone. three charges are placed as shown below determine the magnitude and direction Talus fractures (other than neck) are rare fractures of the talus that comprise of talar body fractures, lateral process fractures, posterior process fractures, and talar head fractures. However, this injury can often be quite subtle and can easily be missed. is a comminuted fracture of the lateral process. Frequently missed findings in acute ankle injury. Fracture of the lateral process of the talus (snowboarders fracture). Stress fractures. Essential to the diagnosis J Bone Joint Surg Am. Plantar fasciitis. treatment based accordingly. If the fracture is comminuted and reduction and fixation is not possible, then one should consider resection. The most common type of ATFL injury is pure ligamentous rupture followed by avulsion fracture from the tip of lateral malleolus [3]. Fractures of the Lateral Talar Process - Discussion: - two processes, lateral & posterior, project from body of talus; - either process may be fractured, either as isolated injury or assoc w/ other ankle or talar injuries; - it is frequently confused w/ an ankle sprain; - non union is a frequent complication of displaced lateral process frx; Citation, DOI & article data. Hawkins LG. It can be confirmed by a CT or an MRI, which will show the small fracture fragment (Figure 4). The injuring force through the lateral process of the talus is distributed throughout a wider area than in the adult and this may be one of the reasons for the intra-articular fractures being less severe in children. Cardiac MRI perfusion and viability imaging: Clinical value in cardiac care, SNMMI 2013 Image of the Year: Radium-223 PET-CT image showing response in breast cancer patients. Talar neck fractures are high energy injuries to the hindfoot that are associated with a high incidence of talus avascular necrosis. timing. This is an injury that will often take many months to reach its point of maximum improvement. 4. Type I is a simple fracture that extends lateral process articulates with posterior facet of calcaneus lateral malleolus of fibula posterior process consist of medial and lateral tubercles separated by groove for FHL Navicular bone Sustenaculum tali Blood supply talar neck supplied by three sources posterior tibial artery via artery of tarsal canal (dominant supply) Check for errors and try again. Talar neck fracture most common (~50%) Dorsiflexion with axial loading, snowboarders. They can be seen fairly easily on a CT scan or MRI,one of which isoften ordered if there are questions as to the nature of the injury. anterior process fracture with >25% involvement of calcaneocuboid joint. This threaded K-wire is then introduced into the middle of the fragment, once reduced, and advanced into the body of the talus. 1 Its functions include lateral stabilization of the ankle, weight bearing by means of its articulation with the bula, and subtalar motion. As many as 40-50% of fractures are missed on radiographs due to overlapping osseous structures 2. Fractures of the lateral process of the talus always involve the subtalar joint and depending on the size of the fragment may also involve the articulation between the lateral surface of the talus and the lateral malleolus. Mosby. This is often called the "snowboarder's fracture". acetabular fracture causes symptoms diagnosis treatment. Lateral process fractures occur when the ankle is forced out to the side and are commonly seen in snowboarders. She was noncompliant with her immediate postoperative weight-bearing instructions and went on to fixation failure. ISBN:B0040SYP2C. Once thex-rays demonstrate adequate healing, activities can be gradually increased. measured on lateral view. The chronic fracture may then require a subtalar fusion. (OBQ12.261) A 23-year-old healthy male was involved in a motor vehicle collision and sustained the injury seen in Figure A. Lateral talar process fracturesor snowboarder fractures are talusfractures that can mimic a lateral ankle sprain. In this case, it may be necessary to remove these bone fragments by cleaning out these fragments (debridement) of the ankle. Treatment and prognosis It indicates, "Click to perform a search". A second K-wire should be placed eccentrically, if possible, to provide rotational control of this small fragment of cortical bone.

Jibri Z, Mukherjee K, Kamath S et-al. Ultrasound may be useful for detection, but follow up CT or MRI is necessary to further evaluate the extent of the fracture and the amount of displacement of the fragments 3. Lateral Process Fracture of the Talus: A Case Series and Review of the Literature J Foot Ankle Surg. X-rays and or CT scans not only help us confirm the diagnosis but also help us learn more about the lateral process of the talus, the piece of bone that is broken off the parent bone, the talus. depending upon the severity of the injury.3. The type of treatment depends on the fracture grade 6: If symptomatic non-union occurs, debridement may be necessary. Talar body fractures are a subtype of talar fractures, subdivided into: talar dome osteochondral fracture. Failure to detect the fracture may lead to non-union,ankle instability, and accelerated osteoarthritis. A magnifying glass. Posterior process, medial or lateral tubercle very commonly misdiagnosed as ankle sprains. Lateral process talus fractures are commonly seen in snowboarders and are sometimes called "snowboarder fractures." Avulsion fractures. ATFL injuries can occur in three distinct forms; (i) rupture of the ligament as a pure soft tissue injury, an avulsion fracture at the ATFL's attachment to the either (ii) fibula or (iii) talus [2], [3]. . 6. This type of injury is produced by forced eversion of the foot. A T1-weighted sagittal image in a 61 year-old male with lateral hindfoot pain, demonstrating mild sclerosis at the lateral talar process (arrowhead) and adjacent calcaneus. 2020 Jan-Feb;59 (1):136-141. doi: 10.1053/j.jfas.2019.02.003. An ankle CT, ordered to There is usually direct tenderness to palpation over . Often misdiagnosed as a severe lateral ankle sprain, failure to Avulsion fractures or little chips off of the bone and really aren't a big deal but can hurt like hell. Lateral process fractures are best visualized on lateral projections. It is a break of the lateral malleolus, the knobby bump on the outside of the ankle (in. The healing potential of these fractures in higher energy injuries is of concern given the tenuous blood supply which is easily disrupted with fracture displacement. The os trigonum may be mistakenly identified as a fracture on plain radiograph. Long-arm cast immobilization for 1 week, followed by active mobilization. Bone -modifying agents, such as bisphosphonates and denosumab, are efficacious in preventing and delaying cancer >-related bone disease. This fracture is often quite small, or multifragmented.If the piece is one large fragment, then screw fixation is preferred. This fracture can mimic a lateral ankle sprain, yet the fracture is easily missed on plain radiographs of the ankle. fracture of the lateral process of the talus. The mechanism of injury is forced eversion with a loaded hindfoot. This can occur in activities such as snowboarding and has lead to this being called a snowboarders fracture. It is associated with pain and swelling. Cancer -induced bone disease results from the primary disease, or from therapies against the primary condition, causing bone fragility. Lee P, Hunter TB, Taljanovic M. Musculoskeletal colloquialisms: how did we come up with these names?. persistent symptomatology. Then drill the thread hole in the body of the talus. Radiopaedia.org, the wiki-based collaborative Radiology resource Talar body fracture (~20%) Hindfoot in either supination or pronation, high energy trauma. Arthrosis of the subtalar joint may occur if this injury is not accurately reduced and treated. Therefore try to insert a smaller screw to achieve rotational stability. Snowboarders talus fracture: Mechanism of injury. 2004;24 (4): 1009-27. K-wires alone may be used but present difficulty (migration) if used alone. 2013-12-01. A pott's fracture is a term used to describe a bimalleolar (medial and lateral malleoli) or trimalleolar (medial and lateral malleoli, and distal tibia) fracture. mal-union, or nonunion.5 These fractures have been classied into 3 types by Hawkins,3 with and young adult population whose growing participation in the sport of Type III is a chip fracture on the Lateral talar process fractures (LTPF) are rare, but account for 15% of ankle injuries in snowboarders, who reveal a 17-fold increased risk of sustaining such a fracture [ 3, 4 ]. ADVERTISEMENT: Supporters see fewer/no ads. Morrison WB, Sanders TG. We report a case of an associated fracture of posteromedial tubercle an lateral process of the talus. The direct lateral approach allows visualization of this fragment. (Letts, 1980) Talus fractures encompass fractures of the neck, body, medial or lateral process, as well as osteochondral fractures. Minimally displaced or stable fractures: This type of fracture is barely out of place. Typically, recovery time from surgery requires six to eight weeks of relative immobilization and non-weight bearing, if the fracture has been stabilized (fixed with screws). Prepared by Kevin P. Banks, MD, Department of Radiology, Brooke Army Medical Center, Fort Sam Houston, TX, and Justin Q. Ly, MD, Department of Radiology and Nuclear Medicine, Wilford Hall Medical Center, San Antonio, TX. Fracture of the lateral process of the talus. Mills HJ, Horne G. Fractures of the lateral process of the talus. It typically occurs when the foot is jammed suddenly, and the outside of the lower ankle bone (talus) is pushed heavily against the adjoining bone (fibula). Sonographic diagnosis of talar lateral process fracture. The lateral process of the talus is small and the posterior subtalar facet is parallel to the ground. If the piece is very small then resection may be a better option. Patient and methods: The mechanism of injury was forced ankle dorsiflexion and . should be excised while the larger component is reduced and xed anteroinferior portion of the lateral process that is limited to the Bone is commonly affected in cancer . Diagnosis is made radiographically with foot radiographs but CT scan is often needed for full characterization of the fracture. If the fracture is not displaced, it may be treated with immobilization in a boot or cast for 6-8 weeks, until the fracture has healed. Campbell's Operative Orthopaedics. Cantrell MW, Tarquinio TA. If surgery is indicated, the fracture area is opened up through an incision on the outside front of the ankle, and a screw or screws are placed into the fracture to stabilize it to a larger part of the talar body (Figure 2). lateral effective screening tool for sacral fractures often of poor quality inlet view best assessment of sacral spinal canal and superior view of S1 outlet view provides true AP of sacrum findings L4 or L5 transverse process fractures asymmetric foramina anterior pelvic ring disruptions stepladder sign seen on AP view The mechanism of injury is forced eversion with a loaded hindfoot. FRACTURE OF THE LATERAL PROCESS OF THE TALUS. This is often called the snowboarders fracture. Lateral malleolus fracture: This is the most common type of ankle fracture. 2% In order to secure rotational stability, it is necessary to insert a second screw, or if not possible, then a K-wire. Screws are preferable to a K-wire. Epub 2019 Oct 25. Problem Solving in Musculoskeletal Imaging. system of the foot figure 5 the changes in the various process movement and develop ment axes of the ankle during the . angle between line along lateral margin of posterior facet + line anterior to beak of calcaneus. RESULTS AND CONCLUSIONS: Physicians caring for snowboarders should look specifically for fracture of the lateral process of the talus in a snowboarder with a lateral ankle or foot injury.

Kinesiology of the Ankle Brookbush Institute. Occasionally, the fracture will be broken into many pieces (comminuted) that cannot be adequately fixed. Fractures of the cuboid can present with varying swelling and deformity of the lateral midfoot. 1% (12/2124) L 1 A Select Answer to see Preferred Response . Most common ankle fractures. Freiberg's Infraction. They will have difficulty in walking and not able to bear weight. xi. ipsilateral lower extremity fractures common, via artery of tarsal canal (dominant supply), deltoid branch of posterior tibial artery, may be only remaining blood supply with a displaced fracture, Subtalar, tibiotalar, and talonavicular dislocation, best view to demonstrate talar neck fractures, technique is maximum equinus, 15 degrees pronated, xray 75 degrees cephalad from horizontal, best study to determine degree of displacement, comminution and articular congruity, CT scan also will assess for ipsilateral foot injuries (up to 89% incidence), all cases require emergent closed reduction in ER, CT to confirm nondisplaced without articular stepoff, extruded talus should be replaced and treated with ORIF, ~63% of reimplanations do not require secondary procedure, low incidence of infection with adequate I&D and antibiotic therapy, visualize medial and lateral neck to assess reduction, typical areas of comminution are dorsal and medial, between tibialis anterior and posterior tibialis, preserve soft tissue attachments, especially, between tibia and fibula proximally, in line with 4th ray, elevate extensor digitorum brevis and remove debris from subtalar joint, variety of implants used including mini and small fragment screws, cannulated screws and mini fragment plates, medial and lateral lag screws may be used in simple fracture patterns, consider mini fragment plates in comminuted fractures to buttress against varus collapse, subchondral lucency best seen on mortise Xray at, indicates intact vascularity with resorption of subchondral bone, associated with talar neck comminution and open fractures, delayed internal fixation is not associated with avascular necrosis, subtalar arthritis (50%) is the most common, treatment includes medial opening wedge osteotomy of talar neck, decreased motion with locked midfoot and hindfoot, weight bearing on the lateral border of the foot, Adult Knee Trauma Radiographic Evaluation, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries. Thus depending on the size of the fragment, one would use either the 2.4 mm, or the 3.5 mm screw and the corresponding drill bits.Careful technique will ensure that the small lateral process does not fragment. If the fracture is displaced, surgery is usually required to stabilize the fracture with screws ortoremove the fracture fragments. Fractures of the lateral process of the talus in children. the talobular articular surface (as observed in the case reported evaluate the extent of osseous injury, revealed extension of the This is a view taken from the side. Boon AJ, Smith J, Zobitz ME, Amrami KM. The piece that breaks off can vary in size and a single broken piece or many, and whether the pieces shifted away (displaced) or remain in place (non-displaced). Because this is an intraarticular fracture, if displaced, anatomic reduction and stable fixation has to be restored to prevent the development of posttraumatic arthritis. Canale ST, Beaty JH. Leibner ED, Simanovsky N, Abu-Sneinah K, et al. A nice rule to remember is the rule of thirds. {"url":"/signup-modal-props.json?lang=gb\u0026email="}, Morgan M, Hacking C, Hacking C, et al. First branch of the lateral plantar nerve (Baxter's) entrapment. The x-rays and other investigations such as CT or MRI scan can reveal the presence of other injuries that can occur in the vicinity. The fracture occurs when the foot is dorsiflexed and inverted, as can happen with snowboarding (hence the term "snowboarder fracture")1. internally to decrease the likelihood of future instability and talus can result in long-term disability caused by subtalar arthrosis, If the fracture is such that the piece that is broken remains close and not shifted or in other words completely non-displaced, it can be treated with relative immobilization of six weeks to allow adequate healing in a cast orwalker boots. - two processes, lateral & posterior, project from body of talus - either process may be fractured, either as isolated injury or assoc w/ other ankle or talar injuries; - diff dx of posterior ankle pain: ( os trigonum) - embryology: - posterior process arises from secondary ossification center that fuses w/ talar body at about age 12; Imaging A plain x-ray may be diagnostic, but coronal CT scans are often necessary for a complete definition of the injury. The findings can be similar to a severeankle sprain. CT Axial bone window Coronal bone window Sagittal bone window CT Axial bone window Talar fractures of the lateral process and lateral tubercle of the posterior process with extension into the subtalar joint and sinus tarsi. It typically occurs when the foot is jammed suddenly, and the outside of the lower ankle bone (talus) is pushed heavily against the adjoining bone (fibula). . morbidity in otherwise healthy young adults. signicant source of acute ankle pain, particularly in the adolescent surface. 1996;47: 1170-5. If the size of the screw head is more than one third of the size of the fragment, then this small piece may comminute into many pieces. Treatment is emergent reduction of the talus following by internal fixation in an acute or delayed fashion. Fractures of the lateral process of the talus are infrequent but may be a The corresponding T2-weighted images (not shown) demonstrated adjacent mild bone marrow edema and very subtle cystic changes in this region as well. Because this fragment is frequently very small, a K-wire may be used as a joystick to help with the reduction which is carried out with the help of an image intensifier.Because the fragment will not accept more than a single screw, it is best to use a threaded K-wire guide of a corresponding cannulated screw for provisional fixation. They are caused by forced dorsiflexion, inversion, and potentially external rotation and are commonly missed on anteroposterior and lateral radiographs [ 5, 6 ]. ju. Fracture of the lateral process of the talus (snowboarders fracture). With the central K-wire in place, drill the gliding hole with the corresponding drill bit, drilling only the fragment.
