The mortise view better evaluates the talus and all margins of the joint space. The Harris view better evaluates the calcaneus, middle facet of the subtalar joint, and sustentaculum tali. The radiographic appearance often involves comminution of the anterior plafond. The incidence of ankle sprain is highest in sports populations. For the sake of brevity, we will only review the most common fracture types in this article. This can be performed concomitantly with a CT (SPECT-CT). 38 had an avulsion fracture, and the rest showed ligamentous injury or bony contusion. This injury results from ankle inversion or adduction. Then, observe the lateral aspect of the foot and ankle for hematomas or bruises. WBCs (primarily neutrophils) taken from the patient are tagged with In-111 and injected into the patient. Algoritm for Ankle Fractures 2.0. Conversely, a low-frequency (5 MHz to 9 MHz) curved array transducer is better for evaluating deep structures, and more transducer pressure can improve evaluation by decreasing distance to the finding. While all fractures are important to identify, the most concerning for the image interpreter are the ones most likely to be missed. In a left ankle x-ray report of even date, she provided an impression of no acute fracture or subluxation. Ottawa Ankle Rules. A similarly large differential for focal soft tissue uptake includes several acute and chronic diagnoses. 1990 Aug 11;134(32):1541-4. Asymptomatic contralateral sides are not routinely radiographed, however, if a recent or old image of the contralateral side is available, these may also be compared as the skeletal system is generally symmetrical and could therefore act as a reference point. AP images are obtained by directing the x-ray beam from the dorsum of the ankle to the plantar surface, with the image receptor beneath the sole of the foot. - 700+ OSCE Stations: https://geekymedics.com/osce-stations/ These can be difficult to differentiate from trimalleolar fractures on radiographs and may require computed tomography (CT) for further evaluation. The patient usually is given appropriate initial . An ankle x-ray is required only if there is any pain in the malleolar zone and any of these findings: Bone tenderness on the outside portion of the bony part of your ankle, Bone tenderness on the inside portion of the bony part of your ankle. The facility provided by sonography is the dynamic characterization of findings and the high spatial resolution. These account for only about 14% of ankle sprains. A particular concern for vascular disruption should be paid to the talus due to its tenuous blood supply. These features also allow a better evaluation of severe polytrauma patients, as patient positioning is not as important in this modality. The talar body articulates with the calcaneus inferiorly at the middle (anteromedial) and posterior (posterolateral) facets. Anteroposterior view. Please write a single word answer in lowercase (this is an anti-spam measure). The Horizontal Beam Lateral view is useful for assessing soft tissues as well as bones. 2. A 49 year-old male suffered an ankle inversion injury requiring reduction 2-3 weeks prior to imaging and presents with continued pain and swelling. The ankle is allowed to lie distal to the edge of the table so that the weight to the foot provides the gravity stress. Twitter: http://www.twitter.com/geekymedics Daly PJ, Fitzgerald RH, Melton LJ, Ilstrup DM. The AP view is used to evaluate the ankle mortise, though the lateral portions of the talus and tibiotalar joint overlap with the lateral malleolus, obscuring that area from view. [28] Nondisplaced medial or lateral malleolus fractures may only be seen on mortise views. On the mortise view, trace the mortise and the talar dome surface. It is the combination of the imaging findings, the distribution, and the clinical history, which leads to an appropriately narrowed differential diagnosis.[21]. MRI may be especially valuable for early detection of syndesmotic injury in patients with an unclear clinical history, and with equivocal or difficult clinical examinations. Appropriate probe positioning to evaluate specific pieces of anatomy is crucial but beyond the scope of this article. - PSA Question Pack: https://geekymedics.com/psa-question-bank/ Sensitivity and specificity for all of these techniques are high.[26][27]. Though the initial evaluation is with radiography, an understanding of further evaluation with more advanced cross-sectional imaging is also important. Finally, the Saltzman view has been used to determine the relationship of the hindfoot with the leg to characterize complex hindfoot malalignments and is obtained both with and without weight-bearing, with the beam oriented posteroanterior and craniocaudally, tangential to the hindfoot. You have tenderness at the bone over the arch (the navicular bone). Pain after a Negative X-ray - As we noted above, X-ray images aren't as detailed as an MRI. The ankle joint is one of the most commonly injured joints and the most common type of fracture to be treated by orthopedic surgeons. It is important to confirm the following details: In the United Kingdom, two views of the ankle joint are routinely performed: In some cases, a weight-bearing or a stress radiograph (gravity stress or manual stress) may also be required. [6] The fracture line extends vertically from the tibial articular surface proximally to the lateral cortex of the distal tibial metaphysis. These ligaments are located above the ankle joint and between the tibia and fibula. Familiarise yourself with normal radiographs of the ankle, so that you are able to recognise when things dont look quite right. The cephalad aspect of the body (talar dome or trochlea) articulates with the tibia at the tibiotalar joint. On the lateral view, assess the medial, lateral and posterior malleoli, the calcaneum and the base of the fifth metatarsal. Sprains and strains heal quite quickly in children and teens. Book an MRI Scan for Your Ankle Injury at Melbourne Radiology Clinic. Ankle injuries may involve bones or ligaments in isolation, or a combination of bones and ligaments. 10,11,13,14 The instructions and associated figure below layout these guidelines. Abnormal swelling or clinical ankle instability in an acute sprain may be documented with bilateral stress radiographs of the ankle. [18] Any disruption of this well-ordered appearance, especially with an appropriate traumatic or overuse history and physical examination, is suggestive of an injury to these structures. We're excited to see what you do with this new tool - make sure to post examples in the comments! A collection of surgery revision notes covering key surgical topics. An X-ray, or other testing, may be used to determine the degree of severity of the strain or sprain. Diagram of a mortise (on left) and tenon joint. Then, locate the three lateral ligaments and palpate along their course for crepitus and tenderness. Ultrasonographic examination for inversion ankle sprains associated with osseous injuries. CT is obtained in axial projections, and standard coronal and sagittal reformations are performed in soft tissue and bone algorithms. Following venous injection of the radiotracer, the first phase, performed over 60-90 seconds, is the flow or angiographic phase, which demonstrates perfusion of the area. http://creativecommons.org/licenses/by/4.0/. Sonographic evaluation is highly dependent on operator skill and is often performed directly by a musculoskeletal subspecialty-trained radiologist. Posterior malleolus fractures are typically either avulsion at the site of the attachment of the posteroinferior tibiofibular ligament (due to external rotation) or fractures involving the joint surface due to impaction of the talus against the posterior aspect of the tibial plafond (secondary to forced plantarflexion of the foot). An ankle x-ray, also known as ankle series or ankle radiograph, is a set of two x-rays of the ankle joint. On December 2, 2021 she also reported that a right ankle x-ray demonstrated soft tissue edema surrounding the ankle joint, no acute fracture or subluxation, and calcaneal spurs. The lateral view is valuable for evaluating ankle effusions. Similarly, fractures of other tarsal bones should be sought out. The ankle joint allows dorsiflexion and plantarflexion and is one of the weight-bearing joints. High ankle sprains are described as high because they are located above the ankle. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. 2007 Apr;88(4):541-7. doi: 10.1016/s0221-0363(07)89853-2. Surgical treatment of talar body fractures. Other common fracture types involve transverse fractures at, distal, or proximal to the joint line, and these are due to pronation-external rotation forces. Affiliation 1 Chirurgische Klinik und Poliklinik, Klinikum der Universitt Mnchen. Increased radiotracer activity in the delayed phase(s) is nonspecific. and transmitted securely. If you're experiencing pain or swelling in your foot or ankle, but the X-ray came back negative for a break, an MRI can help determine if you're dealing with an incomplete fracture, stress fracture, or ligament injury. [2] It appears that the incidence of these fractures is increasing in developed countries, presumably secondary to the increasing number of people involved in athletic . Ankle Injury Inversion Sprain MOI or Etiology (include anatomy of injury) Symptoms Signs Palpation Findings Special Discomfort when trying to walk 6 . They form what is known as the syndesmosis (pronounced "SIN-des-MO-sis"). Foot Xray not needed for mid- Foot Pain if both . . As mentioned above, fractures of the proximal fifth metatarsal may be seen only on lateral ankle views and may not be apparent on foot radiographs. The talar anatomy is complex and is divided into the head, neck, and body. An X-ray, ultrasound, or MRI is often needed to confirm a lateral ligament tear and rule out other injuries. Update on talar fracture patterns: a large level I trauma center study. Cine images are valuable for evaluating large masses, demonstrating the origin of the mass, and demonstrating spatial relationships to adjacent structures. Access free multiple choice questions on this topic. There is little role for MRI in the emergent setting, as the high signal characteristics of edema and hemorrhage are nonspecific and may obscure other abnormalities. Instagram: https://instagram.com/geekymedics The ankle is a hinge joint formed by three bones: the tibia, the fibula and the talus. Additional normal anatomic variants are important to appreciate, as they may be confused for fractures. Would you like email updates of new search results? Ankle fractures in children are relatively less frequent, but when they do occur, they tend to involve the epiphysis (Salter-Harris fractures), as the open physeal plate is a plane of weakness in any bone. Geeky Medics accepts no liability for loss of any kind incurred as a result of reliance upon the information provided in this video. ), Bimalleolar fracture (medial + lateral malleoli fractures), Trimalleolar fracture (medial + lateral + posterior malleoli fractures). The ankle sprain is one of the most common injuries seen in podiatric and orthopedic practice. [1]The estimated incidence of ankle fractures is approximately 187 per 100,000 people per year. Ultrasound findings include thickening and hypoechogenicity of the affected ligament in case of a sprain. Rieger M, Mallouhi A, Tauscher T, Lutz M, Jaschke WR. A benefit is using DSA is the real-time nature of the examination, allowing selective and sub-selective catheterization of distal arteries and the ability to intervene at the time of the examination. Multiple specialized radiographic views of the ankle have been described for specific purposes. [4] The overall incidence is fairly equivalent between sexes, though higher in young males and older females. Symptoms that persists beyond a few days or do not improve. A tear will show an anechoic defect, a loss of continuity or absence of the ligament. Assess the joint space on the mortise view. Lateral ankle inspection and palpation. Rest is achieved by limiting weight-bearing. In this lecture we present a simple algoritm that helps you to find: All ankle fractures, even the ones that are not visible on the X-rays Internal oblique images are obtained by internally rotating the ankle 1520 degrees and directing the x-ray beam in a dorsoplantar direction similar to the AP view. . - Over 3000 Free MCQs: https://geekyquiz.com/ Differences in radiotracer activity are due only to differences in the flow. [5][8] This view is also important for evaluating swelling about the medial or lateral malleolus. Differences in activity in this phase are caused by differences in flow and in capillary dilatation, which is nonspecific and secondary to inflammation. A small degree of uniform, symmetric osseous radiotracer activity within the foot and ankle is normal. Ankle fractures are created by the movement of the talus within the ankle mortise, with leverage exerted by the foot. Stress X-rays are done to see if the tibia and fibula splay apart. - Geeky Medics OSCE App: https://geekymedics.com/geeky-medics-app/ Newer nuclear medicine techniques for the evaluation of osseous lesions include positron emission tomography (PET) combined with CT (PET-CT) using F18-NaF. Normally, after 2-3 weeks you will have decreased range of movement, strength and balance from your ankle injury. X-ray Determines the Degree of Severity of the Strain or Sprain Most people with mild strains and sprains can treat these injuries simply at home with the use of the RICE method of care. Yu SM, Yu JS. The lateral process of the talus is best evaluated on AP ankle radiographs. However, there is typically some combination of T1 or proton density-weighted images, T2-weighted images, short inversion time recovery (STIR), or T2-weighted fat-saturated sequences. . Saliou G, Kocheida M, Vernois J, Bonnaire B, Lehmann P, Vanden Abeel B, Boulu G, Le Blanche AF, Valle JN. But don't avoid all physical activity. The ankle joint: imaging strategies in the evaluation of ligamentous injuries. When describing an ankle X-ray, use the following structure: Anatomical descriptors of ankle fractures include (but are not limited to): Lateral malleolus fractures can be further classified, as per the Danis-Weber classification (commonly referred to as just the Weber classification), into: Today, were REALLY excited to announce Geeky AI; an intelligent assistant to help you write flashcards.

Many times, this injury is taken for granted because of the frequency of its presentation. transverse, oblique, spiral) Simple or comminuted Displacement and angulation of the distal fracture fragment in relation to the proximal fracture fragment Please enable it to take advantage of the complete set of features! Type III fractures may involve either the medial malleolus or the lateral aspect of the distal tibia growth plate at the anterior tubercle. With the ankle joint held at 10 to 15 of plantar flexion, the examiner grasps around the heel with one hand and stabilizes the tibia from the anterior side with the other. Beware of normal developmental variants such as accessory ossicles which may be mistaken for fractures. This is the widest distance between the medial border of the talar bone and the lateral border of the medial malleolus. Radiography remains the principal imaging evaluation of the ankle. [Article in German] Authors H Polzer 1 , B Ockert, S Grote, C Volkering, W Mutschler, K G Kanz. These are typically well evaluated on AP and lateral views. As with any infectious or inflammatory process, WBCs will localize to a site of inflammation. 9 The most common injury was ankle ligament sprains, 2, 14-17 mostly involving the lateral ankle ligaments. Additionally, the real-time image acquisition nature of ultrasound and angiography obviates the need for special patient positioning in these situations. High Ankle Sprain & Syndesmosis Injuries are traumatic injuries that affect the distal tibiofibular ligaments and most commonly occur due to sudden external rotation of the ankle. The gravity stress view is obtained using a cross-table projection of an externally rotated foot and ankle, with the affected side-lying upward. Instagram: https://instagram.com/geekymedics An ankle x-ray, also known as ankle series or ankle radiograph, is a set of two x-rays of the ankle joint. Keep the back knee straight to feel a stretch! Avulsion fractures can occur at midfoot and hindfoot tarsal bones. Typically, a special stand with steps is used, with a slight cut into the top step used to hold the x-ray cassette. This video demonstrates how to apply a warm compress to the eye and clean away debris. References 1 The true incidence of ankle sprains in the general population is unknown because more than half of all ankle injuries go untreated. The physiotherapy treatment of a sprained ankle. Always adhere to medical school/local hospital guidelines when performing examinations or clinical procedures. MRI has been shown to be the most sensitive and specific evaluation for musculoskeletal infections, including cellulitis, abscesses, and osteomyelitis. Disclaimer, National Library of Medicine MRI Common indications include prolonged pain after conservative management, or to exclude more extensive injuries. Rogers LF. X-ray. When suspected, x-rays of the tibia and fibula should be obtained. Broden views are superior for imaging the subtalar joint and are obtained with the patient in supine, knee slightly flexed, and supported by a sandbag, with the foot in neutral dorsiflexion. In complex cases, an MRI scan is ordered for analyzing the injured ligament. The ankle joint and the joints of the feet should be assessed and compared. This has been termed the snowboarders fracture and is typically only seen on the AP ankle view. Failure to identify such fractures can lead to delayed diagnosis and suboptimal management, including growth plate disturbance (in pediatric patients), persistent pain and instability, fracture nonunion, and accelerated osteoarthrosis. Perhaps the most commonly missed ankle fracture is the anterior process of the calcaneus and may only be seen on the lateral radiographic view. Carra BJ, Bui-Mansfield LT, O'Brien SD, Chen DC. Treatment of a sprained lateral ligament of ankle Almost all pulled ligaments in the ankle can be treated without surgery.

Type III fractures tend to occur after the central portion of the physis has already fused, typically around age 12 to 13 years. Real-time multiplanar reformations can be performed at the workstation, and 3D surface renderings can now be easily created to further assist the surgeon in planning. Talar Fractures and Dislocations: A Radiologist's Guide to Timely Diagnosis and Classification. Even if you're seeking medical help, ice the area immediately. Fractures involving the medial and lateral malleoli are termed bimalleolar fractures. Clipboard, Search History, and several other advanced features are temporarily unavailable. Vallier HA, Nork SE, Benirschke SK, Sangeorzan BJ. Treatment. In particular, evaluation for tendinosis, tear, or rupture of the Achilles tendon is easily performed with ultrasound due to its superficial location. Ideally, you should be able to see at least the distal third of the tibia and fibula and the talus on the mortise view and in addition to those, you should be able to see the calcaneum and the base of the 5th metatarsal on the lateral view. 3. A comprehensive collection of OSCE guides to common clinical procedures, including step-by-step images of key steps, video demonstrations and PDF mark schemes. This tendon has an approximate average AP diameter of 6 mm. Adapted by author. These typically occur at the medial and lateral corners of the talar dome. Epidemiology An ankle sprain is a common injury. You might also be interested in our awesome bank of 700+ OSCE Stations. X-rays pass through body structures onto specially-treated plates (similar to camera film) and a "negative . It usually is incurred from an inversion force on the ankle, but eversion forces also can traumatize the ankle. A fracture in an abnormal bone is termed a pathological fracture. An impaction fracture of the anterior tibial plafond with the foot in inversion and dorsiflexion is termed a pilon fracture. TikTok: https://www.tiktok.com/@geekymedics The radiographic search pattern must include the evaluation of the soft tissues for swelling. Vascular injuries may present as intraluminal thrombus, dissection flap, non-opacification of a vessel due to occlusion, or extravasation of contrast correlating with active hemorrhage from mural disruption.
