Department of Orthopedics, University of Miami Miller School of Medicine, Miami, FL It usually occurs following a sprain injury or repetitive microtrauma causing haemorrhage, synovial hyperplasia, and abnormal soft tissue interposition within the joint. Finally, marked deformity associated with arthritis and fixed osseous deformity are best managed with arthrodesis. MRI has been used to evaluate both the subacute stage (i.e., within 4 weeks of the participating injury) and the chronic stage (i.e., 1452 weeks after injury) of posteromedial impingement [20, 48] (Fig. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. 1A, 1B).

Levin, James K. DeOrio. Introduction Pain localized to the lateral subtalar region is often clinically felt to represent either subtalar joint degeneration or sinus tarsi syndrome. More than 8,800 employees, volunteers, health care providers and other personnel working together to create healthy communities and provide award-winning high-quality care for the 938,000 residents in our 25-county service area. The treatment for anterior impingement in the ankle can include physical therapy to . Lateral ankle pain may develop because of lateral hindfoot impingement. Os subfibulare is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle and is rarely reported 1. An additional imaging feature, seen more commonly in patients with clinical anterolateral impingement, includes the absence of the recess between the anterolateral soft tissues and the anterior surface of the fibula despite adequate joint distention with contrast material [25]. Surgical Technique for Management of Severe Calcaneofibular Impingement: Case Series:. Welcome to MyMichigan Health. This accessory, or distal, fascicle is separated from the anteroinferior tibiofibular ligament by a fibrofatty septum (Fig. Together they form a unique fingerprint. Scarring, synovitis, and capsular and anterior deltoid thickening (Fig. Ultrasound has been shown to correlate well with arthroscopic findings in its ability to detect soft-tissue abnormalities including a synovial mass or capsular nodularity in the anterolateral gutter [19]. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. ;Aiyer, Amiethab Interobserver agreement and accuracy, sensitivity, and specificity in the detection of fibular periostitis, peroneal .

(2009) AJR. Role of imaging and imaging features Conventional radiographs may show periosteal new bone formation along the posteromedial wall of the talus and along the medial malleolus [5]. In this review, we describe the pathophysiology, clinical presentation, and imaging features of ankle impingement syndromes and extraarticular impingement syndromes with a focus on MRI findings. This can include talocalcaneal, calcaneofibular (subfibular)or combined talocalcaneal-subfibular impingements. 3. Ankle impingement, typically secondary to an ankle sprain, is classified according to its anatomic relationship to the tibiotalar joint as anterolateral [2], anterior [3], anteromedial [4], posteromedial [5], or posterior [6] impingement. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot.

Sagittal T1-weighted images may show secondary displacement of normal fat anterior to the fibula by the presence of syno vitis or scar tissue [26]. (2019). subfibular impingement, Affiliations: Donovan A, Rosenberg ZS. Some of these abnormalities may coexist with anterolateral impingement and may lead to persistent pain despite surgical resection of the tissues causing impingement. 5A, 5B). The frequency of subfibular impingement was also statistically higher in the group with periostitis than in the group without it (p < .001). Interventional radiology is a fast-growing medical specialty recognized by the American Board of Medical Specialties. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. The accessory anteroinferior tibiofibular ligament may normally contact the anterolateral corner of the talus. These patients include those with isolated posteromedial synovitis and no associated chondral injury or ligament instability. The radiologist must recognize, however, that MRI features supportive of impingement may not necessarily be the cause of the patient's pain and that accurate diagnosis requires careful correlation with the clinical picture and, if necessary, dynamic ultrasound for confirmation. MRI often is necessary to rule out other causes of ankle pain. Orthopaedic Specialty Institute, Orange, CA Less frequent findings include fibular tip marrow edema and contact between the fibula and calcaneus, occasionally with the formation of a neocalcaneal facet (Fig. 469-474, 10.1148/radiol.12111066. Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [ 12 ]. Anterolateral Impingement (Ankle) 6 min. Ankle impingement syndromes are important causes of persistent ankle pain after an ankle sprain.

Patients usually present after the development of significant soft-tissue abnormality such as synovial thickening along the posterior capsule or thickening of the posterior intermalleolar or talofibular ligaments [52, 54]. Lateral talocalcaneal and subfibular impingements were defined as signal and morphologic alterations or direct contact at the opposing surfaces of the lateral talus and calcaneus and at the fibula and calcaneus, respectively. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is typically associated with pes planovalgus resulting from posterior tibial tendon dysfunction or calcaneal fracture malunion.. How do you treat ankle impingement? Pathophysiology and clinical features Anterior ankle impingement syndrome is a common cause of chronic ankle pain, especially in ballet dancers and soccer players [31, 32]. Glenohumeral Joint, Wrist and Ankle Plica. On MR arthrography, anteromedial capsular thickening and abnormal soft tissue anterior to the tibiotalar ligament and medial malleolus are best seen on axial images, whereas both the axial and sagittal planes are helpful in assessing anteromedial osteophytes [4]. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. It is classically described in ballet dancers. Advanced imaging findings are related to abutment between the fibula and calcaneus and . Additionally, MRI is valuable in the detection of extraarticular, lateral hindfoot impingements in patients with hindfoot valgus deformity. Patients usually present with posteromedial point tenderness and pain between the medial wall of the talus and the posterior margin of the medial malleolus [5, 20]. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 3 2 Keywords Both conventional MRI and ultrasound are useful for detecting posteromedial impingement [20, 48]. The objective of this article is to review the pathophysiology and clinical presentation of impingement syndromes at the ankle joint (anterolateral, anterior, anteromedial, posteromedial, and posterior) and the role of MRI in evaluating impingement at the ankle joint and at extraarticular locations, lateral to the ankle joint (talocalcaneal and calcaneofibular). Conventional axial T1 and fluid-sensitive images are optimal for detecting the intermediate- to low-signal synovial hypertrophy and scarring in the anterolateral gutter [2125] (Fig. 10A, 10B, 10C). Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. Clinical presentation Note subfibular bone fragment (arrow) possibly leading to subfibular impingement. MRI often is necessary to rule out other causes of ankle pain.

On physical examination, there is focal anteromedial ankle tenderness and swelling with limited dorsiflexion and supination [4, 46]. On physical examination, flatfoot and hindfoot valgus deformity are evaluated with the patient sitting and standing. Posterior impingement, also termed os trigonum syndrome, typically occurs due to a large os trigonum or Stieda process . Coronal CT images have been shown to best depict nodular thickening related to synovial impingement [30]. These impingements are sequelae of flatfoot deformity and hindfoot valgus from a variety of causes such as posterior tibial tendon (PTT) deficiency, rheumatologic disorders, diabetes, calcaneal fractures, and congenital flatfoot [7, 8]. ;Buller, Leonard T. author = "Kaplan, {Jonathan R.M.} Results: Twenty-eight cases (37%) of lateral hindfoot impingement were identified, including six talocalcaneal, eight subfibular, and 14 talocalcaneal-subfibular impingements.

Compression causing subsequent hypertrophic changes and fibrosis of the posteromedial tibiotalar capsule and posterior deltoid fibersspecifically, those of the posterior tibiotalar ligament between the talus and medial malleolusis suggested as the inciting event for posteromedial impingement [5]. The most common symptoms include pain and tenderness along the posterior ankle that is exacerbated on plantar flexion or dorsiflexion [6, 55]. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. 3 topics. The most common MRI manifestations of talocalcaneal impingement are cystic changes, sclerosis, and edema in the posterior subtalar joint and in the lateral process of the talus and the lateral calcaneus [10] (Figs. 1 Extra-articular calcaneofibular impingement (EA-CFI), Extra-articular talocalcaneal impingement (EA-TCI), Extraarticular lateral hindfoot impingement syndrome, Extra-articular lateral hindfoot impingement syndrome (ELHIS), additionally, removal of any subfibular or superolateral calcaneal bone causing impingement. 2. Pathophysiology and clinical features Posterior impingement, or so-called os trigonum syndrome, is caused by repetitive plantar flexion leading to compression of bone and soft tissues at the posterior ankle [6, 49, 50].

MRI often is necessary to rule out other causes of ankle pain. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. MRI; 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. Peroneal tendon subluxation (Fig. Extraarticular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. MRI often is necessary to rule out other causes of ankle pain. However, the severity of symptoms is not associated with the presence or size of either of these two structures [6]. Impingement results from abnormal contact laterally as the valgus deformity results in sinus tarsi narrowing, which it does normally during eversion (although to a lesser degree in normal individuals)3. Several normal osseous and soft-tissue anatomic variants predispose individuals to posterior impingement including a prominent os trigonum, a prominent lateral talar process (Stieda process), a shelflike superior prominence of the calcaneal tuberosity, and a posterior intermalleolar ligament [49, 52]. Therefore, detection of impingement with MRI at an early stage may be beneficial [10, 74]. Clinical presentation varies on the basis of the cause of flatfoot and hindfoot valgus. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [12]. Impingement syndrome of left shoulder.

Role of imaging and imaging features Conventional radiographs with the addition of the anteromedial impingement view are helpful in the detection and characterization of spurs and in the visualization of the ankle joint space [43]. Malicky ES, Crary JL, Houghton MJ et al. However, in the setting of a prior ankle sprain, posterolateral ankle laxity leads to anterior extrusion of the talar dome with dorsiflexion, increased pressure at the site of contact, and subsequent synovial hypertrophy and impingement between the anterolateral talus and the accessory anteroinferior tibiofibular ligament [12]. 10A, 10B, 10C and 11A, 11B). title = "Subfibular impingement: Current concepts, imaging findings and management strategies". Role of imaging and imaging featuresIn most cases, conventional, preferably weight-bearing, radiography is the imaging study of choice because anterior impingement is typically related to osseous abnormalities [3, 42]. 5. Surgery for anterolateral impingement is reserved for patients not responding to conservative treatment such as physiotherapy or nonsteroidal antiinflammatory drugs (NSAIDs). 4. It is of paramount importance, however, to remember that MRI features supportive of impingement may be present in asymptomatic individuals and that accurate diagnosis requires careful correlation of imaging features with the clinical picture. Associated findings include thickening of the anterior talofibular ligament.

There may be decreased range of motion of the ankle, hindfoot, midfoot, and forefoot and lateral ankle pain on palpation. ankle impingement; Several mechanisms have been proposed for spur formation along the anterior margin of the joint. A clinical sign that is helpful in differentiating posteromedial impingement and PTT abnormalities is posteromedial tenderness on inversion with the ankle in plantar flexion, which is seen in patients with posteromedial impingement and not in those with PTT abnormalities [5]. The role of MRI in detecting anteromedial impingement has not yet been established [45] (Fig. Although some patients present after an acute injury such as avulsion of the posterior talofibular ligament, disruption of the synchondrosis, or a talar fracture, most patients report insidious development of symptoms related to repetitive athletic activity that requires plantar flexion [6]. or neuropathic or inflammatory arthritidies. MRI features of lateral hindfoot impingement are more commonly seen in patients with advanced PTT tears and with greater MR hindfoot valgus angle [10]. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. Calcaneal osteotomy is often necessary to correct hindfoot valgus and lateral hindfoot impingement [7]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. and Amiethab Aiyer and Nguyen, {Duc M.} and Ettore Vulcano and Buller, {Leonard T.} and Pooja Sheth and Jean Jose". 12A, 12B, 12C).

Dive into the research topics of 'Subfibular impingement: Current concepts, imaging findings and management strategies'. MRI is useful in confirming the diagnosis, evaluating patients with an uncertain clinical diagnosis, and planning surgery. The predominant abnormality detected on MRI is spur formation along the anterior tibial rim, medial lateral malleolus, or talar neck and is often accompanied by synovitis and soft-tissue thickening in the anterior recess (Fig. Syed Ehtasham Junaid, Anil Haldar, Raul Colta, Karan Malhotra, Kar Ho Brian Lee, Matthew Welck, Asif Saifuddin.

Subcortical cyst formation is also prominent within the mid talus and lesser so at the distal fibula with subfibular soft tissue edema. 1A, 1B). In cases of sinus tarsi narrowing, calcaneofibular impingement is unlikely to occur without sinus tarsi impingement. OBJECTIVE. presence of subfibular impingement, and hindfoot valgus angle measurements. Kaplan JRM, Aiyer A, Nguyen DM, Vulcano E, Buller LT, Sheth P et al. Furthermore, overall clinical postsurgical outcome depends on the degree of articular cartilage loss and subchondral marrow abnormality along the remainder of the tibiotalar joint [36]. The MRI features of posteromedial impingement are not specific. 2: It presents as the sequela of a pathological tibialis posterior dysfunction, which can cause pes planus (flatfoot)and hindfoot valgus deformity. In patients unresponsive to conservative therapy, arthroscopic resection of the os trigonum and any associated soft-tissue abnormality can also result in symptom relief and functional improvement [6, 55]. MRI often is necessary to rule out other causes of ankle pain. Regardless of the initial cause of flatfoot, patients with rigid flatfoot deformity experience decreased range of motion at the midfoot and hindfoot and decreased ankle dorsiflexion [72]. Early detection of impingement using MRI may be beneficial for successful surgical results [9, 10]. modify the keyword list to augment your search. Unable to process the form.

For patients unable to undergo an MRI examination, CT arthrography may be useful. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. Up to 14% of the asymptomatic population may have an os trigonum [49]. [37] noted that medially situated anterior talar osseous outgrowths occur intraarticularly, consistent with osteophytes, whereas lateral outgrowths develop extraarticularly, representing enthesophytes from capsular or ligamentous traction [37]. In general, the diagnosis of ankle impingement is clinical, with supporting information provided by radiographs and more advanced imaging (CT, MRI and ultrasound), 3 - 6 which can help further elucidate the anatomic mechanism of impingement, localize pathology to guide diagnostic and therapeutic injections and assist with pre-surgical planning. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. The mechanism is not well understood but is likely a rare complication of a supination (inversion) injury [4, 46] rather than a pronation (eversion) injury as initially hypothesized [45]. MRI, in particular, is also valuable for identifying other causes of persistent ankle pain that may mimic or coexist with ankle impingement, such as occult fractures, cartilage damage, intraarticular bodies, osteochondral talar lesions, tendon abnormalities, and ankle instability [1]. In comparison, anterior osteophyte formation has been attributed to joint abnormalities related to hyperdorsiflexion, microtrauma, ankle instability, and recurrent supination [38, 39]. Bilateral posterior ankle impingement syndrome has been described but is rare 5 . Conservative management is usually successful in most patients with anterior ankle impingement syndrome. Extra-articular lateral hindfoot impingement syndrome. Patients with anteromedial impingement often present with chronic anteromedial pain that is exacerbated by dorsiflexion. 1A, 1B ).

CT facilitates accurate assessment of osseous changes between the os trigonum and talus, such as fragmentation of the os and pressure-related erosions along the talus [49]. MRI can aid in the management of posteromedial impingement by excluding significant concomitant injuries and by identifying patients who may benefit from ultrasoundguided therapeutic injection. Administration of IV gadolinium may improve detection of small focal areas of synovitis surrounding the posterior ligaments [60]. 7A, 7B) may be noted on axial, sagittal, or coronal MRI. Donovan A, Rosenberg ZS. ;Sheth, Pooja There are several causes of lateral hindfoot impingement including PTT dysfunction [67, 68], healed intraarticular calcaneal fractures [69], neuropathic arthropathy [70], and inflammatory arthritides [71]. Arthroscopy and open surgery to remove spurs or soft-tissue abnormalities are effective in patients with no underlying tibiotalar articular disease [3, 34, 36, 40, 41]. Please try after some time.

However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. In patients with chronic posteromedial impingement (1452 weeks after injury), there was a higher incidence of posterior tibiotalar ligament disruption and abnormal signal encasing or abutting the PTT and flexor digitorum longus tendons [48]. The main role of ultrasound is to assist with therapeutic injection of the synchondrosis [56]. doi = "10.1097/BCO.0000000000000702". This condition is most commonly seen in ballet dancers [51] and soccer players [39]. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. A provocative physical examination test in which a physician attempts to pinch hypertrophied synovium between the tibia and the talus has been described. (2017) The British journal of radiology.

CT; Osseous outgrowths at the anterior ankle joint, which are at times asymptomatic, represent a major pathologic component of this impingement syndrome, but soft-tissue impingement due to hypertrophied synovium also occurs [33] (Fig. It is thought to represent a normal variant and may be identified in 2197% of ankles [12, 1416]. Talocalcaneal impingement typically occurs before subfibular or combined talocalcanealsubfibular impingements [9, 10]. Hindfoot valgus (often defined as a tibiocalcaneal angle >11) with one or both of the following 5: Treatment may be non-operative or operative. Arthroscopic dbridement of the impinging soft tissue has been shown to be effective in many patients [11, 18]. Subfibular impingement is one cause of extraarticular ankle . Clinical presentation Os subfibulare are usually asymptomatic although they may eventually cause painful syndromes or degenerative change in response to overuse and trauma. Marrow edema was seen infrequently and had no specific distribution [20]. 69-76(8), DOI: https://doi.org/10.1097/BCO.0000000000000702, Keywords: Conventional weight-bearing ankle radiographs are useful to assess the plantar arch and hindfoot valgus. 4: 1A, 1B). Severe flatfoot and hindfoot valgus deformity may present with lateral ankle pain in the region bounded by the anterior fibula and the sinus tarsi [7]. This can include talocalcaneal, calcaneofibular (subfibular) or combined talocalcaneal-subfibular impingements. The department of radiology provides clinical service to Michigan Medicine, which includes the physically-connected University Hospital, Taubman outpatient center, C.S. Conventional arthrography may confirm disruption at the synchondrosis, evident by contrast material collecting within the synchondrosis, and is an excellent tool for performing a diagnostic or therapeutic injection. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures The ossicle itself may fracture. 7 min. The aim of operative treatment is to correct the hindfoot valgus and includes 4: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. (2020) Foot & Ankle Orthopaedics. CT may be helpful for further characterizing the location and size of the spurs but is rarely indicated [36] (Fig. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. In most patients, ultrasound will show hypoechoic, nodular capsular thickening localized to the lateral aspect of the lateral talar process or the os trigonum. Methods:: Patients with posterior tibial tendonitis were retrospectively searched and reviewed. The other authors have no disclosures. Similar to conventional MRI, this technique is limited by a lack of joint fluid [29]. In patients with impingement that is resistant to conservative therapy, imaging-guided therapeutic injection with a mixture of local anesthetic and steroids offers a rapid return to athletic activity and long-lasting symptom relief [56]. Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. The anatomic boundaries of the anterolateral gutter, a triangular-shaped recess, include the tibia posteromedially; the fibula laterally; and the tibiotalar joint capsule, which is reinforced by the anteroinferior tibiofibular, anterior talofibular, and calcaneofibular ligaments, anteriorly and laterally [12] (Fig. This form of synovitis has been described as a meniscoid lesion [13]. Ligaments of the Transverse Tarsal Joint Complex: MRIAnatomic Correlation in Cadavers. The hindfoot valgus angle was statistically larger in the group with periostitis than in the control group ( p = .01-.002) and among patients with versus those without peroneal tendon subluxation . A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Alternatively, there may be subluxation of the subtalar joint resulting in impingement between the calcaneum and the fibula 4. The Achilles tendon may show contracture and tightness [72]. Role of imaging and imaging features Conventional radiographs can be used to identify the os trigonum and the lateral tubercle of the talus as well as opposing cystic and sclerotic changes along the synchondrosis [57] (Fig. This lateral ankle pain has been attributed to extraarticular lateral hindfoot impingement including talocalcaneal impingement (between the lateral talus and calcaneus) [61] and subfibular impingement (between the calcaneus and fibula) [6264] (Fig. Conventional MRI may play a role in excluding other abnormalities contributing to a patient's symptoms, such as talar osteochondral injuries, but may not be sensitive in detecting subtle capsular changes. With progressive deformity, secondary osteoarthrosis of the subtalar, talonavicular, and calcaneocuboid articulations contribute to pain symptoms [62]. 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. Pathophysiology and clinical features Posteromedial impingement is the least recognized ankle impingement syndrome and is thought to be a sequela of severe inversion injury [47, 48]. As more healthcare continues to . On ultrasound, hypoechoic nodular posteromedial soft-tissue thickening may be seen deep to the PTT, between the medial malleolus and talus. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Search for Similar Articles 14A, 14B). Jonathan R.M. 4 Glenoid Dysplasia: Incidence and Association with Posterior Labral Tears as Evaluated on MRI, Original Research. In patients with advanced synovitis, the synovial tissue may become molded to the triangular shape of the anterolateral gutter. Ankle impingement syndromes are defined as pathologic conditions resulting in chronic, painful restriction to movement at the tibiotalar articulation secondary to soft-tissue or osseous abnormalities [1]. Level of Evidence: Level V. Subfibular impingement : Current concepts, imaging findings and management strategies. We are: A non-profit health system headquartered in Midland, Michigan. Level of Evidence: Level V.". In patients with PTT dysfunction, medial ankle pain is the presenting symptom during the early stages of PTT dysfunction, whereas lateral ankle pain related to hindfoot valgus and lateral impingement predominates in long-standing PTT dysfunction [7]. Healed intra-articular calcaneal fractures, neuropathic arthropathy, and inflammatory arthritides may also play a causative role. Kaplan, J. R. M., Aiyer, A., Nguyen, D. M., Vulcano, E., Buller, L. T., Sheth, P., & Jose, J. Femoroacetabular impingement is an intra-articular or internal form of impingement, where structural changes combined with dynamic factors as repetitive abnormal contact of the acetabulum and the femoral head-neck junction lead to mechanical stress and shear forces on the labrum and chondral surfaces and subsequent damage 1-4. MRI of Ankle and Lateral Hindfoot Impingement Syndromes. Surgical correction of osseous lateral hindfoot impingement related to hindfoot valgus is increasingly being performed [7]. The authors report no conflicts of interest in regard to this work. Pathology. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment Calcaneocuboid joint effusion. publisher = "Lippincott Williams and Wilkins Ltd.", Kaplan, JRM, Aiyer, A, Nguyen, DM, Vulcano, E, Buller, LT, Sheth, P & Jose, J 2019, '. Most patients with posterior impingement respond to conservative management including physiotherapy. Although the initial injury is usually minor and does not result in clinical ankle instability [2], repetitive microtrauma and subclinical microinstability may lead to soft-tissue abnormalities in the anterolateral gutter. As in the assessment of patients with anterolateral impingement, the addition of Doppler ultrasound does not show increased flow within the abnormal soft tissue in patients with posteromedial impingement [19, 20]. 1: Ligamentous and capsular tearing and the resultant microinstability and hemorrhage after an ankle sprain may lead to reactive synovial hyperplasia and scarring in the anterolateral gutter [2] (Fig. Have used weight-bearing CT scans to evaluate subfibular impingement, extraarticular impingement, also os!
