Multiple anterior osteophytes can occur with severe osteoarthritis of the ankle. This anatomic structure represents a separate ligament rather than a distal component of the AITFL. talocalcaneal joint the clinical subtalar joint, i.e. In the middle of the stance phase (midstance), the foot is at its most pronated point. McMurray stated that the footballers ankle was peculiar to the professional soccer player, especially those older than 25 years who have played for many years. Foot Ankle Int. The common history of patients with anterior ankle impingement is recurrent inversion sprain. 2020 . Discontinue the medication if any side effects are noted, including, but not limited to: stomach upset, rash, swelling, or change in stool color. Khaled M. Sarraf, BSc (Hons), MBBS, MRCS Specialist Registrar in Trauma and Orthopaedic Surgery, North West Thames Rotation - London Deanery, Chelsea and Westminster Hospital NHS Foundation Trust . To demonstrate the MR imaging findings of anterolateral impingement (ALI) of the ankle. Nikolopoulos and coworkers26 considered this fascicle to be an independent accessory ligament. Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Uzel M, Cetinus E, Bilgic E, Karaoguz A, Kanber Y. When the heel first strikes the ground, the foot is supinated. The sinus tarsi is located immediately anterior to the posterior subtalar joint, and is separated from this joint by the joint capsule and the short but stout talocalcaneal interosseous ligament. The weight-bearing lateral view with the ankle in maximal dorsiflexion (i.e., pli view) demonstrates anterior impingement, and this view commonly is used in evaluating dancers. Posterior ankle impingement (PAI) syndrome is one of the impingement syndromes involving the ankle. The main advantage of surgical repair of an acute Achilles tendon rupture, when compared with nonsurgical management, is reduced. Furthermore, you can find the "Troubleshooting Login Issues" section which can answer your unresolved problems and equip you . If you grab your heel, the big bone you are holding is the calcaneous bone. He teaches as an Assistant Professor of Orthopedics at Emory School of Medicine in Atlanta, Georgia. 1Department of Radiology, Konkuk University Medical Center, Konkuk University School of Medicine, 120-1 Neungdong-ro, Gwangjin-gu, Seoul . A coronal fat-suppressed proton density-weighted image obtained just anterior to the posterior subtalar joint reveals the extra-articular subcortical bone marrow edema and cystic changes at both the talocalcaneal region (arrowheads), and the calcaneofibular region, with bony remodeling and flat neo-facets at the fibula distally and at the adjacent lateral calcaneus (red arrows). Surgery may be effective in the rare case that does not resolve with non-surgical treatment. De-identified images were assessed by one senior musculoskeletal radiologist for findings associated with posterior ankle impingement syndrome (os trigonum, Stieda process, posterior talocrural and subtalar joint effusion-synovitis, flexor hallucis longus tendon pathology and tenosynovitis, and posterior ankle bone marrow oedema). Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. The critical angle of Gissane was devised on lateral radiographs to evaluate calcaneal fractures, as commonly the talar lateral process is driven downward into the adjacent relatively weak part of the calcaneus5. External rotation . But the subtalar joint also plays a small role in these motions. A prospective study of prognostic factors concerning the outcome of arthroscopic surgery for anterior ankle impingement. This is especially seen in ballet dancers. On this page: Article: Clinical presentation Pathology Radiographic features Treatment and prognosis References Images: Cases and figures The MR imaging studies were assessed for the presence of abnormal bone marrow signal intensity, osseous lesions, and soft-tissue abnormalities.

Because this injury involves ligaments located above the ankle joint it is sometimes called a high ankle sprain. The ankle joint, known as the talocrural joint, is primarily responsible for dorsiflexion and plantar flexion. 1999 Aug;81(8):1147-54. http://www.jbjs.org/article.aspx?volume=81&page=1147 (full text), 7 The effects of adult acquired flatfoot deformity on tibiotalar joint contact characteristics. 2006;187 (1): W53-8. You may also notice some swelling on the outside of the hindfoot. Together they form the cabinet which establishes guidelines for state policy, allocates tasks among the various ministries, and passes draft statutes which come before the Landtag where they are put to the vote. The first series reported by Biedert3 had a success rate of approximately 67%. The medial, rather than the lateral, calcaneal wall is selected for MR measurements because it has less variability and fewer bony protuberances. 123 Fundamentals of General Surgery Francesco Palazzo Editor. Nikolopoulos and coworkers 26 considered this fascicle to be an independent accessory ligament. The osteophytic prominence causes bony impingement, often increases in size, and eventually may break off, forming a loose body. Several conditions can mimic the anterior impingement syndrome, including osteochondritis dissecans of the talus, a high ankle sprain involving the anterior tibiofibular ligament,19 impingement by Bassetts ligament,1 an aberrant distal insertion of the anterior tibiofibular ligament that can cause persistent symptoms, Ferkels disease,16 an accumulation of debris and synovitis in the anterolateral gutter, degenerative joint disease of the tibiotalar or talonavicular joints (especially in the early phases when the radiographic findings are subtle), and a stress fracture or an osteoid osteoma in the tarsal navicular. This can result in anterolateral impingement, with pain elicited upon dorsiflexion of the foot. (Tarsal is the latin word for ankle.) The image on the right depicts the plane just anterior to the posterior subtalar joint demonstrating normal alignment and spacing between the lateral talus (asterisk), the lateral calcaneus (arrowhead), and the lateral malleolus (arrow). 2006 Oct;23(4):695-708 http://www.ncbi.nlm.nih.gov/pubmed/17067888. Studies show that range of motion in the subtalar joint is 20% to 30% lower in older adults compared to younger people. Anteromedial osteophytes of the tibia and the talus. Talofibular as well as calcaneofibular extra-articular bony impingement with subcortical bone marrow edema (arrowheads) is present. 2010;195 (3): 595-604. The so-called athletes ankle was first mentioned in the orthopedic literature by Morris. Capsular disorders are those that primarily impair the subtalar joint and its ability to function properly. Posterior hindfoot impingement most commonly occurs in middle-aged and older individuals with a chronic hindfoot valgus deformity. Fundamentals of General Surgery. Bassetts ligament impingement is caused the distal fascicle of the anteroinferior tibiofibular ligament. On physical examination, the anteromedial aspect of the ankle appears swollen and is tender to palpation over the anterior tibiotalar fascicle of the deltoid ligament. There is little or no additional information gained through indirect magnetic resonance (MR) arthrography for evaluating anteromedial impingement compared with conventional MRI.18. 5-5) has been developed to aid in the detection of anteromedial spurs, and it is obtained with the beam tilted in a 45-degree craniocaudal direction with the leg in 30 degrees of external rotation and the foot in plantar flexion in relation to the standard lateral radiograph position.23 The sensitivity of lateral radiographs for detecting anterior tibial and talar osteophytes is 40% and 32%, and their specificity is 70% and 82%, respectively. Capsular disorders include: Non-capsular disorders are those in which the subtalar joint is indirectly affected or affected as a result of another defect or injury to the foot or ankle. Examples include: Injuries or disorders of the ankle and foot can be diagnosed and treated by a podiatrist (foot doctor) or an orthopedist (bone, joint, and muscle specialist). The damage can often be deeply felt and be difficult to pinpoint without imaging tests, such as an ultrasound. Osseous findings of lateral hindfoot impingement include extra-articular subcortical bone marrow edema at specific locations at the talus, calcaneus or fibula. There are four indications for AITFL resection: AANA Advanced Arthroscopy The Foot and Ankle. 2021 Jun;6(2):22. doi:10.3390/biomimetics6020022, Sebastian D. The active supination dorsiflexion test guided therapeutic intervention for shin and calf pain: a case report. Decreased range of motion puts one at risk for foot pain, something that one in four older adults experience. . Pressure over a joint in the open position is held while the joint is moved to a closed position recreating the impingement event. In all patients, MR imaging demonstrated abnormal bone marrow signal intensity in the os trigonum and/or lateral talar tubercle, consistent with bone contusions. Patient usually present with swelling after activity and with limited ankle dorsiflexion movement. Orthopaed and Trauma. Pronation requires a combination of dorsiflexion, abduction, and eversion. The corresponding fat-suppressed T2-weighted image demonstrates the normal rounded to slightly pointed apex of the lateral talar process (arrow), and the unremarkable cervical ligament (arrowhead). Also demonstrated is unremarkable articular cartilage at the posterior subtalar joint (arrow). Arthroereisis is a surgical technique which aims to limit motion at a hypermobile joint. A special oblique anteromedial impingement view (Fig. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [ 12 ]. The measurement is performed on the most posterior coronal image that includes both the tibia and calcaneus, taking care not to use an image through the calcaneal sustentaculum tali as that would increase the angle. In July 2010 an excavation was undertaken in the car park of the Masonic hall at Bawtry, South Yorkshire as part of a field school run by the Department of Archaeology, University of Sheffield, with support from Wessex Archaeology (Sheffield). Robinson and associates. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. A 4mm arthroscope was used to visualise the joint surface. Book appointments Online, View Fees, User Feedbacks. Its development relates to hindfoot valgus malalignment, and a lateral shift of the calcaneus which may lead to abnormal bony contact between the talus and calcaneus specifically at the posterior peripheral margin of the sinus tarsi, and sometimes also the development of neofacets at the sinus tarsi, as well as at the fibula and adjacent calcaneus. Subtalar arthritis is a painful grinding and wearing down of the tissues between the talus and your heel bone, called the calcaneus. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Weerakkody Y, Yap J, Sharma R, et al. CHAPTER 5 Bony Impingement of the Ankle and Subtalar Joints, Ankle sprains are one of the most common injuries seen in sports medicine, and most heal without persistent pain or chronic disability.1,2 However, some patients with ankle sprains continue to have persistent pain and dysfunction.2,3 Two common sources of chronic pain and disabilitypersistent ankle instability and impingementmay occur separately or concomitantly. Controversy exists about the cause of bony osteophytes around the ankle with normal articular cartilage. originated from the anteromedial border, and could remain undetected due to overprojection or superposition of the lateral part of the talar neck and body and the prominent anterolateral border of the distal tibia, respectively. Without it, you would constantly roll your ankles when you run, jump, or walk. Affected patients may also experience subluxation or dislocation of the peroneal tendons, causing a popping sensation at the posterior margin of the lateral malleolus. The pain generally grows worse throughout the day, as weight-bearing activities are performed. Van Dijks 1997 radiographic classification (Table 5-2) was based on osteoarthrosis of the ankle on plain radiographs (Fig. American Academy of Orthopedic Surgeons. ), Use an oral anti-inflammatory medication. This instability is not related to the lateral impingement, but rather is caused by severe hindfoot valgus malalignment, and resultant overactivity of the unopposed peroneus brevis in the presence of posterior tibial tendon insufficiency. Bone marrow cystic changes are present at the lateral talar process and the calcaneofibular region (arrowheads), and soft tissue fullness and edema is noted at the lateral soft tissues of the hindfoot (red arrow). more. MR imaging of ankle impingement syndromes. The subtalar joint's primary responsibility is to facilitate gait movements. Anterior impingement syndrome of the ankle is the most common cause of anterior ankle pain in many sports participants. Generally, the subtalar joint is complex consisting of the calcaneus (heel bone) below and the talus above. Bassetts ligament impingement is caused the distal fascicle of the anteroinferior tibiofibular ligament.1 It is a thickened distal fascicle of the anteroinferior tibiofibular ligament (AITFL) that extends far distally on the lateral malleolus. COVID-19: Latest updates about the vaccine, testing, how to protect yourself and get care, Updated visitor policy | Services and hours updates. Foot Ankle. The subtalar joint: A complex mechanism. It is usually a unilateral phenomenon. 9 Incidence and morphologic characteristics of benign calcaneal cystic lesions on MRI. These clinical symptoms are not specific and may also be encountered in patients with subtalar degenerative arthritis, sinus tarsi syndrome, and other disorders affecting the hindfoot region. Subtalar arthroscopy was used to evaluate the AALTF surface characteristics. Failure of visualisation of the middle subtalar joint in the lateral view, and 5. TABLE 5-2 Classification of Osteoarthritic Changes of the Ankle Joint. The common history of patients with anterior ankle impingement is recurrent inversion sprain. Iowa Orthop J. Morris. Furthermore, your foot and ankle's ability to glide and rotate in different directions is crucial to you being able to adapt your footing to shifting or uneven terrain. Intraoperative imaging may be needed to ensure adequate removal. In some cases, multiple imaging tests may be needed to reveal hidden fractures known as occult fractures, which are frequently missed in the heel area. The prevalence of lateral hindfoot impingement has been found to increase with higher grades of posterior tibial tendon tear2. FIGURE 5-4 A, Loose body in a female basketball player with recurrent ankle sprains. The MRI hindfoot valgus angle measurement suggested in the literature has been adapted from methods using frontal weight-bearing radiographic studies and CT reconstruction exams. The bony changes sometimes are seen to also involve the adjacent subcortical region of the anterosuperior calcaneal process (13a), however if bone marrow edema is present all along the cortex around the margins of the sinus tarsi, this would not be characteristic and would instead suggest a diagnosis of sinus tarsi syndrome. 2015;61(1):381-388. doi:10.1159/000368357, Krahenbuhl N, Horn-Lang T, Hintermann B. The corresponding sagittal STIR image shows edema throughout the sinus tarsi with subcortical bone marrow edema along the talus and calcaneus at margins of the sinus (arrows). Nine patients with a history of ankle inversion injury and chronic lateral ankle . The MR examination also showed characteristic features of lateral hindfoot impingement. 2008; 28: 1-8. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2603342/, 5 Fractures of the Calcaneus: A Review with Emphasis on CT. Daftary A, Haims AH, and Baumgaertner MR. Radiographics25, September 2005:1215-1226 http://radiographics.rsna.org/content/25/5/1215.full (full text), 6 Subluxation of the talocalcaneal joint in adults who have symptomatic flatfoot. Cerezal L, Abascal F, Canga A et-al. The pain originates when the subtalar joint repetitively jams (impinges) while performing weight-bearing activities. Talar tilt test-g. This can include talocalcaneal, calcaneofibular (subfibular) or combined talocalcaneal-subfibular impingements. Wear supportive shoes. Anterior dbridement is of questionable effectiveness. Subcortical bone marrow edema characteristically involves both opposing aspects of the talus, calcaneus, or fibula (3a). Magnetic resonance imaging (MRI) after ankle trauma often shows alteration of bone marrow signal with a low signal on T1-weighted and a high signal on T2-weighted and fluid-sensitive sequences (like short tau inversion-recovery (STIR) or fat-suppressed (FS) sequences). Guide: Limbs and Spine MRCS Revision Guide: Limbs and Spine Mazyar Kanani, PhD, FRCS (CTh) Fellow in Congenital Cardiac Surgery, Children's Hospital, Pittsburgh, Pennsylvania, USA. (Custom foot orthoses are not a covered benefit of the Kaiser Permanente Health Plan. 1. a (1) : the action or process of rotating on or as if on an axis . ligament anatomical structure significance relatively morphology functional unknown. Initially anterolateral impingement was described as a clinical diagnosis of exclusion only made in the absence of mechanical instability and tendon abnormality [ 11 ]. Some spurs occur primarily on the lip of the tibia. The main impingement syndromes are anterolateral, anterior, anteromedial, and posterior impingement. 1 posterior ankle impingement syndrome refers to a group of abnormal entities that result from repetitive or acute forced plantar flexion of the foot. A fat-suppressed coronal proton density-weighted image in a 53 year-old woman with sequelae of remote displaced fractures (arrows) with a hindfoot valgus fixed deformity and 2 year history of diffuse ankle pain. TABLE 5-1 Classification of Anterior Ankle Impingement. This tissue secretes fluid to lubricate the joint space, protecting the cartilage and bones from damage. Osteophytes are protrusions of bone and cartilage around the joint space. Administer cortisone injections. 1) [ 1, 2, 4, 5 ]. may remain hypertrophied, with tissue extending into the anterolateral gutter. Impingement sign- positive test results when patient experiences pain with pressure over the anterolateral ankle and when the pain response is greater with the ankle in dorsiflexion and eversion than in plantar flexion l. . The anterior impingement syndrome of the ankle is a strangulation that can be caused by soft tissue, like the joint capsule or scar tissue, and hard tissue which refers to bone tissue. Four other weaker ligaments provide the joint with added stability. The procedure has evolved from early use of a bone block placed into the sinus tarsi for extra-articular arthrodesis, to placement of a metal or plastic implant configured to specifically block the anterior translation of the lateral talar process towards the floor of the sinus tarsi, aiming to limit hindfoot eversion11. 2. The joint is classed structurally as a synovial joint, and functionally as a plane synovial joint. Ananthakrisnan D, Ching R, Tencer A, Hansen ST Jr, Sangeorzan BJ. Lateral hindfoot impingement is an extra-articular osseous impingement affecting the talus, calcaneus and distal fibula. You should use as many of these treatments as possible concurrently: Need to aska question, email your doctor, search our Phone Directory, talk to a pharmacist or advice nurse, get the information you need. Donovan A, Rosenberg ZS. Evaluate the TCO of your PACS download >, 750 Old Hickory Blvd, Suite 1-260Brentwood, TN 37027, Focus on Musculoskeletal and Neurological MRI, Developmental Talocalcaneal Coalitions and Associated Conditions, Hammer, Mallet, and Claw Toe Deformities of the Lesser Toes. The osteophytes were related to direct trauma associated with the impingement of the anterior articular border of the tibia in the talar neck during forced dorsiflexion of the ankle joint. Most features are available only to members receiving care at Kaiser Permanente medical facilities. Cortisone does not replace the need for supportive shoes, foot orthoses, calf stretching, and other physical measures. Conversely, the subtalar joint moves the ankle outwards (eversion) and inwards (inversion). CT and MR imaging of patients with lateral hindfoot symptoms have demonstrated features of extra-articular osseous impingement laterally, involving the talus, calcaneus and fibula. J Musculoskelet Disord Treat. Contact between the AITFL and the talus is prominent at the beginning of plantar flexion and inversion of the ankle. The damage may be broadly described as capsular or non-capsular. EFORT Open Rev. With more severe hindfoot valgus and lateral calcaneal subluxation additional impingement may occur between the lateral malleolus and lateral calcaneus as depicted on the right. It is classically described in ballet dancers. This means that they are closest to the part of the ankle that attaches to the rest of your body. The Lower Saxony state government. A fibrofatty septum separated the AITFL from the accessory fascicle, similar to the one that covered the intermediate space between the interosseous and the anterior tibiofibular ligament.26 The lateral shoulder of the talus impinges against the distal fascicle of the AITFL when the ankle is plantar flexed. Fifteen cases of soft tissue impingement and 14 cases of anterior bony impingement were included in the study. An axial T1-weighted image in a 71 year-old woman with left ankle pain, swelling and difficulty with weight-bearing, showing a longitudinal split tear of the posterior tibial tendon (arrows). A ankle syndesmosis injury is a severe form of ankle sprain that also causes damage to other ligaments that support the ankle . The term Stieda process is used, when the lateral tubercle is very prominent. There is little or no additional information gained through indirect magnetic resonance (MR) arthrography for evaluating anteromedial impingement compared with conventional MRI. At the Centeno-Schultz Clinic, we have successfully treated subtalar joint pain and other ankle injuries with bone marrow concentrate and PRP injections. The three subtalar facets are in the groove between the top of the calcaneous bone and the bottom of the talus bone. 3. Numerous investigators have reported good results with open arthrotomy, but it can be complicated by cutaneous nerve entrapment, wound dehiscence, damage of the long extensor tendons, and formation of hypertrophic scar tissue.7,11,17 In recent years, the arthroscopic treatment of anterior ankle impingement has had a high success rate. Jeffrey E. Martus, John E. Femino, Michelle S. Caird et al. Convert impact exercise to non-impact exercise cycling, swimming, and pool running are acceptable alternatives. Adjacent or articulating bones that are repetitively in contact can stimulate the cambium layer, the deep layer of periosteum that has osteogenic potential, to form osteophytes. Conservative treatment with rest, physical therapy, shoe modification, or local injection constitutes first-line therapy for most cases of anterior ankle impingement. Hindfoot valgus malalignment is a requisite for lateral hindfoot impingement to develop. Some great exercises for this include walking in sand or water, or even picking up marbles and other small objects with your toes. The talus articulates with the os calcis so that the axis of the talus is roughly in line with the first web space of the foot and the axis of the os calcis is in line with the fourth web space. Location. Radiology 219, June 201:802-810. http://radiology.rsna.org/content/219/3/802.full. Lektrakul N, Chung CB, Lai Y et al. If all modalities of conservative treatment are unsuccessful, operative treatment may be indicated. This measurement has limitations related to the short segment of tibia included on ankle MRI exams being insufficient for an accurate long axis determination, and the medial wall of the calcaneal tuberosity gradually slopes towards vertical also in cases of severe valgus malalignment, so it is important to perform the measurement between the sustentaculum and the calcaneal tuberosity; available slice selection also somewhat limits reproducibility. This hindfoot malalignment is often due to posterior tibial tendon insufficiency, as this tendon is crucial in maintaining the longitudinal arch of the foot. Acute injuries may be treated with ample rest and ice application. 1A, 1B ). Bassett's ligament impingement is caused the distal fascicle of the anteroinferior tibiofibular ligament. Design and patients. Subcortical sclerosis, representing regions of bone formation replacing marrow fat, is seen as low signal on both T1 and T2-weighted images, located at region of maximal bony impact, often with adjacent bone marrow edema (14a). The anterocentral site is the classic location of anterior ankle impingement. They result from injury to the deltoid ligament complex, leading to scar formation and synovitis along the anteromedial joint line. We are here to help. From Scranton PE Jr, McDermott JE. Abstract Objective. (We recommend over-the-counter ibuprofen. A fat-suppressed T2-weighted sagittal image in a 34 year-old man with a history of an ankle sprain 2 weeks prior, demonstrates an incidental finding of cystic changes at the calcaneal body (arrow), typical for an intraosseous ganglion cyst. The goal of surgery is removal the osteophytes to restore the anterior space and to reduce the chance of symptoms recurring. Supination causes the subtalar joint to lock, creating a rigid lever that allows the toes to lift from the ground. anatomy shoulder ray rotation internal normal labelled radiographic skeleton xray radiology medical ap hombro uwmsk human bones anatomia anatoma student. The subtalar joint allows you to move your foot side-to-side (laterally), pivot to change directions, and stay balanced as you move across uneven terrain. Over time, attempted repair with resultant fibrosis and fibrocartilage proliferation leads to the formation of osteophytes. Systemic side effects of this type of injection are extremely rare. With more advanced changes, there will be cortical remodeling leading to flattening of the bony contours at the contact site, and neofacet formation (15a). Bilateral posterior ankle impingement syndrome has been described but is rare 5 . 1- stiffn Impingement, which is entrapment of an anatomic structure that leads to pain and decreased range of motion of the ankle, can be classified as soft tissue or osseous.4, Osseous or bony impingement most commonly results from spur formation along the anterior margin of the distal tibia and talus or from a prominent posterolateral talar process (i.e., os trigonum). Subtalar instability (STI) is a chronic functional talocal- . Cortisone is typically injected at 2 month intervals, until the condition resolves or 3 injection have been administered, whichever comes first. The problem usually develops without an acute injury. Gerontology. With a significant hindfoot valgus deformity, there will be a lateral shift of the main weightbearing forces at the ankle and hindfoot, from the talar dome towards the lateral talus and also to the fibula7. 5-2). Posterior-ankle impingement (PAI) syndrome describes a group of pathological entities that result from repetitive plantar flexion of the foot that causes repeated compression and entrapment of soft tissues, bony processes or unfused ossicles between the posterior-tibial plafond and the superior surface of the calcaneum. . Anteromedial ankle pain is caused by impingement of the anterior portion of the medial malleolus on a spur on the medial shoulder of the talus. A talar beak. J Foot Ankle Surg 2014; 53:485. Add a good arch support or orthotic in your shoe. Normally the sinus tarsi extends into a small space between the apex of the lateral process of the talus and the adjacent calcaneus, just anterior to the posterior subtalar joint margin, and the adjacent talar lateral process is normally rounded or slightly pointed, without a flat facet (8a,9a). With a fixed deformity, or significant malalignment, surgery including calcaneal osteotomy is usually required and may provide hindfoot realignment without the restriction of movement of a fusion. 10 Figure 10:A fat-suppressed proton density-weighted image, obtained coronal to the apex of the angle of Gissane in a 54 year-old woman showing normal talocalcaneal alignment, with a normal interval between the lateral malleolar tip and the lateral calcaneus (arrow), and normal position of the peroneal tendons (arrowheads). There were statistically significant decreases in subjective analog scores. Menz HB. Physical examination reveals anterior tenderness and thickening of the synovium, often with an effusion, palpable osteophytes with the ankle in slight plantar flexion, limited dorsiflexion when compared with the opposite ankle, and a positive dorsiflexion impingement sign (i.e., pain with forced dorsiflexion of the ankle when the knee is flexed). . LoginAsk is here to help you access Subtalar Joint Radiology quickly and handle each specific case you encounter. FIGURE 5-3 A, Osteophytes without joint space narrowing (Scranton type III, Van Dijk grade I). It's location is the anterior side of the ankle in the talocrural joint. Adjacent or articulating bones that are repetitively in contact can stimulate the cambium layer, the deep layer of periosteum that has osteogenic potential, to form osteophytes. Catherine Moyer, DPM, is a podiatrist experienced in the diagnosis, treatment, and prevention of disorders of the foot and ankle. The talus and calcaneous bones are proximal tarsal bones. The typical patient is a young athlete presenting with chronic anterior ankle pain.17 Pain likely results from entrapment of hypertrophied synovial tissue between the talus and the anterior tibia, which is exacerbated by the presence of anterior spurs. Narrowing of the joint space increased in 47% of patients with grade II osteoarthritis.9, Anteromedial ankle pain is caused by impingement of the anterior portion of the medial malleolus on a spur on the medial shoulder of the talus. Osteophytic formations occur with weight-bearing articular cartilage damage, such as osteoarthritis of the hip and knee, and occur without weight-bearing articular cartilage damage, such as bony impingement lesions. This accessory, or distal, fascicle is separated from the anteroinferior tibiofibular ligament by a fibrofatty septum (Fig. Lateral hindfoot impingement is characteristically not related to an acute injury, but to chronic hindfoot valgus malalignment. American Journal of Radiology, September 2009, Vol. Repetitive forced dorsiflexion also can result in impaction-related microtrauma of the anterior chondral margin of the tibiotalar joint. Malicky ES, Crary JL, Houghton MJ et al. Stem cells can fill in areas of cartilage loss (8). The fascicle is bent on the anterolateral edge of the talus with dorsiflexion and dorsiflexion-inversion. Clinical presentation These osteophytes are easy to miss (i.e., hidden spurs). The osteophytic prominence causes bony impingement, often increases in size, and eventually may break off, forming a loose body. While pronation and supination are the subtalar joint's primary responsibilities, the separate actions involved in pronation and supination also involve other parts of the foot and ankle. This ligament is responsible for preventing anterior talar translation relative to the tibia and therefore is analogous to the anterior cruciate . Palmer W, Bancroft L, Bonar F, Choi JA, Cotten A, Griffith JF, Robinson P, Pfirrmann CWA. Journal of Bone and Joint Surgery (Am) 2002 November 84-A: 2005-2009 http://www.jbjs.org/article.aspx?Volume=84&page=2005 (full text), 2 Extra-articular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. See your doctor if you have failed to respond to the above regimen after a two month trial. Take three 200mg tablets, three times per day with food breakfast, lunch, and dinner. Anterolateral impingement test: Thumb pressure applied over the anterolateral gutter with the foot in plantarflexion will push any hypertrophic synovium into the joint causing pain. Similar terms such as sinus tarsi impingement, talocalcaneal impingement and subtalar impingement have also been used in the orthopaedic literature.

Calcaneal intraosseous ganglion formation or prominence of vascular structures may mimic the calcaneal changes of lateral hindfoot impingement, but no osseous abnormalities would be expected at the adjacent lateral talar process (21a)9. Meniscofibular Ligament: Morphology And Functional Significance Of A www.hindawi.com. Epidemiology It is usually a unilateral phenomenon. 1. Sometimes, loose bodies have broken off the osteophytes. This joint's primary movements involve supination, in which the foot rolls toward the body's midline, and pronation, in which the foot rolls away from the midline. Foot Ankle Int. 5-1); the osteophytes were intra-articular.9,10 ODonoghue11 attributed these exostoses to direct osseous impingement during forced dorsiflexion or to post-traumatic calcification. The resulting hindfoot valgus malalignment is one of the components of acquired flatfoot deformity (pes planovalgus), and in severe cases a progressive lateral calcaneal subluxation occurs, such that the calcaneus may contact the fibula during weight-bearing. (Decrease the time that you stand, walk, or engage in exercise that put a load your feet. Marlena Jbara, MD discusses the radiology podiatry toolbox, when the toolbox is indicated in clinical practice, as well as the limitations to those tools. Lateral hindfoot impingement, with extra-articular talocalcaneal impingement and subfibular (calcaneofibular) impingement. However, the capsule of the ankle attaches above the location of the tibial osteophytes and distal to the talar ones. Umans H. Ankle impingement syndromes. You have seven tarsal bones in each foot. A fat-suppressed proton density-weighted image, obtained coronal to the apex of the angle of Gissane in a 54 year-old woman showing normal talocalcaneal alignment, with a normal interval between the lateral malleolar tip and the lateral calcaneus (arrow), and normal position of the peroneal tendons (arrowheads). There are four possible locations of spurs: Anterolateral ankle pain usually is not caused by bony impingement, because the tibia and talus do not come together in this location. Impingement is a clinical syndrome of chronic pain and restricted range of movement caused by compression of abnormal bone or soft tissue within the ankle joint. This type of spur is ideal for arthroscopic treatment. The classification system grades the degree of spur formation and assists in predicting the length of recovery time. The subtalar joint is multi-articular, meaning that it can move in more than one direction. Bilateral posterior ankle impingement syndrome has been described but is rare 5. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. As your body weight shifts forward, the heel prepares to lift from the ground and the foot returns to neutral position. The subtalar joint works with other joints in your foot and ankle to control the movements involved in gait (walking pattern) and other motions. The subtalar joint is vital to mobility. Avoid x-rays in pregnancy, . Lower Saxony has a natural boundary in the north in the North Sea and the lower and middle reaches of the River Elbe, although parts of the city of Hamburg lie south of the Elbe.The state and city of Bremen is an enclave entirely surrounded by Lower Saxony. Conventional magnetic resonance imaging (MRI) accurately detects and localizes anterior tibiotalar spurs, adjacent reactive synovitis and fibrosis, subchondral bone edema, and other coexisting lesions, such as collateral ligament complex injury, osteochondral lesions of the talus, or intra-articular bodies. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. The sagittal T1-weighted image demonstrates extra-articular subcortical cystic changes and bone marrow edema at the lateral talar process and the adjacent calcaneus (arrowheads). [2] Contents 1 Structure 1.1 Ligaments and membranes 2 Function 3 Pathology 4 References The anesthesia is usually general or spinal. To obtain the proper anti-inflammatory effect, you must maintain this dosing pattern for at least 10 days. B, Articular grooving from the loose body. 193: 672-678 http://www.ajronline.org/content/193/3/672.full (full text), 3 MRI of Ankle and Lateral Hindfoot Impingement Syndromes. Call us @ 7026-200-200 Medfin.in for more help The treatment for anterior impingement in the ankle can include physical therapy to help improve the range of motion and break down scar tissue, anti-inflammatory medications to relieve pain and swelling, and ultimately surgery to remove the tissue or bone that is causing the blockage. To the southeast, the state border runs . With progressive collapse of the longitudinal arch and development of a hindfoot valgus deformity, lateral foot pain develops, found to frequently relate to extra-articular talocalcaneal or calcaneofibular impingement1. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. However it now is recognised that all the ankle impingement syndromes can exist on their own or in combination with injuries such as chondromalacia and tendinopathy. The MR imaging findings, along with the appropriate clinical history, can be used to direct arthroscopic examination and subsequent debridement of anterolateral impingement of the ankle. Recovery takes 4-12 months. Anterior impingement syndrome of the ankle is the most common cause of anterior ankle pain in many sports participants. The typical patient is a young athlete presenting with chronic anterior ankle pain. Impingement lesions can also involve structures other than the rotator cuff that lie in the impingement zone, such as the biceps tendon and the subacromial bursa. In plantar flexion, bony impingement occurs posterolaterally between the os calcis and the posterior lip of the tibia. The state government consists of a team of ministers headed by the Minister President. Arthroscopic surgery may be needed to clean out damaged tissue if conservative treatment fails. On the left a lateral view of the ankle shows the normal space between the lateral talar process (asterisk) and the calcaneal angle of Gissane (arrowhead). 1. Glossary of terms for musculoskeletal radiology. Donovan A, Rosenberg ZS. of weight bearing First MTP joint Hallux rigidus Hallux valgus First MTT joint Talonavicular joint Dorsal talar beak (coalition vs. DJD) . The anteromedial spur often can be palpated on physical examination but usually cannot be visualized on standard anteroposterior and lateral radiographs of the ankle. Also frequently present are cystic changes at the bone marrow at these same locations, and subcortical sclerosis at bony contact surfaces. Patients complain of pain along the anteromedial joint line that is aggravated by walking or sporting activities. It also discusses several injuries and chronic conditions that can affect this joint, along with how they are treated. The main ligament that attaches these bones is called the interosseous talocalcaneal ligament, which runs along a groove between them. 1 Talocalcaneal and subfibular impingement in symptomatic flatfoot in adults. The actual angle measurement is not critical and indeed typically remains normal in hindfoot impingement cases. On physical examination, the anteromedial aspect of the ankle appears swollen and is tender to palpation over the anterior tibiotalar fascicle of the deltoid ligament. Vasileff WK, Moutzouros V. Unrecognized pediatric partial Achilles tendon injury followed by traumatic completion: a case report and literature review. Ogilvie-Harris and colleagues20 described an average of 39 months follow-up for patients who were treated for anterior ankle impingement by arthroscopic removal of bony spurs. On physical examination, patients had isolated point tenderness on the anterolateral aspect of the talar dome and in the AITFL, a popping sensation, and aggravation of pain with dorsiflexion and eversion, all of which suggest the diagnosis. AJR Am J Roentgenol. The calcaneofibular ligament may become entrapped in calcaneofibular impingement, as it courses from the fibula to the calcaneus (17a). Hindfoot valgus on MRI has been graded as mild (7-16), moderate (17-26), and severe (> 26), with normal at 0-6 degrees2. The subtalar joint is key to such motions as walking and running, as well as your posture while performing them. Note the absence of signs of osteoarthritis at the adjacent posterior subtalar joint. The success rate is about 80%. The fee is currently $275. As the MR was not obtained during weight-bearing, the measurement may underestimate the extent of functional malalignment. 2001 Mar;22(3):241-6. http://www.ncbi.nlm.nih.gov/pubmed/11310867?dopt=Abstract, 8 Tarsal sinus: arthrographic, MR imaging, MR arthrographic and pathologic findings in cadavers and retrospective study data in patients with sinus tarsi syndrome. A arthroscopic shave and burr were used to remove any scar soft tissue and tibial and talar osteophytes. Physical therapy to help strengthen surrounding muscles, improve joint range of motion and general lower extremity flexibility and balance. Clinical History: A 52 year-old man presents with history of 10 years of right ankle pain, and clinical suspicion of subtalar arthritis. Unable to process the form. In a cadaver study, Tol and colleagues15 described medially located talar osteophytes and anteromedial tibial osteophytes that were up to 7.3 mm in diameter, originated from the anteromedial border, and could remain undetected due to overprojection or superposition of the lateral part of the talar neck and body and the prominent anterolateral border of the distal tibia, respectively.15, These osteophytes are easy to miss (i.e., hidden spurs). 1 It is a thickened distal fascicle of the anteroinferior tibiofibular ligament (AITFL) that extends far distally on the lateral malleolus. , qr 1 . Peroneal tendon subluxation or dislocation has been reported in association with more severe cases of lateral hindfoot impingement2 (16a), leading to tenosynovitis and tendinosis with possible longitudinal split tears or complete tendon tears. Avoid standing or walking barefoot or in unsupportive footwear like slippers or sandals. Alternatively, rearfoot fusions such as triple arthrodesis may be required to realign and provide pain-free stability10. Their findings included capsular and synovial soft tissue thickening anterior to the tibiotalar ligaments and associated osseous abnormalities such as anteromedial osteophytes.25 The impingement is thought to be soft tissue entrapment associated with previous injury to the anterior tibiotalar fascicle of the deltoid ligament complex. The sagittal T2-weighted image with fat saturation shows extra-articular subcortical cystic changes and bone marrow edema at the lateral talar process and the adjacent calcaneus (arrowheads). Spurs often occur on both sides of the joint. 2. 1997;25:737-745. Damage to the subtalar joint can occur for many reasons, including: Osteoarthritis: Also known as age-related or wear-and-tear arthritis. With valgus malalignment the calcaneus may sublux and rotate laterally, resulting in direct osseous contact with the fibula. Ankle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft-tissue or osseous abnormality affecting the tibiotalar joint or extraarticular soft tissues. These include: Treatment can vary by the disorder diagnosed and the underlying cause. Fundamentals of. Narrowing of the posterior talo-calcaneal joint space. 4. The two common causes of impingement are Bassetts ligament and synovial impingement. Arthritis may be treated with oral or injected anti-inflammatory medications (including corticosteroids), while rheumatic causes may benefit from immune-suppressive therapies. The goal of surgery is removal the osteophytes to restore the anterior space and to reduce the chance of symptoms recurring. The impingement can be found in all quadrants around the ankle: anterior, lateral, posterior, and medial. A T1-weighted sagittal image in a 52 year-old male with ankle pain and swelling shows features characteristic of sinus tarsi syndrome, with absence of fat signal at the sinus tarsi (arrow). Several conditions can mimic the anterior impingement syndrome, including osteochondritis dissecans of the talus, a high ankle sprain involving the anterior tibiofibular ligament. The foot begins to pronate immediately after heel strike, as the outer portion of the heel and the rest of the foot makes contact with the ground. They usually have occurred in athletes whose sports necessitated sudden acceleration, jumping, and extremes of dorsiflexion or plantar flexion. ANKLE IMPINGEMENT RADIOLOGY ANTERIOR X-RAY DISCUSSION FINDINGS OF ANTERIOR ANKLE IMPINGEMENT ANTERIOR ANKLE IMPINGEMENT RADIOLOGY WHAT'S THE Dx: ANKLE IMPINGEMENT RADIOLOGY ANTERIOR X-RAY Dr Ravi Radiology Education Asia: radedasia If your Browser is blocking the video, Please view it on our YouTube Channel HERE. The following is the recommended option: green Superfeet. ankle impingement is defined as entrapment of an anatomic structure that leads to pain and decreased range of motion of the ankle, and can be classified as either soft tissue or osseous. Radiology and pathology form a continuum of visualization Fibrosis results in reduced lung volumes . Most commonly, the mechanism that causes the repetitive jamming is a foot that pronates excessively (a foot where the arch flattens and rolls in as the heel rolls out). Verywell Health's content is for informational and educational purposes only. Treatment often requires surgery to realign and stabilize the hindfoot. In 1992, Scranton and McDermott8 classified four types of anterior ankle impingement by the radiographic appearance of bony spurs (Table 5-1). About 15% are better, but still have some problems. Controversy exists about the cause of bony osteophytes around the ankle with normal articular cartilage. The weight-bearing lateral view with the ankle in maximal dorsiflexion (i.e., pli view) demonstrates anterior impingement, and this view commonly is used in evaluating dancers. Schweitzer ME, Karasic D. The foot. A fat-suppressed T2-weighted image in a 52 year-old patient with lateral hindfoot impingement demonstrates characteristic bone marrow edema at the inferior apex of the lateral talar process (asterisk) as well as at the subjacent angle of Gissane (arrowhead). The source of the pain is the joint below the ankle joint, called the subtalar joint. If all modalities of conservative treatment are unsuccessful, operative treatment may be indicated. The subtalar joint may refer to one or two articulations:. Recurrent forced dorsiflexion of the ankle is the main factor in the development of spurs.13,14 Another factor is recurrent microtrauma, and it has been demonstrated that spur formation is related to recurrent ball impacts in soccer players.15 The entire process of spur formation and hypertrophied synovium or fibrosis is exacerbated by recurrent ankle sprains and persistent ankle instability. A posterior coronal view demonstrates that severe heel valgus is present, with an abnormal, 40 degree angle between the medial calcaneal cortex and the long axis of the tibia, measured just posterior to the sustentaculum at the level of the posterior talus and tibia. Rotator Cuff Disease Impingement Arthritis Adhesive Capsulitis Cervical Spine Referred Pain . ISBN 978-3-319-75655-4 ISBN 978-3-319 . Contact Us, Advice Nurses are available 24 hours a day, 7 days a week. Buy Membership for Orthopaedics Category to continue reading. This type is more difficult to treat with the arthroscopy alone because osteophytes often are within the capsular insertion on the neck of the talus. Normal fat signal is seen at the sinus tarsi (long arrow). MRI of anterolateral ankle impingement Share Watch on This subluxation causes a change in the overall shape of the foot, with flattening of the longitudinal arch, valgus of the hindfoot, and abduction of the forefoot6. Two anterior portals were utilised; anetermedial and anterolateral. In supination injury, damage to the anterior nonweight-bearing cartilage rim occurs. A below-knee cast is used for 3 months. It is essential to properly support your foot if this condition is to resolve. After the spur is formed, it may alter normal mechanics or motion of the ankle. Posterior ankle impingement (PAI) syndrome is one of the impingement syndromes involving the ankle. This is known as bone marrow edema (BME) or bone bruise (Fig. The subtalar joint, also known as the talocalcaneal joint, forms a bridge between the foot and ankle. Anteromedial Impingement: Hypothesized etiology includes: inversion ankle sprains; repetitive dorsiflexion resulting in spurs; repetitive capsular traction causing the formation of osteophytes, and chronic microtrauma to the anterior joint area. The location of the bone marrow edema is characteristic, at the extra-articular region at the inferior apex of the lateral talar process and at the immediately subjacent aspect of the calcaneus at the apex of the angle of Gissane (12a). Standard lateral radiographs of the ankle usually show spurs. More severe injuries or deformities may require arthroscopic or open surgery. Donovan A, Rosenberg ZS. A distally inserting fascicle is identified on the fibula, close to the origin of the ATFL on the fibula. The mechanisms behind how the subtalar joint propels you are complex. The relative frequency of lateral hindfoot impingement, or the severity of hindfoot deformity required before the impingement occurs, are not known1. 1 In this chapter, common and unusual pathologic processes of the subtalar joint, their arthroscopic treatment, and results are discussed. the anatomic subtalar joint, i.e. Osteophytic formations occur with weight-bearing articular cartilage damage, such as osteoarthritis of the hip and knee, and occur without weight-bearing articular cartilage damage, such as bony impingement lesions.8. 3. The gait cycle is what happens to the foot and ankle from the time the heel first strikes the ground to the point at which the same heel strikes the ground again. A sagittal T1-weighted image of the ankle in a 54 year-old woman demonstrates normal talocalcaneal alignment, with a normal small interval between the apex of the lateral talar process and the calcaneus at apex of the angle of Gissane (blue lines). ous costal cartilage graft (ACCG) to restore femoral head congruity after lesion debridement. It occurs at the meeting point of the talus and the calcaneus . The anteromedial meniscoid lesion can appear isolated or arising from a partially torn deep deltoid ligament. Pre- and postoperative objective scores were compared. [mri : ] . Thank you, {{form.email}}, for signing up. Oluseun Olufade, MD, is a board-certified orthopedist. Subtalar instability is often treated with corrective orthotics and over-the-counter anti-inflammatory drugs. Rarely a hindfoot deformity with lateral bony impingement may result from prior displaced hindfoot fracture (20a). B, Joint space narrowing with osteophytes (Scranton type IV, Van Dijk grade II). At an earlier stage, physical therapy with Achilles tendon stretching may be warranted in cases of symptomatic flexible flatfoot. great radiopaedia.org. There is peroneal tendinosis (blue arrow), and edema at interposed lateral soft tissues. Conservative treatment is preferred for at least 6 months before operative intervention is considered. The problem has also been referred to as sinus tarsi syndrome.

If excessive, this can result in subtalar pathology including degenerative arthritis, sinus tarsi syndrome, or extra-articular bony contact as with lateral hindfoot impingement. Key points. Request PDF | Ankle bone morphology affects the size of non-trauma related osteochondral lesions of the talus in skeletally immature children | Background This study aimed to elucidate the . Autoimmune diseases: Examples include lupus and rheumatoid . traumatic soft tissue impingement (n=4), osteochondral lesion of the talus (n=4), inflammatory arthritis (n=4), Subtalar joint | Radiology Reference Article | Radiopaedia.org . Patients with subtalar impingement syndrome will often complain of pain with walking, running, or other weight-bearing activities that are felt in an area just below and in front of the ankle bone on the outer side of the ankle (called the sinus tarsi). Anteriorly, the sinus tarsi extends to the margin of the talocalcaneal (anterior subtalar) joint, and medially it extends to the middle facet of the subtalar joint. Content is reviewed before publication and upon substantial updates. They result from injury to the deltoid ligament complex, leading to scar formation and synovitis along the anteromedial joint line. FIGURE 5-2 Anteromedial osteophytes of the tibia and the talus. Excellent or good results were obtained for 100% of patients without osteoarthritis, 77% of patients with grade I disease, and 53% of patients with grade II diseases according to the classification for osteoarthritis of the ankle (see Table 5-2).22 Osteophytes recurred in two thirds of the ankles with grade I osteoarthritis, but the recurrence of osteophytes did not correlate statistically with the return of symptoms. In supination injury, damage to the anterior nonweight-bearing cartilage rim occurs.12 The cartilage proliferation, scar tissue formation, and calcification that may result from attempted repair depend on the degree of initial damage and on chondral and bone cell stimulation. Anterior tibiotalar spurs: a comparison of open versus arthroscopic dbridement. Posterior ankle impingement syndrome. Patients usually present with a sharp pain at the back of the ankle upon plantar flexion. Van Dijk and colleagues12 attributed the osteophytes to medial impingement from inversion of the talus onto the medial tibia and thought they might be related to instability (Fig. A sagittal fat-suppressed T2-weighted image in 70 year-old woman with clinical symptoms of posterior tibial tendon insufficiency and lateral hindfoot pain, shows extra-articular distribution of bone marrow edema at lateral talar process (arrow), with a small flat facet at the distal apex, and with subcortical calcaneal bone marrow edema extending anteriorly (arrowhead). An axial T2-weighted image in 60 year-old male with symptomatic lateral hindfoot impingement including calcaneofibular impingement, also with lateral dislocation of the peroneal tendons which are located lateral to the most distal aspect of the fibula (blue arrow). Given the importance of your subtalar joint and the likelihood of foot pain, it's wise to work on improving your foot joint's strength and movement as much as you can, even if you are young or don't have foot pain. A 3D representation of the normal appearance of the structures involved with lateral hindfoot impingement. Practice Locations UCHealth University of Colorado Hospital (UCH) 12605 E. 16th Ave Aurora, CO 80045 720-848-0000 UCHealth Radiology - Inverness 175 Inverness Drive West Suite 150 Englewood, CO 80112 720-516-1002 Specialty Information Specialties Diagnostic, Board Certification Subluxation at the talocalcaneal joint has been shown to occur in symptomatic adults with acquired flat foot, involving a lateral translocation of the calcaneus into valgus malalignment, with the subluxation greater at the anterior and middle talocalcaneal articular facets than at the posterior facet, leading to reduction of articular contact surfaces at these joints6. Tests can also be used to differentiate subtalar joint disorders from other conditions that cause pain or inflammation in the ankle and heel area. This type is common and is the most difficult to deal with. Stripping off the capsule distally is necessary to visualize the pathology. . Recommended therapy for lateral hindfoot impingement usually involves surgery, due to the difficulty to stabilize a valgus deformity of the hindfoot with conservative measures such as medial wedge inlays or orthotics. The subtalar joint separates the heel bone (calcaneus) from the bone that rocks up and down within the ankle joint (talus). impingement syndromes involving the ankle, Posterior ankle impingement (PAI) syndrome, fracture involving lateral tubercle of the posterior process of the talus, prominent superior surface of calcaneal tuberosity, prominent downslope of the posterior tibial articular surface, any abnormal calcification/ossification posterior to the ankle, may demonstrate posterolateral capsular thickening and synovitis involving an intact, may show one or more of the predisposing anatomical factors, accompanying bone contusion may be present, involving the lateral tubercle of the posterior talar process, localized fluid and/or edema in the posterior joint recesses.
