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]. 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. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Extra-articular lateral hindfoot impingement syndrome. Advanced Radiology Services hires the nation's best and brightest board-certified radiologists. The accessory anteroinferior tibiofibular ligament may normally contact the anterolateral corner of the talus. Similar to conventional MRI, this technique is limited by a lack of joint fluid [29]. 15. This condition is most commonly seen in ballet dancers [51] and soccer players [39]. Relief of symptoms after therapeutic injection helps confirm the diagnosis [49]. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Pathophysiology and clinical features Anterolateral impingement is thought to be secondary to an inversion injury resulting in disruption of the syndesmotic and/or lateral collateral ligaments and capsule and is typically seen in young athletic patients [11]. 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]. Icahn School of Medicine at Mount Sinai Home, Subfibular impingement: Current concepts, imaging findings and management strategies, https://doi.org/10.1097/BCO.0000000000000702. 3). In patients with advanced synovitis, the synovial tissue may become molded to the triangular shape of the anterolateral gutter. However, there is no associated ligamentous ankle instability. Patients with anterolateral impingement present with chronic ankle pain, swelling along the anterolateral aspect of the ankle, and limited dorsiflexion. 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]. or extensive soft-tissue thickening between the fibula and the calcaneus. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Calcaneal osteotomy is often necessary to correct hindfoot valgus and lateral hindfoot impingement [7]. Subjects had documented flatfoot deformity, posterior tibial tenderness, weight . 14A, 14B) may be seen more commonly in patients with moderate or severe hindfoot valgus and in those with combined talocalcanealsubfibular impingement. Healed intra-articular calcaneal fractures, neuropathic arthropathy, and inflammatory arthritides may also play a causative role. 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]. Mott Children's Hospital, the von Voigtlander Women's Hospital, Frankel Cardiovascular Center, and Rogel Cancer Center on the main campus. 4: Talocalcaneal and subfibular impingement in symptomatic flatfoot in adults. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Dr. Vulcano discloses a financial relationship with Wright Medical outside this work. 2). It is thought to represent a normal variant and may be identified in 2197% of ankles [12, 1416]. [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]. 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. 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. Production or aggravation of pain during this maneuver, or so-called positive impingement sign, has been shown to be highly sensitive and specific (94.8% and 88%, respectively) for identifying anterolateral impingement [17]. ;Vulcano, Ettore CONCLUSION. MRI of Ankle and Lateral Hindfoot Impingement Syndromes. Early detection of impingement using MRI may be beneficial for successful surgical results [9, 10]. No studies have used weight-bearing CT scans to evaluate subfibular impingement. Surgical correction of osseous lateral hindfoot impingement related to hindfoot valgus is increasingly being performed [7]. The MRI features of posteromedial impingement are not specific. Management focuses on limitation of symptom-provoking activity, such as correction of overpronation in ballet dancers, as well as physiotherapy [31]. Extraarticular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. Entrapment and thickening of the calcaneofibular ligament are also seen (Fig. described for the management of these deforming forces. ARS offers Prostate Artery Embolization, a procedure performed by an Interventional Radiologist and designed to shrink an enlarged prostate thereby improving urinary tract symptoms. Opposing sclerosis and cystic changes may also be seen [7]. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. 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. Direct MR arthrography with intraarticular instillation of contrast agent has been shown to be highly sensitive (97%) and specific (100%) for assessing the anterolateral recess [25]. subfibular impingement, Affiliations: Level of Evidence: Level V. AB - Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. In patients with anterolateral impingement, indirect MR arthrography did not offer additional information compared with conventional MRI [29]. Furthermore, ultrasound can facilitate imaging-guided therapeutic injection of the synovial lesion [20]. Most patients with posterior impingement respond to conservative management including physiotherapy. Additionally, MRI is valuable in the detection of extraarticular, lateral hindfoot impingements in patients with hindfoot valgus deformity. MRI can also aid in assessing other causes for lateral pain in valgus foot such as lateral malleolar bursitis and distal fibular stress fracture. Advanced lateral hindfoot osseous impingement may show direct contact between the talus and calcaneus or between the lateral calcaneus and fibula. 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? MRI often is necessary to rule out other causes of ankle pain. Department of Orthopedics, University of Miami Miller School of Medicine, Miami, FL CT is more sensitive than radiography for identifying cystic and sclerotic changes [9]. 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]. On ultrasound, hypoechoic nodular posteromedial soft-tissue thickening may be seen deep to the PTT, between the medial malleolus and talus. T2 - Current concepts, imaging findings and management strategies. 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. Acute synovitis is treated with rest and NSAIDs to reduce inflammation. Glenoid Dysplasia: Incidence and Association with Posterior Labral Tears as Evaluated on MRI, Original Research.

Os subfibulare is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle and is rarely reported 1. extraarticular impingement; 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]. Kaplan, Jonathan R.M. On physical examination, there is posterior ankle tenderness and occasionally there may be palpable soft-tissue thickening anterior to, but not involving, the Achilles tendon [6]. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. Current Orthopaedic Practice30(1):69-76, January/February 2019. Both conventional MRI and ultrasound are useful for detecting posteromedial impingement [20, 48]. 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]. Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [12]. MRI is useful in confirming the diagnosis, evaluating patients with an uncertain clinical diagnosis, and planning surgery. American Journal of Radiology, September 2010, Vol. MRI often is necessary to rule out other causes of ankle pain. The other authors have no disclosures. Together they form a unique fingerprint. Glenohumeral Joint, Wrist and Ankle Plica. 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. One of the important roles of MRI is also to assess a patient for other pathologic conditions that can mimic or coexist with impingement syndromes such as chondral defects and ligament disruption. 2: Marrow edema is uncommonly seen with anterior ankle impingement [29, 44]. Arthroscopic dbridement of the impinging soft tissue has been shown to be effective in many patients [11, 18]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. The extent of arthro desis should be limited to minimize the stress transfer to proximal and distal joints [72]. ;Jose, Jean 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.

Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Hindfoot valgus (often defined as a tibiocalcaneal angle >11) with one or both of the following 5: Treatment may be non-operative or operative. MRI showed increased signal in the posteromedial capsule in four of nine subacute cases, increased signal in the posterior tibiotalar ligament in nine of nine cases, displacement of the PTT and flexor digitorum longus tendons in seven cases, and disruption of the posterior tibiotalar ligament fibers in four cases [20]. Less frequent findings include fibular tip marrow edema and contact between the fibula and calcaneus, occasionally with the formation of a neocalcaneal facet (Fig. 2. 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. abstract = "Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot.

Epidemiology It is usually a unilateral phenomenon. 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]. The goal of conservative treatment early in the course of the disease is to prevent further disability and progressive deformity. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, /. 3 N2 - Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 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]. 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. By continuing to use this website you are giving consent to cookies being used.

The radiographic finding of fibular tip periostitis in patients with hindfoot valgus can be a predictor of peroneal tendon subluxation-dislocation and may also suggest advanced hindfoot valgus and subfibular impingement. Imaging features of subfibular impingement often include extensive lateral soft-tissue thickening between the fibula and the calcaneus (Fig. MRI may be useful in examining patients in whom coexistent abnormalities are suspected clinically [29]. View Record in Scopus Google Scholar. The authors report no conflicts of interest in regard to this work. 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. 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. Pathophysiology and clinical features Anteromedial impingement is a relatively rare ankle impingement [45]. The main differential diagnosis for postero medial ankle pain includes PTT abnormalities. 1A, 1B ). Several mechanisms have been proposed for spur formation along the anterior margin of the joint. Surgical Technique for Management of Severe Calcaneofibular Impingement: Case Series:.

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]. Furthermore, mild posteromedial synovitis was present in two control subjects [20]. In most patients, ultrasound will show hypoechoic, nodular capsular thickening localized to the lateral aspect of the lateral talar process or the os trigonum. 50 (7): 1317. The addition of Doppler assessment has not been shown to be helpful [19]. 7 min. Role of MRI and imaging featuresThe role of MRI in evaluating anterolateral impingement is to exclude abnormalities other than soft-tissue impingement and to assess patients with an uncertain clinical diagnosis. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. 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]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Ultrasound is helpful in guiding therapeutic injection of the posteromedial synovial mass in select patients with no associated osteochondral abnormality or joint instability [20]. Surgical strategies for the treatment of posteromedial impingement include dbride ment of abnormal soft tissue from the postero medial corner. 672-678. keywords = "CT, MRI, ankle impingement, extraarticular impingement, foot and ankle surgery, lateral hindfoot impingement, sports medicine, subfibular impingement". 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]. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. The responsibility for the publication content rests with the publishers providing the material. MRI features of lateral hindfoot impingement are more commonly seen in patients with advanced PTT tears and with greater MR hindfoot valgus angle [10]. 3 min. 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]. title = "Subfibular impingement: Current concepts, imaging findings and management strategies". Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. Kaplan, Jonathan R.M. 4A, 4B). @article{573babf591204f73998be74cfa79bf3d. In comparison, anterior osteophyte formation has been attributed to joint abnormalities related to hyperdorsiflexion, microtrauma, ankle instability, and recurrent supination [38, 39]. 193 (3): 672-8. Patients with anteromedial impingement often present with chronic anteromedial pain that is exacerbated by dorsiflexion. Bilateral posterior ankle impingement syndrome has been described but is rare 5 . 2 4A, 4B). Ankle impingement syndromes are important causes of persistent ankle pain after an ankle sprain. Kaplan, MD, Articles in Google Scholar by Jonathan R.M. 13A, 13B, 13C and 14A, 14B). 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 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. 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. Results: Twenty-eight cases (37%) of lateral hindfoot impingement were identified, including six talocalcaneal, eight subfibular, and 14 talocalcaneal-subfibular impingements. Kaplan JRM, Aiyer A, Nguyen DM, Vulcano E, Buller LT, Sheth P et al. On physical examination, there is focal anteromedial ankle tenderness and swelling with limited dorsiflexion and supination [4, 46]. MRI; 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].

Berman Z, Tafur M, Ahmed SS, Huang BK, Chang EY. 4 Ankle impingement syndromes: an imaging review. 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]. The most common symptoms include pain and tenderness along the posterior ankle that is exacerbated on plantar flexion or dorsiflexion [6, 55]. MRI often is necessary to rule out other causes of ankle pain. OBJECTIVE. MRI often is necessary to rule out other causes of ankle pain. 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]. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 3: Note subfibular bone fragment (arrow) possibly leading to subfibular impingement. 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). 1 Department of Radiology, Musculoskeletal Division, NYU Langone Orthopedic Hospital, NYU Langone Health, 301 E 17th St, 6th Fl, New York, NY 10003. .

Radiographs enable evaluation of the spurs and the tibiotalar joint space, both of which are important for diagnosis and preoperative planning (Fig. Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. However, routine MRI was found to be more accurate in detecting thickened, nonenhancing scar and in the setting of a joint effusion [28]. This form of synovitis has been described as a meniscoid lesion [13]. Unable to process the form.

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. 3 topics. Surgery for anterolateral impingement is reserved for patients not responding to conservative treatment such as physiotherapy or nonsteroidal antiinflammatory drugs (NSAIDs). It presents as the sequela of a pathological tibialis posterior dysfunction, which can cause pes planus (flatfoot)and hindfoot valgus deformity. The efficacy of conventional nonarthrographic MRI to detect anterolateral gutter soft-tissue abnormalities remains controversial, with a wide range of sensitivities (39100%) and specificities (50100%) [2123], and has been shown to be accurate in detecting only substantial joint effusions [24]. American journal of roentgenology. 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]. Marrow edema was seen infrequently and had no specific distribution [20]. 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]. Administration of IV gadolinium may improve detection of small focal areas of synovitis surrounding the posterior ligaments [60]. Some of these abnormalities may coexist with anterolateral impingement and may lead to persistent pain despite surgical resection of the tissues causing impingement. What causes Subfibular impingement? ;Nguyen, Duc M. Finally, marked deformity associated with arthritis and fixed osseous deformity are best managed with arthrodesis. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. 6A, 6B). 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. 1A, 1B).

Associated with severe hindfoot deformity, subfibular. 9). foot and ankle surgery; 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]. The ossicle itself may fracture. Kaplan, Amiethab Aiyer, Duc M. Nguyen, Ettore Vulcano, Leonard T. Buller, Pooja Sheth, Jean Jose, Research output: Contribution to journal Review article peer-review. 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. Furthermore, abrasion of the anterolateral talar dome articular surface and secondary chondral injury may develop [15]. FEATURED PROVIDER. 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]. A superimposed rotational mechanism and repeated microtrauma lead to anteromedial capsular thickening and synovitis in the region of the anterior tibiotalar ligament of the deltoid complex [4]. The treatment for anterior impingement in the ankle can include physical therapy to . Talocalcaneal impingement typically occurs before subfibular or combined talocalcanealsubfibular impingements [9, 10]. Coronal CT images have been shown to best depict nodular thickening related to synovial impingement [30]. Unlike anterolateral impingement, osteophytes are an important feature of anteromedial impingement [4]. Similar to other types of ankle impingement, Doppler evaluation does not show increased flow within the abnormal soft tissues. Ingenta is not the publisher of the publication content on this website. Wolters Kluwer Health, Inc. and/or its subsidiaries. 3. Level of Evidence: Level V.". These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. 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]. 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]. Keywords Indirect MR arthrography is a noninvasive alternative to direct MR arthrography, which requires IV administration of contrast material followed by 20 minutes of joint exercise. doi = "10.1097/BCO.0000000000000702".

MRI often is necessary to rule out other causes of ankle pain. sports medicine; 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. Subcortical cyst formation is also prominent within the mid talus and lesser so at the distal fibula with subfibular soft tissue edema. Pathology Etiology Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. 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]. Subfibular impingement is one cause of extraarticular ankle . Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. Donovan A, Rosenberg ZS. 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. 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. presence of subfibular impingement, and hindfoot valgus angle measurements. Conventional MRI can accurately detect abnormalities at the synchondrosis including opposing marrow edema or fluid signal at the synchondrosis related to motion [49, 50, 59] (Fig. In patients with advanced PTT dysfunction, soft-tissue balancing procedures alone are inadequate for restoring the longitudinal arch [73]. Repetitive kicking in plantar flexion has been postulated to lead to traction on the anterior capsule and enthesophyte formation [37]. 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]. 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.

Soft-tissue abnormalities at the posterior ankle such as posterior capsular thickening, ligament disruption, FHL tenosynovitis, and soft-tissue edema and synovitis can also be well depicted by MRI [49, 50, 60] (Figs. Posteromedial abnormalities were present in all patients with a clinical diagnosis of posteromedial impingement, but posterior and posterolateral synovitis were also seen in these patients [20]. It remains unclear whether this is primarily due to bony or soft-tissue impingement. Contrast-enhanced fat-suppressed 3D fast gradient-recalled MR acquisition in the steady state with radiofrequency spoiling has been shown to be highly sensitive, although not very specific and accurate, for depicting enhancing vascularized synovial tissue in the anterolateral gutter [27]. Thus, it is thought that impingement occurs laterally first through the sinus tarsi and then progresses to the calcaneofibular interval 3. MRI is valuable in assessing both osseous and soft-tissue abnormalities associated with impingement syndromes. ; Aiyer, Amiethab ; Nguyen, Duc M. et al. Website 2022 Ingenta. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. 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]. On physical examination, flatfoot and hindfoot valgus deformity are evaluated with the patient sitting and standing. Anteromedial tibial and talar osteophytes are not always detected on lateral radiographs, and additional oblique anteromedial impingement radiographs may be required [43]. These patients include those with isolated posteromedial synovitis and no associated chondral injury or ligament instability. Keywords: ankle impingement, calcaneofibular impingement, extraarticular impingement, MRI, sports medicine, talocalcaneal impingement. Imaging findings that correlate well with synovitis or scarring at arthroscopy included nodular or irregular contour of the anterolateral recess. Up to 14% of the asymptomatic population may have an os trigonum [49]. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. 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].
